 # Changelog
-### Not in a release yet
+## 0.21.0
 **A minor bump: control now holds the batteries when Home Assistant readings come late, Home draws the whole night's grid charge, and the shutdown 0 W is sent last. No option changes.**
 No option was added, removed or renamed, and no default changed (86 options). **Existing installs need no option change:** options that start 0.20.1 also start 0.21.0, and the Supervisor form is the same. It is a minor bump because control acts differently when readings come late and when the add-on stops; every saved setting still starts.
 **Late Home Assistant readings are held, not followed.** When Home Assistant passes readings on late, control used to correct a mistake its last command had already fixed, so the give run could swing and send power to the grid. It now waits until the battery shows its last power request, and the peak limit no longer asks for full power on late readings. A row on the page says so, and if the readings stay too late every inverter goes to 0 W. With readings on time, the commands are the same as before.
 - With a 2 s meter, readings 10 s late were found in 43 s in a rig test.
 - With a 5 s meter, readings 30 s late are now found in about 90 s (88 s in a simulation, 75 s in a rig test), where they took about 3 minutes. Readings 10 s late at a 5 s meter are not found ([[SAFETY-136]]).
 **Home draws the whole night's grid charge.** Home used to draw a battery's grid charge only for the cheap run under way. It now draws every hour the add-on will charge it tonight, and shares the peak room between batteries as control does. It shows the plan and changes no command.
 **Tomorrow's forecast stays in the afternoon.** If one of the tomorrow solar forecast sensors stops updating, tomorrow's forecast now stays instead of vanishing until 20:00.
 **The shutdown 0 W is sent last.** When the add-on stops, the 0 W now waits up to 2 s for a command already on its way, so it is the last thing each inverter hears. A command slower than that can still land after it ([[SAFETY-138]]).
 Contents of this release, in merge order since 0.20.1 (`d53f70f`):
 | | |
 |---|---|
 | `371961e` | When Home Assistant passes readings on late, control no longer corrects a mistake its last command has already fixed. It waits until the battery shows its last power request, and the peak limit no longer asks for full power on late readings. The page says so, and if the readings stay too late every inverter goes to 0 W ([[SAFETY-128]], #228) |
 | `af2d0d2` | History only: brings 0.20.1, already live, into this branch. Nothing else is new (#233) |
 | `47c89a1`, `c66aa7f` | Home draws a battery's grid charge for every hour the add-on will charge it tonight, not only the cheap run under way, and shares the peak room between batteries as control does. It shows the plan and changes no command ([[UX-77]], #234, with its second round #235) |
 | `b291262` | With a 5 s meter, readings 30 s late are found in about 90 s, not about 3 minutes. Readings 10 s late are not found at a 5 s meter; the owner accepted this and it has its own card ([[SAFETY-129]], #236, [[SAFETY-136]]) |
 | `23ff9d0` | If one of the tomorrow solar forecast sensors stops updating in the afternoon, tomorrow's forecast now stays on the Forecast tab instead of vanishing until 20:00. The night plan can use it in that time ([[OPT-38]], #237) |
 | `57c8d1b` | Each inverter is now reached through a driver. This prepares support for other inverter makes; there is no change for GoodWe sites ([[SMA-2]], #238) |
 | `dbdc37b` | When the add-on stops, an inverter that can steer itself can be handed back instead of held at 0 W. This prepares support for other inverter makes; there is no change for GoodWe sites ([[SMA-10]], #239) |
 | `b3cfcf2` | When the add-on stops, the 0 W now waits up to 2 s for a command already on its way, so it is the last thing each inverter hears. In a rig test, 0 of 111 stops ended on a value other than 0 W, against 4 of 110 before. A slower command can still land after it ([[SAFETY-137]], #240, [[SAFETY-138]]) |
 ### Known issues
 - A false "Battery is not keeping up" can still show when the peak guard pauses a maintenance charge ([[SAFETY-92]]).
 - A battery capped at a low limit with a perfectly flat reading can still trip the stale check ([[SAFETY-74]]).
 - A battery whose reading at rest is beyond about ±175 W is still not caught when it refuses ([[SAFETY-97]]).
 - The peak guard can still back off near the end of a 15-minute period when a meter reading is late, by less than 30 s. This is about the guard's discharge only; a grid charge is cut back since 0.19.2 ([[SAFETY-99]]).
 - Two inverters: the maintenance charge can switch on and off while the house is above the peak aim ([[SAFETY-88]]).
 - Two inverters: the "circulating" figure counts a battery's reading at rest ([[SAFETY-98]]).
 - Two inverters: a drain that starts during a big step in house use can send the other battery to full power, and about 1 kW goes to the grid for about 10 s ([[SAFETY-104]]).
 - Two inverters: when a battery comes back during a maintenance charge, the grid can step by several kW at once ([[SAFETY-101]]).
 - Two inverters: when a battery drops out during a solar surplus, the others can swing by up to 1.5 kW in a simulation ([[SAFETY-105]]).
 - Two inverters: after a drain ends, a change in house use can go unanswered for about 9 s, because some readings are old ([[SAFETY-106]]).
 - Two inverters: when one battery's level is missing, both batteries are held at 0 W, and for about 15 s the last command stays on ([[SAFETY-108]]).
 - Two inverters: if one battery's level stays missing for 12 h, the other battery's cycle can be marked failed, with a 7-day wait and a notice, though it is healthy. This comes from reading the code; it has not been seen on a site ([[MAINT-17]]).
 - When the 15-minute demand forecast sensor counts the battery's own charge, the maintenance charge runs at about half the power the peak limit leaves, so it takes about twice as long. Seen on a site: about 1.2 kW instead of 2.5 kW, and the peak limit was kept ([[SAFETY-111]]).
 - One inverter: after a link drop, the battery's own safety stop to 0 W can be taken as a refusal, and the site stays at 0 W for up to 15 min ([[SAFETY-102]]).
 - After a Home Assistant restart, control still waits until Home Assistant has finished starting, which can take several minutes, though the readings are already there ([[SAFETY-115]]).
 - While Home Assistant is not answering, the page can list inverters as refusing commands and sensors as missing, and send you to Developer Tools, though they are fine ([[UX-37]]).
 - If Home Assistant hangs or stops, the page keeps saying "Waiting for Home Assistant" and never turns into an alarm ([[SAFETY-113]]).
 - Right after Home Assistant has started, the page can say for about 4 s that an inverter cannot be controlled, and the first command can come late ([[SAFETY-114]]).
 - After a Home Assistant restart, the controller status sensor can still say "running" while the add-on cannot control. It was seen once, and the cause is not known ([[SAFETY-116]]).
 - Battery modes on: after a planned top-up from the grid, the Batteries screen can say "Enough sun is forecast" ([[UX-32]]).
 - Battery modes on: the forecast line "we count on" can show more sun than the plan counts, because the plan takes house use off first ([[UX-33]]).
 - Battery modes on: before a planned top-up, the Today list shows a smaller "gives" amount than the plan will use; it grows as the charge happens ([[UX-34]]).
 - Two inverters, battery modes on: while the other battery is in its maintenance charge, a battery's card can say it charges from the grid while it stays at 0 W ([[OPT-18]]).
 - Two inverters, battery modes on: while a battery refuses to charge in a cheap run, the action log on the page gets about 8 lines an hour for its retries, and the page hint says "waiting for a better price" ([[UX-38]]).
 - A battery in a safety stop, or one the add-on cannot reach, can still be started for a cycle, and its drain then waits about 12 h and ends in a failed-cycle notice. This comes from reading the code; it has not been seen on a site ([[MAINT-19]]).
 - On the Settings page, the rows of the solar forecast lists are labelled "Phase 1", "Phase 2" instead of "Sensor 1", "Sensor 2" ([[UX-27]]).
 - In the solar forecast list, a blank or repeated row makes "source 2 of 2" count differently from the rows on the Settings page ([[UX-28]]).
 - The solar forecast message says "has no reading" also when the sensor shows a number that is too old or in the wrong unit ([[UX-29]]).
 - If you use only the forecast lists, two Settings notes sit on the single-sensor field, and one of them tells you to set that field ([[UX-30]]).
 - After a restart during a price outage, the "No prices" message can say "yet" when prices did come in earlier ([[UX-39]]).
 - On the new settings page, you cannot see whether a price service token is set. Check the Configuration tab ([[UX-41]]).
 - On the classic settings page, the first click on Save after editing a field can do nothing. Click again ([[UX-42]]).
 - A steady overload on a 1 s meter can warn, and send the Home Assistant notification, 2 or 3 times at the start of each 15-minute period instead of once. The peak limit is still kept ([[SAFETY-122]]).
 - A fixed tariff is priced once per hour, so a price window that starts or ends at :15, :30 or :45 gets the wrong price for part of that hour. Windows that start and end on the hour are right ([[TARIFF-23]]).
 - Step 6 of the setup wizard stays empty because of an error in the page, in English and in Dutch ([[UX-51]]).
 - On Dutch pages, refusal texts, the last-event line under the Home buttons, the installer details and the trading status sentences are still English, and a few Dutch texts read badly, such as "1 metingen geweigerd" ([[UX-52]]).
 - Some price texts say "hour" where the add-on acts on a 15-minute period, such as "cheapest hour" ([[UX-47]]).
 - After the add-on restarts, the Home price chart shows no price for the earlier part of today, and the setup check can say "12 of 24 hours", though the prices are known ([[UX-48]]).
 - With battery modes on and only batteries on "Leftover solar", the Home price chart can mark a cheap period where no battery charges ([[UX-49]]).
 - On a phone, the bars of the Home price chart are too thin to tap one 15-minute period. The arrow keys work ([[UX-50]]).
 - In the last second of a 15-minute period, being a few watts over the aim can make the peak guard ask a battery for full power for one second. When a charge ends on a period edge, the last-second give can fade out over about 10 s, and a rig test exported up to 7.4 kW for about 8 s ([[SAFETY-124]]).
 - During the night grid charge, a 15-minute period can end 6 to 14 W over the peak aim, because the battery charges harder than asked. This was seen in simulation; a rig test saw 2 to 8 W ([[OPT-35]]).
 - The test rig could not bring back the false peak alarm that [[SAFETY-126]] fixes, so that fix is shown in simulation only. Watch the notifications for a few nights ([[TEST-35]]).
 - The night cheap run is sized for the batteries' full charging power, not for what the peak limit leaves. Under a tight limit the run can end before the batteries reach their level, and Home can show a level they do not reach (79.9 % against a shown 95 % in a rig test) ([[OPT-25]]).
 - By day, a Leftover solar plan that has only a daily forecast figure counts the sun from now, not from when the figure was read. It counts about 22 % too much for a figure one hour old; the night plan is not affected ([[OPT-30]]).
 - The night charge can buy too much in a house that uses more at night than by day, such as one with a car charger or heat pump, and on a sunny day, because spare sun in one expensive hour does not count for the later ones ([[OPT-31]]).
 - A cheap run that has already started can overlap a new give run after a re-plan, so a battery can charge from the grid at the dearest price for part of an hour. This was seen in a test case, not on a site. Also in 0.19.2 ([[OPT-32]]).
 - If the solar forecast sensors stop updating before 17:00, as in winter or further north, there is no forecast from three hours after their last update until 20:00 ([[OPT-33]]).
 - With a forecast that gives only a daily total, the sun is spread an hour off on the two clock-change days after the change. The day's total is right ([[OPT-24]]).
 - The add-on learns the house's use only once a solar forecast is set, so a site that adds a forecast later waits one more day for its first plan ([[OPT-26]]).
 - Home says "No trading on price yet: no prices have arrived" when every battery is on Solar first, though the prices are shown ([[UX-55]]).
 - The Home plan header can say "Charges in the cheapest hour, gives power in the dearest" when Home draws no charge, and it says "hour" for 15-minute prices ([[UX-56]]).
 - While the peak guard holds back charging, Home hides the rest of the cheap run and gives no reason. The charge starts again when the guard lets go ([[UX-57]]).
 - With battery modes on and selling on, Home can draw a "Sells up to" block when the add-on judges the trade not worth it, and then it will not sell ([[UX-58]]).
 - Home, the plan and the Forecast tab stop drawing a battery's give at the trading floor, though control goes on giving down to the battery's cut-out ([[UX-59]]).
 - During a price outage, the Batteries screen says "Prices differ too little" and Home says "The price gap is too small" ([[UX-60]]).
 - With battery modes on and no meter, or a meter that is a Home Assistant entity, a grid charge is not possible and nothing says so ([[UX-61]]).
 - On the Batteries screen, a charge the add-on refused in a cheap run reads as "Saves its power for ...", for up to 15 minutes ([[UX-62]]).
 - A Leftover solar battery with no capacity set never charges from the grid when a solar forecast is set, and nothing warns about it ([[UX-63]]).
 - The "How the modes work" box on the Batteries screen does not describe Cheap hours only ([[UX-64]]).
 - With battery modes on, Settings still shows "Trade on the price spread", which the modes ignore. A site with modes on and no price source starts, and the Batteries screen says "No prices, so it follows the house" without pointing to Settings ([[UX-65]]).
 - With battery modes off and several equal prices in a row, Home and the Forecast tab draw one price quarter, while the add-on trades every quarter of the run ([[UX-67]]).
 - Late in the day, the Forecast tab's "now" line and last bars sit over the axis labels at the right edge ([[UX-68]]).
 - The Forecast tab's level curve charges at each battery's full rating. Under a peak limit the levels it draws are too high and a charge block can end early (54.6 % shown against 39.7 % in a rig test) ([[UX-70]]).
 - The peak forecast check says maintenance charging is not kept under the peak limit when no peak forecast is set, but since 0.19.2 it is ([[UX-73]]).
 - The peak guard row can show the same figure twice, such as "at this rate 3 500 W, over 3 500 W". Also in 0.19.2 ([[UX-74]]).
 - If the inverter's setpoint entity appears in Home Assistant after the add-on has started, the page keeps saying "Inverter control: not found in Home Assistant" and the batteries say "An alarm stopped control" until a restart, though control runs ([[UX-75]]).
 - In the last minute of a 15-minute period, with Home Assistant readings 30 s late, the period can end about 80 W over the peak aim and over the limit: 3 530 W against a 3 450 W aim and a 3 500 W limit in a rig test with a 2 kW load added 45 s before the end. The peak guard sees the load too late to hold it back ([[SAFETY-133]]).
 - With Home Assistant readings 10 s late, the grid charge in a cheap run can swing by several kW. In a test the add-on asked for an 8.7 kW charge (9.6 kW on 0.20.0) ([[SAFETY-132]]).
 - A plan rebuilt while the battery levels are missing for a moment can drop a cheap run that has not started yet, so the battery does not charge that day. Seen in a replay of real prices, where it cost about EUR 0.40 of extra grid use; the Leftover solar change in 0.20.1 no longer triggers it in those replays, but the cause stays ([[OPT-37]]).
 - On a 5 s meter, Home Assistant readings 10 s late are not caught, and readings 15 s late only after about 4 minutes. With a changing load such as an oven or a kettle, 21 to 142 Wh can go to the grid in a simulation, against 2 to 27 Wh with readings on time ([[SAFETY-136]]).
 - With readings 10 to 15 s late, the hold can end in the middle of the delay and the swing can come back. Seen in rig tests with a 2 s and a 5 s meter ([[SAFETY-134]]).
 - With readings 10 s late on a 1 s meter, the grid can still move between -422 and +340 W while the batteries are held. With a very long delay (30 to 90 s) the request can swing by about 900 W every few seconds. Seen in review tests ([[SAFETY-130]]).
 - A battery that answers very slowly (10 s or more) can be taken for late Home Assistant readings and held, and the page then blames Home Assistant. A GoodWe battery settles in about 6 s and this has not been seen on one ([[SAFETY-131]]).
 - The page row for late readings reads awkwardly in English ("Home Assistant readings show requests about N seconds late, so control holds the batteries"), and the Dutch text misses a word ([[UX-78]]).
 - On a night grid charge held to the peak limit, the peak guard can stop the charge 1 to 3 s into a 15-minute period and keep it paused for that whole period. In a rig test this cost up to about 0.27 kWh of grid charge per run; it may come from the sped-up rig clock ([[SAFETY-135]]).
 - When the add-on stops, a write that takes more than 2 s can still land after the 0 W, and the 30 s safety timer on the ESPHome board then sets 0 W. After the Stop button, a cycle that had already decided can send its share (560 to 670 W) just after the 0 W; the next cycle sends 0 W again ([[SAFETY-138]]).
 - In the last hour of a cheap run, Home can draw a battery's grid charge up to an hour past the time control stops charging it. It only draws too much, never too little ([[UX-79]]).
 - A tomorrow solar forecast sensor that reports just after midnight with yesterday's value can be used as the new day's forecast for up to 12 hours. This has not been seen on a site ([[OPT-39]]).
 - During a cheap-hours charge, at some 15-minute boundaries the add-on sends 0 W for one tick ("no trade (headroom)") and then goes on. Seen in a rig test, in 5 of 8 cases; once, with a frozen battery reading, it left a battery at 0 W until 23:45 ([[OPT-40]]).
 ### If you are crossing from a version older than 0.10.0
 `## 0.10.0` below can refuse an old config: `slew_w` above its limit, and the
 withdrawn `price_provider` ids `engie_dynamic`, `totalenergies_dynamic` and
 `eneco_eddy`. Read it before you update. Run `tools/predeploy_check.py` with the
 bare options (`jq '.data.options'`) first.
 - When the add-on stops, a command that was already on its way can no longer reach an inverter after the 0 W. The 0 W is now the last thing every inverter gets, also when Stop is pressed ([[SAFETY-137]]).
 - When the add-on stops, an inverter that can steer itself is handed back instead of held at 0 W. Safety stops still hold 0 W, and a GoodWe site is not affected ([[SMA-10]]).
 - Each inverter is now reached through a driver, so another make can be added later. Nothing changes for a GoodWe site ([[SMA-2]]).
 - Home now draws today's charge from the grid for every hour the add-on will really charge, not only the run under way ([[UX-77]]).
 - When Home Assistant passes readings on late, control no longer swings on them: it waits until the battery shows its last power request, and the peak limit no longer asks for full power on them. The page says so, and if the readings stay too late every inverter goes to 0 W ([[SAFETY-128]]).
 - With a 5 s meter, readings 30 s late are now noticed within 100 seconds, not 3 minutes ([[SAFETY-129]]).
 - If one of the tomorrow solar forecast sensors stops updating in the afternoon, tomorrow's forecast now stays on the Forecast tab instead of vanishing until 20:00 ([[OPT-38]]).
