Just to rule some things out, what gen inverter and firmware revision are you using? Have you recently updated the firmware? I think Trefor has the same issue on his gen 1 hybrid with the faster firmware.
I know that the pause command isn't currently controlled by rest and relies on the GivTCP entities.
Are these unhashed in the apps.yaml file?
If you have a gen 1 then it doesn't set the pause times, so don't need those.
It's all working ok on my AC3, so sounds like something has changed for you that may be contributing
Gen 1 hybrid
Firmware is all way older than my issue
Inverter Firmware Version D0.450-A0.451 Last Update Time 2023-11-26 23:47:43 Battery Firmware Version 3015
I have unhashed the Giv TCP entities in apps.yaml today (but they weren't a week ago when things were working, I presumed through rest) and that doesn't seem to have made a difference. Predate tell me I am free charging right now but my battery is supplying all house load.
GivTCP log since midnight (when freeze charging should have started) is below

Thanks for your interest!
Predbay planned freeze charging until 00.30 and then idle mode. At 00.33 i started a manual freeze charge. You can see givTCP sending different target SOC for idle or freeze but it doesn't seem to be following them.
In reality it stayed in idle mode the whole time.

At 00.37 I used givTCP to turn on "eco (paused)" - temporarily the inverter behaved as expected but then reverted to eco mode (presumably directed by predbat)

Looking at your firmware version, its the older one that doesn't have the new battery pause mode enabled. So you were right to have had the pause entities hashed out in apps.yaml, so I'd change that back
As far as I know, to pause charge on D0.450-A0.451 firmware Predbat would raise the reserve level to the current SoC (it seems to be doing this from the logs) and also set battery discharge rate to zero. You could check homeassistant to see what happened to these at the time pausecharge should have been set. Otherwise probably best to upload a whole log file that captures when it happens.
I don't think you can directly select ecopause, it is set by a combination of other entity states - not 100% sure which
Only other thing to try is a reboot of the inverter, see if it makes any difference
I think its a bug, normally reserve is used to hold the charge but it wasn't setting it.
Fix on 'main' for testing, sorry I can't try it myself as I'm away.
Thanks - I've updated to main. Will see how it gets on when the sun goes down.
Any luck?
All seems to be working as expected now - thank you for investigating and finding a fix
Describe the bug Freeze charge from the plan used to work very well for agile prices that were reasonably cheap but not worth using for charging. My last successful freeze charge was on 21/7/24.
Since then I have had numerous freeze charge in the plan, none of which have done anything. Manual freeze charge from predate does not work. If I change GivTCP to "idle (paused)" while predbat is freeze charging then predate changes it back to idle.
Charging form the plan and manual charging are both working as expected - just seems to be freeze charging that is not.
Expected behavior freeze charges works as it did previously
