Service 'fixed charge/discharge periods' has no effect?

[timconinx]

Describe the issue

Setting my battery in 'Fixed Charge Discharge' mode, I tried to use the service 'Set Fixed Charge/Discharge Periods' to enable the battery to charge and discharge at fixed times during the day.

The service itself works insofar I got errors saying the times weren't formatted correctly (using 3:30 instead of 03:30) but after fixing those there were no errors and the attributed showed correctly in HA

However, no charging was done and nothing appears in the logs. I didn't change the battery's 'Fixed Charge Discharge' mode, power didn't exceed the global 'Grid Charge Maximum Power' variable... there was just no action from the battery

I did notice that nor 'Fixed Charge/Discharge Periods' setting, nor the service to change it are mentioned in the wiki documentation... did I try something too experimental?

There are no relevant logs

Please confirm the following:

• I'm running the latest release of Home Assistant.
• I'm running the latest release of this integration.
• I did not find an existing issue describing this problem.
• I did upload the diagnostics-file that I could retrieve from the 'Devices & Services Page'
• I did upload the relevant debug logs (via 'Enable Debug Logging'-feature or by manually configuring HA logging)

The integration successfully writes the TOU configuration to the inverter. How the inverter and battery act on that configuration is out of scope for this integration, and I do not provide any support for this whatsoever.

I'm converting this into a discussion, hoping that other users can help you with this.

Thanks @wlcrs

Just as a clarification: TOU periods (set by set fixed TOU periods ) absolutely work. Fixed Charge/Discharge periods do not. I agree that this is a matter of how the inverter/battery works with the difference between the two.

Here's hoping other people are experimenting as well with these new(?) features

I just started playing with this, since it may be useful for my EMHASS setup.
I can confirm that something does not work as intended, reproduced by Developer tools -> Actions -> Huawei Solar: Set Fixed Charge Periods, choose the battery, then just copy and paste the line in the example (12:00-15:59/-1000W) gives Unknown error. However, without the negative sign it gets accepted (12:00-15:59/1000W).
