TO REPRODUCE

AC is set OFF
Send over MQTT power/on
OR
Toggle Switch in Webui

EXPECTED BEHAVIOUR

AC should start

If applicable, add screenshots to help explain your problem.

ADDITIONAL CONTEXT

In my opinion the Line
07:39:05.250 MiElHVAC: sending FC41013010 01010000000000000000000000000000 7c
isn't correct.
I think the 8th byte should be 0x01 instead of 0x00

(Please, remember to close the issue when the problem has been addressed)

[bobbytables2048]

Same issue when I upgraded from 12.4.0 to 13.0.0. Flashed back down to 12.4.0 and power commands are sent successfully.

[s-hadinger]

I don't have the device, not know how the driver works. But I don't see any significant change that would explain the bug. Do you know which version broke it?

[bobbytables2048]

Here is what we know so far
12.4.0 - OK (compiled with tasmocompiler)
12.5.0.4 - Issue (as reported by @wegw3rf)
13.0.0 - Issue (compiled with tasmocompiler)

[arendst]

Try latest change in dev branch and report back.

[wegw3rf]

@arendst it looks like it works. I've tested the webui and mqtt, both will start and stop the airconditioner correct. Thank you for your help!

[arendst]

No problem. Was my fault anyway ;-)
