Deye-12k-SG04LP3-EU 3ph inverter - error handling Low Capacity, use_timer and progX_charge

Your Inverter

Deye-12k-SG04LP3-EU, Firmware 1140 This is a 3ph inverter

Describe the issue/bug and what you expect

1. reading battery Low Capacity from the inverter is correct in homeassistant.
   Writing (using the slider) a value in HA sets the value to 0 in the inverter The expectation is that wenn I select a value like i.e. 50 in HA this value is stored/written to the inverter.

2. Unchecked Use Timer checkbox in the inverter is not read correctly. In the log we see: use_timer: Unknown register value 254 The value 254 is read, when the checkbox in the inverter ist unchecked. So the expectation is that this value is recognized as off currently the code shows: SwitchRWSensor(146, "Use Timer", on=255) maybe we need something like SwitchRWSensor(146, "Use Timer", off=254, on=255)

3. The 3ph inverter has for the prog charge options two checkboxes Grid Charge and Gen Charge. In the single phase inverter it is already coded to support the two options, so I expect it has also these options. Currently the 3ph implementation only handles 0 and 1, one bit of the bitmap and for the second bit we get errors in the log Log: 17:12:15 WARNING prog1_charge: Unknown register value 3 Log: 17:12:15 WARNING prog3_charge: Unknown register value 2 The expectation is that the second checkbox for Gen Charge is handled too, probably just like in the 1ph inverter. PROG_CHARGE_OPTIONS = { 0: "No Grid or Gen", 1: "Allow Grid", 2: "Allow Gen", 3: "Allow Grid & Gen", }

Thanks for the add-on!

On 2.

Try this definition with mysensors.py -- see the docs.

SwitchRWSensor(146, "Use Timer", bitmask=1)

On 1&3 you can experiment with the 1ph definitions on you 3ph inverter, just use the 1-ph definition in mysensors.py

If you do manage to fix these, please consider opening a PR to modify the 3ph definitions!
