Cannot read register 145 Solar Sell #4

Closed tpahula closed 1 year ago

tpahula commented 1 year ago

I am trying to read and write register number 145. I will get following error:

deye-regtest 192.168.1.x 2705xxxx 145

raise IllegalDataValueError('Quantify field of request must be a ' umodbus.exceptions.IllegalDataValueError: The value contained in the request data field is not an allowable value for the server.

What's the second value used in the command 146 ?!? I must admit that the --help of this tool is not correct end should be number of registers to be read. Try with 

deye-regtest 192.168.1.x 2705xxxx 145 1

and you should get the value (0 is the default I think)

Ok. It is working now. I can change Solar Sell value with commands:

Set Solar Sell enabled:

deye-regwrite 192.168.1.x 2705xxxxxx 145 1

Set Solar Sell disabled:

deye-regwrite 192.168.1.x 2705xxxxxx 145 0

How I can use deye-controller with Home Assistant ? I am using deye-controller in my OpenWRT router now.

You can't, unless a Home Assistant plugin is developed around it. You can use it for a convenient reading from / writing to the inverter. My personal use case is data collection and upload to a PostgreSQL DB + remote control of the inverter(s).
