Hi!
Am new, so apologies on forehand for a possible stupid question
Spent week on getting HA up and running on a rpi4 with everything in my house. Managed to do 95% with the help of google and existing community forum feedback or existing posts.
Due to reason decided to go to HA-OS. Problem with that is restricted access. (Tried some things to get around, like add-ons, but till no success). 2 problems remained:
- could not get serial port to work in rpi4 in HA-OS
- could not get a rtsp server installed on HA-OS.
So decided for a second rpi (a rpi3). The second rpi has now the rtsp server serial is working.
What i can’t get working is running a pymodbus serialclient on the rpi3. I want to point the HA modbus integration on the rpi4 (tcp, rpi3 IP address, port 502)) towards rpi3 serial.
Can find very little (good) examples of a decent pymodbus serialclient to get the job done.
Asking help for:
- is pymodbus the best way to go in this case (rpi3 serial connection to SDM630)
- any example for pymodbus serial for this use case anyone can share?
Thanks in advance for helping this noob
