My HA instance (M1 mac, Big Sur using rosetta) appears to work fine as it can detect and connect to devices on my network but modbus tcp will not work.
The script syntax checks out but the system won’t even generate logs.
Is there a way to test if modbus is operational?
I have followed the various threads on the subject and none helped.
Issue resolved.
On the Mac HASS tries to load Pymodbus but does not report it failed.
I did this on an intel Mac and M1.
You either need to manually install Pymodbus with pip or first uninstall it then reinstall it.
There are many dependencies not included in the guide, such as ffmpeg that also need to loaded first.
