I am referencing this Prior solution for setting up reporting of the TRB255 ADC voltage via modbus and MQTT here:
This worked well for about three weeks before it now suddenly stopped working over and over again. It often now shows the voltage as 0V even though the voltage is 12.5V or over.
A reboot usually fixes the issue for briefly, before measurements drop to zero again.
Is there some overrun of the modbus database or what could be causing this?
I’ve noticed accessing the modbus tcp client page remotely often takes so long that it times out, whereas all other pages open almost instantly.
