Anyone has any idea why RTU scan show no result?
I tried baud rate 9600, parity none 1stop bit, half duplex, scan from 1 all the way to 247, nothing.
This thermostat was a relative cheap chinese made, PCB reads: ETOP-HT-0506-MDV1.1, which was made by company E-TOP, they are known for making OEM products.
And for this model, the common specs are using 9600-8-N-1.
What could be the problem here?
