isystem-to-mqtt's Issues

Compatibility with Diematic BUS

I tested your code with other boiler - De Dietrich MC25 and Diematic 3 console. It have different Modbus addresses, for example:
"outside/temperature" - 7
"zone-a/day-target-temperature" - 14
"zone-a/night-target-temperature" - 15
"zone-a/mode" - 17
"zone-a/sensor-temperature" - 18
"zone-b/day-target-temperature" - 23
"zone-b/night-target-temperature" - 24

May good option is to parametrize READ/WRITE tables and read sequence with version of boiler?

SyntaxError? / Python 2.7 incompatibility?

I'm getting an error:
pi@rPi ~ $ dump_isystem.py --serial /dev/ttyUSB0 --deviceid 10
File "/usr/local/bin/dump_isystem.py", line 62
print("{0:4d} => {1:5d} ".format(address, raw_values[index]), end='')
^
SyntaxError: invalid syntax

What could be the reason?

Checksum error in rtu mode

hi,
i find your git very helpful. Unfortunatelly lastly i started to get some issues. My setup is rpi with dietpi on it, connected with boiler via ftdi rs485 cable (with udev rule thus named tty device).
Could you please point me what is my problem ? I run poll_isystem as a service, below you can find log from status. Neither restarts of service nor whole rpi will not solve the issue. The script can work for few days, then for few days will note send any mqtt messages, and than can start to work properly out of nowhere.
