Hi Bernhard,
I am using KWL EC 450 PRO, connected to RaspberryPi via RS-485 and USB converter which works fine:
pi@raspberrypi:~ $ ls -l /dev/ttyUSB0 crw-rw---- 1 root dialout 188, 0 Aug 26 14:01 /dev/ttyUSB0
Connection is also fine as python script helios-usb-rs485.py returns (it’s not too hot at the moment):
bypass_disabled = 1 max_fanspeed = 8 inside_temp = 22 incoming_temp = 22 bypass_temp = 10 power_state = 1 exhaust_temp = 23 fanspeed = 1 min_fanspeed = 1 outside_temp = 23
Link to Tagol.de example: http://www.tagol.de/blog/anschluss-raspberry-pi-kwl-helios-pro---rs485
When files are copied I get all frames and items - looks great but no values (screenshot below).
Is it possible to configure your bindig (org.openhab.binding.helios_1.8.0.201601010916.jar) to work over RS-485?
Needs adding anything to openhab.cfg?
Kind regards,
Marjan
