OWON Zigbee Thermostat

[leonardpitzu]

Device

• Product name: Zigbee Smart Thermostat

• Manufacturer: OWON Technology Inc.

• Model identifier: PCT502

• Device type : Thermostat

• Product name: Zigbee Smart Thermostat

• Manufacturer: OWON Technology Inc.

• Model identifier: PR412C

• Device type : Thermostat (relay i guess?!?!)

The device bought comes in 2 pieces - one "desk clock" which measures temperature and humidity and is the actual "brain" of the thermostat (stores date/time/schedule) - and one relay connected to mains (it has 2 internal relays for various boilers and heaters - most basic central heating system in Europe is a on/off system). Product is labeled on the box as "OWON Zigbee Smart Thermostat PCT502-Z" without mentioning the second device product code. The "desk clock" contains also a rechargeable battery.

Edit: pairing goes through the desk clock only. If the relay is not powered the thermostat complaints that "network is disconnected"

Screenshots

Tbh, I got no clue how to properly support that thing, especially remotely and without traffic sniffing. I could give it a shot but you should provide additional screenshots of the thermostat cluster's attributes while those have been read and be able to compile a test version of the REST API plugin yourself to test.

Compiling would be no issue as is debugging. Sniffing in zigbeeland I do not know but I am willing to start working on it

Sounds good. Then don't forget about the screenshots. I guess I could give you something at hand almost as good as a bare zigbee sniffer ;)

Is there anything more i can provide or do in order to help with the issue?

[SwoopX]

I'd need the remaining thermostat cluster attributes from attribute 0x0012 downwards. I'm afraid you'll probably need to manually read each of them via a double click on the value.
