Voltcraft CO-100 to Domoticz
Posted: Saturday 16 April 2016 20:24
The Voltcraft CO-100 measures CO2 levels, temperature and humidity and displays it on its own display.
It also has an RJ45 port where the measured values are available as a 3.3VDC, SPI encoded bitstream.
Using the Arduino IDE I wrote some code for the Digistump Oak (an ESP8266 board), which measures and decodes the data and uploads it into Domoticz using MQTT (with knolleary's pubsubclient library). I also wrote an example for Arduino, so if you happen to have an Arduino with an ethernet shield then you can use that too.
For temperature and humidity it uses Domoticz's "THGN122/123, THGN132, THGR122/228/238/268" device and for CO2 it uses the Voltcraft CO-20.
Works like a charm!
