Arduino sketch which reads out Technische Alternative UVR31 solar heating control. Readings are send via nRF24L01+ to a python receiver. Measurements can be accessed and visualized with openHAB and emoncms.

UVR31_RF24

The Arduino sketch in this project reads out Technische Alternative (TA) solar heating control UVR31. In my setup readings are then send via nRF24L01+ radio module to a Raspberry Pi, where a python script subsequently forwards the readings to openHAB (http://www.openhab.org) and Emoncms (http://emoncms.org). These web-applications provide persistence and visualization services and also provide access to the readings via mobile applications. The signal processing part of the sketch is based on Elias Kuiter's project uvr2web (https://github.com/ekuiter/uvr2web), who works with a similiar TA solar heating control (UVR1611).

You can’t perform that action at this time.
