This project is designed to control both my Energenie radiator valves and my Salus RT510RF / RT510TX boiler controller.
It runs on a Raspberry Pi with an Energenie 433Mhz ENER314-RT https://energenie4u.co.uk/catalogue/product/ENER314-RT two way radio controller board attached.
I modded my ENER314-RT board to attach an additional 868MHz radio so I can control the Salus boiler controller as well.
It talks to an MQTT server to communicate with the outside world. On clean startup you need to:
- Turn the boiler receiver off and on so it starts flashing (== pairing mode)
mosquitto_pub -h beyond -t /boiler/pair -m '20'-- this will pair with the boiler using a code of 20. Code can be any integer from 1->65535, it is entirely up to you. The boiler will use whatever code you supply.- for your radiators, you'll need to do:
mosquitto_pub -h beyond -t /radiator/DEVICEID/desired_temperature -m '17'to set the desired temperature for each of your energinie radiator valves.
Looking at the ENER314-RT I realised it was using a HopeRF 433Mhz RFM69CW device.
I bought a similar HopeRF 866Mhz RFM69CW (and 866MHz helical antenna), and attached it to the same board using a different SPI Chip Select line.
Energenie devices use the OpenThings protocol.
The code for controlling the energenie valves is open source, but I found the various libraries impenetrable. I decided to rewrite it in C.
However, this rewrite only supports the radiator valves, not Energenie's entire product suite.
I found a few other projects which controlled the RT500, but it appears the protocol used by the RT510 is different.
