Upgrades… Salus RT500RF 868MHz wireless boiler control

RT500RFI’ve just received a Salus RT500RF in the post. I’m pretty much all prepared to hack this thing, at first I’ll sniff the airwaves with the RTL-SDR and try and get a handle on how it works. There’s been at least one blog article regarding this unit so I’ll also have a dig around them and see what they can tell me too. The idea is to get the Raspberry Pi with the 868MHz RFM12B to send a signal to turn the heating system on/off, and if possible, interrogate the current state of the boiler.

This will be the first stage in smartening up the house. The OWL CM160 and the Salus RT500RF are the first devices that I’m going to mess with as they’re the most useful to me right away. Next I’ll be turning my hand to Oregon Scientific weather sensors, Wireless door bells and other hardware on the 433/868 bands. These bands of course are used in Europe and some other locations, the equivalent is 315/915 for the US. So if you’re following my work then make sure you pick up the right bands for your location. It’s always best to buy radio transmitters and receivers in your own country because the likelihood of anything being on sale which isn’t allowed is reduced.
