I’ve recently bought a SmartThings hub, and bought a few Fibaro relays (these seem good… if a bit expensive).
I was thinking the other day that it would be nice to hook up the switch on my central heating thermostat override to the relay, so that I can turn on my heating through SmartThings.
Then it got me thinking, as I was working my way through all of the devices, that they could ALL be replaced.
At the moment, I have a Cosy system fitted by my FirstUtility energy supplier. This consist of…
- Electronic Timer
- Wall switch (this allows me to switch the heating on/off by pressing the switch)
- Cosy Hub (plugged into my router and power supply)
- Cosy Thermostat (RF device (I think) that communicates with the Cosy Hub)
- A Cosy app on my phone which allows me to control the schedule and switch heating on/off
The simple end result of this, is that based on either temperature/switch/time of day the CH is either on or off.
Now, if I rip out everything, and just put a Fibaro relay over the contacts of the boiler that switch it on and off, could I not just use SmartThings (and my voice via Google Home) to control every element of my heating without the complexities of the above? i.e. I don’t need a thermostat if I have an ST sensor with a temperature reading.
