My house is 3 floors, I've 12 rediators and a Gas boiler which provide both hot water for dometic usage and, with circulation pump, hot water for heating.
I was using just boiler thermostat to turn it on/off based on time, but I was alwasy having unheaven temperature acrosso all floors and even rooms in the same floor as the thermostat is the only place where temperature is read to decide if boiler must circulate or not the hot water.
I replaced the actuators of one floor with Homematic IP ones (4 x HMIP-eTRV) installed a lan gateway (HMIP-HAP) and a wall temp/hum reader (HmIP-STH) as 2 of the 4 radiators are in the same room I thought I could have this device to provide them the reading to control temperature.
So far all it seems to work but I feel the app is very simple and not providing enough info (e.g. I cannot see the reading of the actuators temperature and I cannot know if they are close, open and eventually how much open).
Looking on google I landed on this forum, I am reading a lot but I can't read German and this looks like a limit to better understand what I need to do next
This is what I learned so far, but I woudl apreciate some guidance before buying more deviced/hardware to complete my setup:
- I first looked at CC3 but then I understood a RaspberryPi + piVCCU/RaspberryMatic can replace it 100%
- I am quite experience with Raspberrys (I do have few running other devices in my home) so I woudl like to go this direction
- Despite the RaspberryPI itself, shoudl I buy mandatory a RF device and remove the current HMIP-HAP?
- Isn't possible to use both in order to have better coverage of the house as it's quite big and on 3 floors?
- Once I replace all manual actuator with HMIP-eTRV I would like to remove the old thermostat and control the boiuler circulation with Homematic IP system but I cannot find enough info
- My boiler needs a "dry contact" that when closed activate circulation for heating and when open not, can I use HmIP-PCBS and with RaspberryMatic control the boiler based on actuators status (e.g. simple rule like --> when at least one of the actuators open turn-on HmIP-PCBS and when all actuators are closed turn-off HmIP-PCBS?)
- As I'm using a lot NodeRed to control many "things" in my house, is there any way to integrate the HomematiIP system in NodeRED? If yes where can I find more info/resources?
Thanks to everyone that will be able to help or at least drive me to the right direction as I'd like to buy all I need as soon as possible and start the setup of converting whole house heating system
Not sure, though, if it will run with Raspberry, better to check.
