Raspberry pi

Has anyone used a raspberry pi to automate thier house heating/ventilation?

I have a quite complicated system which has wood burner(plumbed in with back boiler) combined with oiled fired combi boiler(fed into rads via plate heat exchanger), mechanical ventilation with heat recovery, solar thermal, solar pv(with diverter to heat water tank / convector heater), 3no. Hot water cylinders (due to space restrictions)- 1no. Pressurised +2no. Gravity fed, a fair number of pipe stats, 3speed rad pump rewired to run at speed dependent on water temp ect ect.

Already have a couple of rasberry pi's used for streaming and they have capability of running countless temperature sensors / relays ect. Plus my boy can program the pi and get it networked / viewable on smart phone /internet.

Anyone with any experience with pi and automation, I would love to hear your what it is capable of.

Let me think about it.

To give an idea of what I'm looking at controlling / monitoring attached a couple schematics of current system. All running ok, just looking for rasberry pi to control / monitor / log, plus would give easy access to view via smart phone.

try the raspberrry pi forums.

or google "raspberry pi home automation"

Take a look at Home Assistant.

You also might like to look at Arduino - IMHO more suited in some of the scenarios you may be looking at. And nothing to stop you mixing the two - arduino for sensors/device control, and HA running on a PI for combining everything.

Not personally, but a friend mentioned that his Swiss heating system failed, so he made a new controller with a Raspberry Pi.
He is a programmer by trade so this sort of thing is easy for him - I have no idea! But it should be possible if you know what you're doing - has quite a few of those on/off control ports on, so should be able to operate a few devices I think.

and you could have several set up I suppose, if you've a lot going on?

Use something like node red connected to the I/O via MQTT. Node red can take care of all the logic and MQTT can abstract the I/O. I use the Honeywell Galaxy alarm to connect my own sensors, reading their states into node red and in turn driving outputs but you can use any other MQTT compatible sensor/circuit. You don't need to use MQTT, but it is a great solution and allows many things to be connected together. Node red has many plugins for connecting echo dot and many more.
