This looks like a lot of fun! Using a RaspPi is really attractive to me because you can make everything interoperate, and nothing depends on some company's servers. I've done two Pi projects now that I keep meaning to blog about. One was a sprinkler control system. My old system was dying, and not very flexible, so I decided to run everything off a Pi. The tricky part was driving 13 sprinkler lines with 24V AC curren…

I too replaced my dying PoS Rainbird irrigation controller with a raspberry pi and a relay board.

Wait, are you not using sprinklers_pi[1]? I highly recommend it.

I have more home pi/arduino/IoT projects coming up, but I am thinking it's going to be a lot of work integrating them. I'd like one home app/page that integrates them all.

Earlier quoted context omitted.

Is the relay for your heater controlling the main voltage input or is it controlling at the thermostat connection? I've been wanting to do something similar with the units in my apartment (they're similar to what you'd see in a hotel window unit). The thermostat and controls are integrated and I can't disassemble to access them, so I either need to build a rig to push the buttons (hard) and turn the temperature dial…

The relay is controlling the main voltage input and it's similar to http://i.ebayimg.com/00/s/NTAwWDUwMA==/z/ZS0AAOSwr81UNgc9/$_... . The relay's function is to act like a central switch. I have also a servo attached to the thermostat and it's only role is to spin the thermostat controller. The servo is similar to http://www.conrad.com/medias/global/ce/2000_2999/2000/2060/2...

You could also look at SSRs, which tend to be easily controllable with logic level outputs on a microcontroller.

What did you dislike about your Rainbird system ?

Cool, working on a similar project, but having a different stack

1. Z-wave switches/outlets/locks - all lamps, receptacles and locks controlled by Vera Edge; 2. DSC alarm system - door/flood sensors, integrated with Vera; 3. Nest cameras - not integrated; 4. Nest thermostat - integrated with Vera and Alexa;

Currently trying to integrate Vera and Alexa to have fully voice- controlled home.

There's some really useful stuff going on there - nice write-up.

Anyone getting into this field should take a look at Peter Scargill's Tech Blog - he has published details and code for a home control system centered around a Pi using MQTT with a range of modules (mostly ESP8266). The most interesting recent stuff is on control, monitoring and dashboard design for phone and Web apps - his work on the dials and gauges is very good.

Pete also takes a regular look at other non-Pi platforms from an IoT control perspective.

1. It didn't work reliably

2. The UI was awful and buggy

3. It finally broke outright and replacements with halfway modern features were pricey

Ok, Here is what I have been thinking of:

a PI, many sensors and controls. the pi to do the things the pi always does. the sensors to sense room temp. in each room. And this is the hardest one, flow control per radiator.

I want that I can set room temp schedules, and can go off schedule using the app (manual intervention) When the current temp in any room is below the set temp for that room the heater system turns on The rooms that are already above their set temp have the radiators turned down.

Why? Because I don't like to waste heat to a room I don't enter 90% of the day. And when my living room has reached the target temp there is always a room that is either still stone cold or feels like sauna.

The hardest part about this is the controllable radiator valves, the rest already exists.
