I too replaced my dying PoS Rainbird irrigation controller with a raspberry pi and a relay board. > With cron, I can schedule things however I want! 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. 1. https://github.com/rszimm/sprin…

What did you dislike about your Rainbird system ?

I installed my own sprinklers and drip - 22 zones of it. A Rainbird controller was going to be nearly $300. I went with a pi and loved it. Then came the real problem - I put the home on the market and ended up replacing my pi with a rainbird for the next people. Why? I kinda wanted to keep my setup and buyers didn't know what to think of it.

After I swapped it out I missed quite a few things - controlling it from my phone, from home or remote, being able to pull up a graph and see how long each zone ran. I wasn't in the mood to get up at 3am to see if the rainbird was working so I crossed my fingers and hoped it would work at least until the house sold. Setting up all my zones was a lot faster on the pi than it was with cranky dials and buttons on the rainbird. I won't miss it.

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.

If you are somewhat of a "programmer" you can complete that integration using a RPI and a software package called "Home Assistant".

They have links between Vera and the Echo along with a TON of other things.

Nice project. Mine isn't quite so ambitious (yet). I just need to monitor water pumps. Does anyone have a suggestion for a water flow sensor? I need to detect if there is water present at the pump input. So far the only thing I've been able to get my hands on is a water flow meter [1]. But it's overkill because I don't need to measure flow rate, only presence of water.

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…

For radiator valves look into actuators like this, there are a few different manufacturers:

I managed to get bilingual voice activation (Alexa and Siri/HomeKit - maybe Google Home in future) working with Home Assistant, homebridge, pi-mote, raspberry pi 3 and four energenie sockets. (In the US I guess you could use etekcity sockets) https://home-assistant.io https://github.com/nfarina/homebridge https://energenie4u.co.uk/catalogue/product/ENER314 https://energenie4u.co.uk/catalogue/product/ENER002-4 I would…

Home Assistant is awesome. So much cleaner than OpenHAB. I just wish it supported Insteon PLM natively. For now, I'm making REST calls been OpenHAB and home Assistant to support this.

Could you use something to measure resistance? Like two wires, so when immersed resistance drops?

I'm sure that would work, at least initially. I'm concerned about reliability. My water has very high levels of calcium carbonate which quickly scales up everything. I think the electrodes wouldn't last long. A nonintrusive solution would be great. I've seen nonintrusive water flow sensors that use ultrasound to detect the flow of water. They are industrial devices and their price makes them unsuitable for my use.

There are cheaper optical water level sensors in the aquarium trade that might work for you. Check out the Tunze Osmolator as an example. It could easily be connected to a GPIO on the pi.

That's a very interesting idea. Thanks for the suggestion. It is still invasive since I have to cut the intake pipe and insert a section with the sensor installed in it. But it is more flexible since I can install it in any size pipe. And for my use case of a 1 inch input pipe it can be cheaper than my current solution. For example https://www.aliexpress.com/item/15mA-5V-Optical-Infrared-Wat...

Although, I wonder if scaling (as in hard water scale) is still going to be an issue.
