HomGar RainPoint Rain Sensor

I bought a cheap rain gauge with RainPoint branding and, because the rest of RainPoint’s irrigation equipment is set up with Tuya devices, I imagined that this would be similar and I’d be able to get it through a TuyaLocal integration. However, neither its hub nor the rain gauge is picked up by Tuya app. The hub and rain gauge don’t even appear in the Tuya app and looking at the generic devices doesn’t help.

Any experience with this equipment? I’m assuming its a lost cause. Googling the model number and PCB text yields nothing…

Not yet, but a few brands of irrigation controller / sensors use HomGar now and there’s a few posts on it so I’m hoping that someone with the skills creates an integration soon.

I really hope someone creates a solution for this system too. I bought one of the Diivoo multi-port valves on Amazon and miss the ability to use Siri to activate it like I could with my Eve Aqua.

Toujours rien de trouvé concernant l’intégration des appareils Homgar sur HA ?

Just to follow up on this…

I ended up ripping out the internal logic boardnand replaing it with an ESP board with magnetic pulse sensor.

Thankfully, the rainguage is on my roof and so i can power it with a USB connection power supply that ive repurposed from a raspberry pi adaptor (and extended the cable by splicing some speaker flex cable).

It’s working excellently!

If the device exclusively uses the HomGar app, you can integrate it into home assistant by adding it to google home, and then using the google assistant SDK and an easy to build automation to send commands to google home to toggle on and off the devices. I was able to add a 3 area Diivoo sprinkler switch into HA by doing this. I bought 2 Diivoo sprinkler controllers, and one uses the Tuya app natively, so that was easy to integrate into HA. The other, for some reason only uses the HomGar app, so had to use this workout and now both are working perfectly in my HA.

thank you very much! I did as you wrote and it worked!! many thanks

sorry I’m a beginner. I have a baldr weather station that uses the homegar app. can you explain to me better how to integrate it into home assistant? thanks in advance

I need to setup a test HA environment and copy these files over to make sure they work.

Still double checking the code.

is this integration up and running now?

Connection au cloud via l’api : ok,
Mais Impossible de recuperef mes equipements : mini hub et rain sensor !
Idem avec googke home

I want to buy also a RAINPOINT rain sensor
is it working ok in HA. If yes can you share a screenshot so i can see the inputs?

There is a klugy way to integrate Rainpoint Sensors. Using the app, create smart notifications for each sensor – something like when humidity falls below xx% send an email with subject line: Planter X needs watering (you can do one for Replace Batteries as well). Do this for all your sensors. Set up an email in google that’s just for your HA integration and add an app password. Then add the IMAP integration to HA and include your new email. Then you can set up an helpers, automation, script and dashboard card that activates when the email is sent. Attached is what the final card looks like. It will display OK until an email is sent saying that a specific planter needs to be watered or the battery replaced. I have to manually clear the notifications but other than that it works pretty well. I used ChatGPT to help me set it up. Happy to share code and specific steps if helpful.
