For anyone interested in taking your Rainpoint / Homgar irrigation system to the next level, I’m happy to report that it is now possible to monitor and control your Rainpoint devices from within the “Home Assistant” open-source smart home ecosystem, thanks to a newly created integration:
I wasn’t involved in its creation. I’m just a happy user. Now, in addition to being able to control my Rainpoint devices through the Rainpoint Home app, I can control and monitor them via my Home Assistant smart home system.
For example, I’m using the illuminance output from my HCS021FRF Soil Sensor to determine if it is sunny or cloudy outside. If it is sunny and also late in the afternoon, I’ve created an automation in Home Assistant to close my smart blinds to avoid being blasted by late afternoon sun in my family room.
Home Assistant has great weather forecast information, which I plan to use to automatically decide whether it is worth watering in the morning when it is likely to rain in the afternoon.
My next project is to use Home Assistant and the Rainpoint integration to create a DIY motion-activated sprinkler using one of my Rainpoint valve controllers to scare away deer that eat my strawberry plants every season.
Thank you so much for sharing this! We are delighted to hear that the Home Assistant integration is working well for you, and we truly appreciate you taking the time to post such a detailed and helpful message.
It’s fantastic to see how you are using the illuminance data from the soil sensor to control smart blinds, and we are especially excited about your motion‑activated sprinkler idea to deter deer – that is a very creative use of the system!
Your feedback and examples will certainly help many other users who want to integrate RainPoint into their smart home ecosystems.Thank you again for being a part of the RainPoint community and for sharing your insights.
Hi @Ruddy - Here is something else I discovered is possible to do with Rainpoint devices via Home Assistant.
In addition to having two of your newer water timers (HTV213 and HTV245), I have several older, Tuya-based Rainpoint water timers (TTV203 and TTV103). I learned several years ago that that the old and new Rainpoint devices are incompatible - i.e. they operate on different hubs and require different apps to control them (“Rainpoint Home” app for the newer devices vs. “Rainpoint-TY” app for the older devices). As a result, I retired my older devices when I acquired the newer ones.
But now that I’ve got the new devices integrated with Home Assistant, I decided to see if I could get the old ones integrated too. Sure enough, I was able to. Here are the steps for anyone interested:
In the Rainpoint-TY app, delete the older, Tuya Rainpoint devices (e.g. TTV203 and TTV103).
Put the the Tuya Rainpoint devices in pairing mode and add them via the “SmartLife” Tuya app.
Create separate “tap-to-run” scenes to turn on and off each valve of the Tuya Rainpoint devices.
Install the “Tuya” Home Assistant Integration via HACS.
Log in to your SmartLife account via the Tuya Integration to import your Tuya devices & scenes into Home Assistant.
The “tap-to-run” scenes that control your valves will now show up as entities in Home Assistant. Here is what one of them looks like:
When I hit “activate” for that scene in Home Assistant, it runs the scene which opens the corresponding valve on the TTV203. Once I had a way to open and close each valve of my Rainpoint Tuya devices in Home Assistant, it was easy to add them to my irrigation dashboard (as “Front Hose” and “Side Drip”) :
The beauty of accessing Rainpoint devices through Home Assistant like this is that both visually and functionally you can’t even tell that my irrigation system is now a mix of newer and older Rainpoint models, controlled by two different Rainpoint hubs. They all look and function the same once integrated into Home Assistant.
