Tuya Irrigation Hardware (Rain Point) - Problems with Integration

Hardware
10

I’ve been using it using the scene workaround described by @gagga. With some automations I look at rainfall today, predicted rainfall tomorrow, temperature and determine whether to fire the scene. I have scenes defined for different durations of watering, although I ended up only using one.

thanks. off topic: How is the battery life and what is happening when battery is low? Is is possible to remain open ?

12

I don’t know the battery life yet as I haven’t had them long. Maybe the Tuya app will notify me when the battery’s low? Not sure.

The intent of these is to open up when you wish to water something, so if they were open when the battery fails that’d be bad. The garden would flood.

Hello there,

Did you find a way to get irrigation system state in HA ?

Thanks,

I don’t have this, but maybe someone at localtuya might be able to figure it out.

To help some others I am proving some more details about the process:

  • You need to get the yellow version of the irrigation controller and the gateway. The green version uses Bluetooth and it won’t work.
  • You need to pair the gateway and then the irrigation controller with the TuyaSmart app. Do no use the Rainpoint app.
  • Then after setting up the app go to the tab named Smart and add a Tap-to-Run action and set it to turn on the irrigation controller. This shows up in Home Assistant as a scene.

  • The action starts a timed watering process which turns off the irrigation controller automatically. You don’t need to worry about explicitly turning it off.
  • Bonus: The TuyaSmart app supports Alexa, Siri and Homekit

Very satisfied so far with my purchase. I was looking into a “similar” system from Kärcher that was 5 times the price.

Thanks for the detailed instruction & remarks
Does it still get detected if you’re using localtuya component?

I didn’t manage to connect using LocalTuya. Even though I have gotten the device id and local key for my device, I am getting an connection error when entering them in the integration. Not sure what the problem is.

However I have read that this fella has managed to make it work.

What I’ve done is the following:

  • Created 4 smart actions per % (25/50/75/100), that HA sees as scenes
  • Created the device with localtuya with 2 sensors, one for % status and one for timer remaining

I know is not the best solution, but at least it gives you a quite good control, and allows you to create schedules and automations

Hi
I am able to create the scenes (on and Off something like that), however I cannot create the local sensors using the Local Tuya integration…I mean my devices (I have 3 :-)) do not appear …(and yes I already got the local key, all that is needed but I simply cannot select (only) those devices if I try to add them via the Tuya local integration…What am I missing here ? Any idea that could help me ?
Thanks
Pedro

Do you have any other Tuya device working fine with LocalTuya integration? Honestly i don’t know where/what could be the reason why you cannot add them to the integration.

21

Yes I do. All my Tuya Devices work fine on the local Tuya, except these 3…simply these 3 devices do not appear if I try to add them via the Local Tuya integration… (maybe because they do not have a local IP ? since they are controlled via the hub ?). Because the HUB I can add it but not the devices …I even tried to configure manually and I have everything except the host (IP address that I cannot find it since it connects directly to the HUB). Any idea why / how to solve this ?

22

So you mean that they are not directly connected to the network but instead they are managed via a hub (Bluetooth?) and it’s just the hub connected to the network?

If so yes, this is the reason why you cannot see them to be added to LocalTuya.

Mine is a wifi valve, that is why I was able to set it up on LocalTuya

23

Correct they are connected to the HUB (not via Bluetooth its a “kind of” wifi/ZigBee protocol). I even can see then on the Tuya IoT Platform… This is the model I am using (exactly the one that is referred on the header of this post):

Thanks
Pedro

24

In any case they are connected via a network hub, and that’s why you cannot see them on the LocalTuya, as because they do not have a direct network connection.

25

Hello

So you do NOT have any Hub ? I thought you sued the same model (Rain Point devices with the Hub)…
(Those 2 sensors that you’ve created: they are “linked” to the Tuya device or they are just independent ? )

26

What exactly does your % actions mean? Via the latest Guys Smart integration, Tap to Run I can create on and off scenes but do not know how to create a scene that is on for a defined time, then off.

27

Where do you get the Tuya IoT Access ID and Tuya IoT Access Secret?

28

Would you be willing to share your code? I’m trying to do the same thing, but want to somehow accumulate the precipitation to date and trigger the irrigation if it falls below a certain level and it’s forecast not to rain.

Scenes are working properly in HA, so I can turn on/off the irrigation. However, how can I visualize the water flow from the sensors in HA? I want to see the water usage per day, similar to the app. It would be great if someone here has managed to get this feature working in HA.
