In Loxone and Shelly there is an option to add the location and position of your home, in the case of Loxone, depending on the weather in your city.
This reads the shadows that are falling on your window and so can act on them, for example if the window is facing south a scene is created that closes it in summer when the sun is shining or opens it in winter.
The other option is the rain radar, not the forecast in this way you can create a scene to close the blinds during the rain as sonoff directly has no rain sensor if flooding and you can make a diy one but always closes and never opens if you are not attentive to stop raining and manually dry the diy sensor.
Indeed, weather based automations are quite requested, will try to push the app team to make it happen, for now, other third party services like IFTTT is recommended.
As for the rain sensor, i think water leak sensor is a “alternate“ for rain drop detection.
In ifttt I haven’t seen any RainAlarm type that I use in iOS and neither a good weather one for my area.
I have a flood one but it is not practical, it activates but you have to wait until it stops raining to dry it well and use it again.
It is not practical either, especially if you are away from home.
There are some that dry with heat but they are not ewelink.
Others that do not detect water but use a seesaw that moves and empties when it fills with water, this would be good but you have to make a diy so that when it does not move it means that it has stopped raining.
On other platforms there is one that you put your position and orientation of your home, windows and it lowers the blinds when the sun shines in summer and opens them in winter.
Something like the weather or a sensor that actually measures that it is raining and detects when it is not raining.
The flooding one still shows rain until you dry it manually.
I would like to know which one you say for IFTTT to see if it is the same one I saw.
Then make it compatible I also have a sensor with heating, and it has four wires. Two are for positive and negative and the other two are from the dry contact. I have a small 12V power supply and a sonoff mini in a housing. I connected the two wires from the sensor contact to S1 and S2 and supplied 230V power. When the sensor gets wet, the heater starts, and as soon as it stops raining, it takes 2-3 minutes for the plate to dry. Unfortunately, no water drop icon is displayed in the app.
I thought about it but I haven’t decided which one to use yet.
I even thought about using the leaky one and adding the cable but this system once it gets wet it always shows water and it takes a long time to dry out even with the humidity at night it shoots up.
That’s another option I have on the list.
And another one that only marks pulses when the water falls is the one I like the most.
Because if it stops raining, there is no pulse, so it is necessary to make a scene when it stops raining for a while without pulses.
This is the one in the photo. But it is Rs485, it has to be adapted.
If I understand correctly, you are powering it with
illuburg LED Transformer 12 V 6 W connected orange wire on +
and orange-white wire to - . Blue wire is connected to S1 on
Sonoff MINIR4 and blue-white wire to S2 on MINIR4.
MINIR4 is powered with 230V AC on Lin live wire
and N neutral wire.
I just measured the consumption of the sensor. When the sensor is wet, it’s 174 mA, and when it’s dry, it is 8.5 mA. So, your LED Transformer should be good enough
Today I received the Kemo Rain Sensor, illuburg transformer (even though a 6 W transformer would be enough, thanks @kalle-ol for the measurements, I took 12 W) and Sonoff ZBMINIR2. I did a couple of tests and I’m very satisfied. Now I just have to choose a suitable place for the sensor, make a bracket for it and install everything. My wife will be happy because the rain will no longer wet her window panes and leave stains, because the blinds will be lowered in time.
