@dbemowsk Thank you!

Hello,

I have build the irrigation controler this weekend and just found out that there are some issues using this with domoticz.
Is there someone willing to share his customized code to get these zone and time variables working ?

Thanks in advance,

Edwin

@sundberg84 Thanks, tried but I keep getting false rain tips.

@mfalkvidd thanks, I will look at that thread.

After one night with not a drop of rain ? False tips?

@flopp thanks for the quick reply.

I tried it with your sketch but this gives me a pulse count every time the sensor starts up.
Normaly you do this only once but I think it will do this every hour when synching the time.
I uploaded your sketch 5 minutes ago so I can't confirm this now.

Can someone please share his Raingauge sketch that works with domoticz and is running from an external powersupply 3v or 5v. Trying to get the 'original' to work but it does not work well. It keeps sending rainfall every hour even if it does not rain
I tried the example from @sundberg84 and @TheoL but they have added extra sensor or using batteries.
I am using the latest Mysensors 2.1.1 using esp8266 gateway with domoticz 3.7416.

Thanks Edwin.

@GizMoCuz Nice to see that my old post suddenly comes to live! Thanks for sharing your sketch. It was one of my first builds so it could be the sketch but I also had strange readings using the sample code.
Be cautious with the box you're using. Screws get rusty quick and water leakage will occur!
I have ordered a GYML8511-Uv-sensor-module to try but I will try the old sensor first with your script!

Hello @Mediacj

No I did not find a cause or sollution for the problem. After three broken sensors I gave up.
I will give it a try next summer!
