regarding the polling: yes, with this rain sensorrain sensor, I want an immediate alarm when it starts to rain. e.g. to close some windows automatically. That’s why the short term polling. Sorry for mixing it up in this thread.
(this sensor will be sn2)
Regarding the second sensor (rain gauge), i would also say: 5 minutes is sufficient.
(this sensor will be sn1)
Would it be possible to reset the value of sn1 manually? (e.g. everyday at 12am)
When tracking the amount of rain water with the rain gauge, it would be easier to display that in graphs.
Thanks again for your great support – I really appreciate that 🙂
