Im on Domoticz since 2015. Running with Mysensors, Rflink(433MHz sensors), HA-Bridge (Amazon Echo), Broadlink (IR, 433MHz). Iwas looking at HA months ago - UI looks better, but then I installed Dashticz and my only problem was solved :)

Most of these cheap sensors are based on PT2622 chip or similar. RF link works fine with them.

Thanks Guys!
I have edit the sketch and modified the sensor. Records made during night are finally closer to real situation. I need to correct pulse count.
@karlheinz2000 - are you using digital or analog output as on FHEM forum? (Danke, fuer Deine Anweisung)

+1 for RFM(433Mhz)
I´m already running NRF and keeping it (have build many nodes on it). But, for example I have a garage (steel structure with sheet-metal paneling) and its ca.6 meters from NRF gateway - no signal! Same distance RFlink (433Mhz) works just fine.

Oh thanks everybody, I'll try it today.
