Sensor DHT-11

@arduino_89_89 said in Problem with Domoticz: Hi everyone, I wanted to know how ever whenever the PC reboots, I also change the com port. And why when I break the gateway, are the sensors no longer connected? What environment? Could this help? https://www.domoticz.com/wiki/Assign_fixed_device_name_to_USB_port

Not sure if this will help, but some time back I built a motion sensor setup to control a flood light for my driveway. The node has a lux/LDR sensor for light/dark, relay and a motion sensor. The idea with that node was that the light would turn on if motion was detected and if it was dark enough. You mat be able to go through the code and take out the motion sensor parts and just use the light sensor and relay code. Here was my writeup on the project. https://forum.mysensors.org/topic/5243/driveway-motion-light

I followed the Mq2 Sensor Tutorial, but I'm only out of the kids and not on devices. Instead, for the rain sensor I did not find anything.
