Gotta say I love OpenHab! I have been slowly converting our house to be as smart as possible and I love not be trapped by a specific product or protocol. Recently I have started exploring building custom sensors as I have not been very satisfied with some of the different multi-sensors I have trie…

Good morning, have a look at mysensors.org

… or take a look at ESP8266 wifi modules and use it with mosquitto broker and mqtt binding in oh.

[image] sihui: … or take a look at ESP8266 wifi modules and use it with mosquitto broker and mqtt binding in oh. Second using these as the ESP8266 modules have built-in wifi and work great. If you do try these, don’t use the latest IDE from Arduino for programming, your sketches won’t compile…

If you plan on making several sensors, I’d advise MySensors.org as well. If it is only for one sensor, implementing a gateway just for that one sensor would be a bit much though… What’s great with mysensors is that it’s a mesh network, not a star network. So your sensor outdoor could talk with a s…

Thanks for all the replies! I actually have a couple ESP8266’s and Arduino Uno’s. I already have mqtt broker up and running on my RasPi too. The only thing that has stumped me with the ESP8266 is from what I have read the need to change the tx/rx pins down to 3.3V. Which to me is kinda strange…

@naturalblaze - I’ve made a couple of the ones shown here , the DHT22 sensors were shown farther up in that same thread and come on a board with a capacitor and resistor. It is connected to 3V3, GND and D4 when looking at this diagram . And the board itself is powered by a 5V wall plug. @anthony_ma…

Personnaly, for connectivity of my sensors, I chose 2,4GHz because of the very low cost of these modules (less than 1€). This is not wifi, just direct RF between the sensors and my gateway. The mesh nature of the network is a functionality I don’t use now, but I would if I had a house. It enables y…

Come take a look at our DIY Home Automation with OpenHAB & RFM69 radios We mostly use Arduino compatibles for the sensor / control nodes, but OpenHAB often runs on a Raspberry Pi

Thanks for the follow-up. That type of mesh network is how I cover my house/property with wifi using http://www.open-mesh.com/ , so I have wifi everywhere.

I’d like to check that out. Can you share the sketch you have to upload to that?

Raspberry Pi or Arduino custom sensors?
