Hi. I wanted to share a small REST frontend I wrote to integrate readily available wireless sensors to building automation software like OpenHab. I already have several Raspberry Pis laying around the house so the idea was to add a RF receiver module to each of them and build a “wholehouse RF receiver”. I did not want to add new controllers and I did not need to send RF signals. I tried the openhab binding RCSwitch binding, but due to the location of the sensors it was hard to receive codes from all the sensors.
The basic idea behind this project is to start a REST frontend on all the RPis that have a RF receiver and then register REST callbacks (aka webhooks) into OpenHab to change the state of items.
Here is the link to the project
