Help needed recording 433Mhz signal : signal recording picks up wrong devices


I am trying to build my first own app by capturing messages from a 433Mhz rainsensor.
So I tried to make use of the 433Mhz recording option in the developer tools as a base to make a signal definition for my new to build app.

At first it looked good because I received a signal and I thought it was the rainsensor and checked the signal in the GTwave analyser app. Hmmm, looked a bit strange as a sort of continious hearthbeat pulse signal, but heck what do I know about what I am doing…:wink:

Then I dropped out my batteries of my rainsensor and still received a signal. That’s strange and makes decoding my rainsensor a lot more difficult. So I tried to move the homey to another place in my house in hope it wouldn’t receive other signals so that I could record a clean signal but unfortunately without luck.

Do any of you have experience or tips for me to capture a clean signal to start decoding and building up signal definition file for my app?

The one thing I can think of: move Homey even further (outside even).
Power Homey using an extension cord, or by using a powerbank, and find a location with the least possible chance of unwanted 433MHz signals by trial.

Your neighbours might have some gear that interferes…

433mhz can travel some distance. I’d probably recommend take it to a friends house.
