Signal strength analyzer

Is there an android app for testing the seperate signals of the homey? There are a lot of wifi testers, but I would like to know how far a zigbee or 433mhz signal is reaching of the homey itself.

Your android device doesn’t have a 433 or Zigbee radio so no…

Off course, off course. I should have figured this out myself.
Is there any other way?

It is not so obvious as I check the websites

I guess it wil be by try & error.

Or look for a dvb-t USB stick you maybe already have or buy one on internet for Les than 25 € and use one of the many SDR applications like
