  • You can do a few things to reduce interference if the device broadcasting the signal supports it. Unifi APs support these settings. Most routers with WiFi probably do not support transmit power.

    1. Adjust transmit power to lower setting
    2. Higher the frequency, shorter the range (but that frequency may be highly used in the area), so #3 is the better option
    3. Analyze the frequency usage and picking a frequency that is least used
    4. If 2.4Ghz band isn’t necessary disable it and only use 5Ghz since it’s a higher frequency it again has a lower range.
    5. You could also faraday cage your room so the signal won’t leak out, but thats probably more work than its worth.










  • I have this setup and using the esp my stack device mentioned in the article. The biggest problem with it is esphome and home assistant expect home assistant to be running in a dedicated device for this to work. The integration uses a random UDP port to communicate with the M5 stack device. I had to resort to patching the Integration to use a couple specific ports to work properly.

    Unfortunately the fix didn’t last long and a update to home assistant updated the integration and now the text to search response fails for esphome devices. My next plan is to try to downgrade esphome integration to the old one that was patched / working and call it a day.
