After some hours/days fauxmoESP device doesn't react to Alexa anymore #162

Hello,

I have setup everything in a way that it works with Alexa and I can control my ESP8266 with fauxmoESP. So thank you for the great work1

However, after some hours or even days, Alexa doesn't find the device anymore - "please check your network connection" etc.

Is there any sleep mode or something? Is this a know problem? What could I do to prevent it?

Best Regards

It could be several things.

Can you still ping the device? That would indicate wireless issues which would be my first guess. As a workaround you could restart the device when you don't need it (at night?) or implement a wifi reconnection function. I've never had issues with devices disappearing so I'd start looking other directions.

I had the same problem with one WiFi network about a year ago (I don't recall what type of router it was). On other networks they seem to stay connected for a long time with the same code.

Devices would run for a day or so, then unreachable. I tried a few things to detect when it had lost connection, but was not able to sort it out.

What I ended up doing was using ESP32-Ping (there's an ESP8266Ping library too, but haven't tested it). I set it up to ping the router once every 15 minutes, and if it could not reach it, disconnect the WiFi, reconnect, and try again.

The behaviour has not repeated since I have written the above message. :-)

I will try next time to ping the device and eventually implement that 15min ping. Thank you for your answers.
