TO REPRODUCE

Steps to reproduce the behavior: Connect esp8266 to Wi-Fi and wait for a few hours, the device will lose MQTT connection and will reconnect shortly after (turning unavailable in HA).

EXPECTED BEHAVIOUR

A clear and concise description of what you expected to happen. The Device is stable without losing the MQTT connection.

SCREENSHOTS

If applicable, add screenshots to help explain your problem.

ADDITIONAL CONTEXT

Add any other context about the problem here. I have another Tasmota device (13.2.0) which does not experience this problem.

(Please, remember to close the issue when the problem has been addressed)

Those "steps to reproduce" does not. I'm having many ESP8266 devices connected for weeks without seeing any MQTT connection loss, using Tasmota version 14.1.

What router are you using?

sfromis commented 1 month ago

Google Wifi.

Andrei-Iosifescu123 commented 1 month ago

Do you have a mesh system by any chance? I'm using OpenWrt with 2 APs

sfromis commented 1 month ago

Yes, Google Wifi is a mesh system. I have 3 nodes.

bernardesarthur commented 1 month ago

I also have many devices Tasmota like @sfromis and I use UniFi Network here with no problems. No one MQTT Reconnection and no one packet loss. Your problem sounds like a WiFi problem.
