Network issues interrupted the transfer.

Could also be that the ESP is crashing (low memory? memory access violation). It’s happened so me when I put stupid code in my sketches haha.

I have the same error

but from what I check it’s related to the esphome connection with HA.
3 of these devices are LibreTiny(beta) devices, and there is a really long delay when I change the light status in HA. while using the webinterface the acction always is instant. If it was a network issue I would assume the webinterface also to have issues but it doesn’t.

The last device is a watermeter which I updated most recently.

It could still be network, but would that explain why the webinterface shows no issues?

5

Out of RAM crashes in the ESP often causes these issues. Webinterface consumes a ton of memory in the ESP.

6

Attach a serial console and watch the logs. Correlate the disconnect you see in HA with what is displayed on the serial console at the time. If you don’t get anything useful increase the logger: level to VERY_VERBOSE and try again
