Connectivity issue question

[jorkzijlstra]

I trying to connect with a new device and that seems to fail on some sort of connectivity issues and was wondering if you might know what these are or how I can mitigate them.

At first it does connect and work but it fails after seconds or minutes. The network signal of the device is a 100%. I have already tried to reduce the interval from 15 to 30 seconds but they still persist.

The ESP code is this: https://github.com/gekkekoe/esphome-ecodan-hp Within HA there doesn't seem to be an issue reading the data

The errors

try to remove encryption in api section and use password

[jorkzijlstra]

Sorry for the late reply but I was on holiday. I'm trying this change now.

[jorkzijlstra]

It seems that after I upgraded node-red to 3.1.3, this plugin to 0.2.8 and the device to esphome 2024.7.3 everything became stable again even when using the encryption key.

Not sure which component was actually the fix though
