Configurator not working

[Ancalgon]

Hi guys, I have a problem.
Till few days ago the configurtion plugin was working like a charm, from yesterday (no updating anything) every time I start the UI to configure the zones, I get and error:

Error executing template: Failed to execute template

In the logs I can see:

`s6-rc: info: service fix-attrs: starting
s6-rc: info: service fix-attrs successfully started
s6-rc: info: service legacy-cont-init: starting
s6-rc: info: service legacy-cont-init successfully started

services-up: info: copying legacy longrun nginx (no readiness notification)
s6-rc: info: service legacy-services successfully started
ERROR:root:Running as a Home Assistant Add-on.

• Debug mode: off
  ERROR:root:Failed to execute template. Status Code: 400
  ERROR:root:Response: {"message":"Error rendering template: Template output exceeded maximum size of 262144 characters"}`

The device is working, I had done a reset, I had tried also to create a docker on my server and connect to my home assistant but the error and the logs are identical

Other details:
ESPHome 2024.11.3
Device is not visible

Did you change the name of the device?

[Ancalgon]

Yes the first time that I'd used the device, months ago. But the addon has worked for the first few days and then suddenly I've got the error. I had tried to to a backup of Home Assistant, roll-back to the day before I've installed the plugin and to install it fresh on the system, same problem from the first run. Of course was an experiment so I had rollforward to the newest backup.
But the sensor it self is working, something is strange because i had loosed all the zones data.

Nothing, I had reset another time my EP Lite, reinstalled the firmware, configured the wifi and exposed all the sensors. I had reinstalled ESPHome, remove any custom name but nothing. The configurator is not working and I really don't know how to solve the problem. The sensor itself is working

Does it find the name of the device but doesn't work after that or does it not show the device in the drop down at all?

[Ancalgon]

The configurator does not show any device. In home assistant the device hasn't any custom name, just the default one.

Can you share the ESPHome diagnostics by going to the device page in home assistant, click the 3 dots and download ESPHome diagnostics

I have tried to install the configurator as Home Assistant addon, as VM and LXC in Proxmox and as docker on Unraid. The Error is always the same. Interesting I get the error even if I don't give the home assistant ip. It happened inside the Unraid docker. And when I've configured the docker with the IP of my home assistant, for a brief moment something happen only to refresh the page after a second and end in the same popup error
