Home Assistant reporting: "Template variable warning: 'off' is undefined when rendering '{{value_json.hc1['cooling'] if value_json.hc1 is defined and value_json.hc1['cooling'] is defined else off}}'"

[timostr]

I've got in my Home Assistant logfile many warnings:
Template variable warning: 'off' is undefined when rendering '{{value_json.hc1['cooling'] if value_json.hc1 is defined and value_json.hc1['cooling'] is defined else off}}'

Is this a problem in the ems_esp code?
Is there anything I can do to solve this issue?

System Information:

• HomeAssistant:
  -- Core 2024.10.4
  -- Supervisor 2024.10.3
  -- Operating System 13.2
  -- Frontend 20241002.4

ems-esp:
-- version": "3.7.1-dev.1

[proddy]

this has been fixed I think in a later dev version, try dev-3

Tried dev-3 - However the problem is still there:

Logger: homeassistant.helpers.template

Template variable warning: 'off' is undefined when rendering '{{value_json.hc1['cooling'] if value_json.hc1 is defined and value_json.hc1['cooling'] is defined else off}}'

I've noticed several entities in home assistant with state "unavailable":

oh. Could you use MQTT Explorer and paste the contents of these topics, so I can reproduce :

• ems-esp/thermostat_data
• the config topics under homeassistant/ which have raise and cooling in the name. Use search

thanks

[timostr]

Note: I updated to dev-4 and the same problem.

Can you help me to provide the "config topics" under homeassistant? Are you referring to all files in the config folder of home assistant with raise or cooling in it ????

I could offer as well a screen sharing session with you. Thank you so far!

use MQTT Explorer (https://mqtt-explorer.com/) or anything similar to see what's in the MQTT broker.

I've cleaned the MQTT broker by following the instructions here: https://github.com/swa72/home-assistant/blob/main/README-mqtt.md
I.e. removed everything from homeassistant/*/ems-esp

This has solved my problem!
