Lambda and Dallas temp

ESPHome
#1

I don’t know why its error after error but, its driving me nuts. I’m just trying to see if temp1 < temp2 - variable.

For the global values try .value or .value() instead of .state.

Not sure what is going on with the Dallas, can you post the yaml config for those?

#3

For starters - for single line lambdas it is good practice to enclose them in quotes - e.g:

          - lambda: 'id(standby_mode).publish_state(true); '

id(supply_air_temp).state should work fine, so yes - post the sensor config.

yes, thanks.

here is all of it if that helps or if anyone has critiques or suggestions I can improve on.

I think the id used for the lambda to get the temperature reading should be with the temperature configuration and not the dallas bus configuration.

It throws an error when trying to split them up with different ID’s you cant see it in the screen shot but I changed the dallas id like your suggestion

It looks like changing the id: around is a quirk or bug in the user interface. I got the same warning when making the change in the editor but disappeared after a HA restart.

To access the global values just the id(global) is all that is needed, no .state or .value necessary.

The below configuration compiles for me on 2022.11.1. I made one other fix to the template select lambdas.

globals:
  - id: ac_deg
    type: int
    restore_value: yes
    initial_value: "4"

  - id: heat_deg
    type: int
    restore_value: yes  
    initial_value: "4"
