Hello,
I’m just starting out with ESPhome programming.
I’m trying to pass a parameter to a script.
This script, “check_heaterLevel_upDown,” is supposed to compare the passed value “levelNow” with the global variable “heat_level_now” to see if the value is above or below the current level.
I was thinking of using on_value_range.
script:
- id: check_heaterLevel_upDown
parameters:
levelNow: int
then:
- on_value_range:
above: !lambda id(heat_level_now);
script.execute: calc_minRunTimeInHeatLevel
script.execute: heaterLevel_minus
below: !lambda id(heat_level_now);
script.execute: calc_minRunTimeInHeatLevel
script.execute: heaterLevel_plus
This code also seems to be incorrect.
script:
- id: check_heaterLevel_upDown
parameters:
levelNow: int
then:
- on_value_range:
above: !lambda id(heat_level_now);
- script.execute: calc_minRunTimeInHeatLevel
- script.execute: heaterLevel_minus
below: !lambda id(heat_level_now);
- script.execute: calc_minRunTimeInHeatLevel
- script.execute: heaterLevel_plus
But no matter what I do, I get an error message saying my syntax is incorrect.
mapping values are not allowed here
in "/config/esphome/test1.yaml", line 184, column 25
Can anyone help me with this?

Attempt at an explanation of the code:
What I want to achieve with the code:
It’s about controlling a slow-reacting diesel garage heater that often has a temperature difference of about 15°C between the actual and target temperatures when first switched on.
The heater has exactly 10 heating levels and starts at the highest level, 10, after every restart.
So, before I can regulate the heater using temperature measurements and try to maintain the target temperature, the heater first needs to run for a specific, predetermined time at a particular heating level.
If I don’t do this, the heater would just keep switching back and forth.
Therefore, I need temperature differences and switching times.

Actually - I didn’t need your yaml - Sunday arvo has fuzzed my brain and I didn’t notice that on_value_range: isn’t valid for scripts.
You need to test the parameter value in lambda - for example:
script:
- id: check_heaterLevel_upDown
parameters:
levelNow: int
then:
- if:
condition:
lambda: 'return levelNow >= id(heat_level_now);'
then:
script.execute: calc_minRunTimeInHeatLevel
script.execute: heaterLevel_minus
etc...

Thank you,
I just wasn’t sure if I had the wrong syntax or if on_value_range simply doesn’t work in the script, since I’ve only ever seen on_value_range used in Sensor and, I think, Number functions as examples.
I’ve now solved it with lambdas and if statements.
However, the syntax and notation you have to use in ESPHome is really quite confusing at times.
For example, the compiler doesn’t throw an error during the initial code check when you call execute under lambda, but after it’s almost finished compiling, it finally throws the error that it doesn’t like the execute command.
code snipped:
script:
- id: check_heaterLevel_upDown
parameters:
levelNow: int
then:
lambda: |-
if(id(heat_level_now) > levelNow){
//id(calc_minRunTimeInHeatLevel).execute();
if(id(heat_level_now) > levelNow){
id(heaterLevel_minus).execute();
}
};
if(id(heat_level_now) < levelNow){
//id(calc_minRunTimeInHeatLevel).execute();
if(id(heat_level_now) > levelNow){
id(heaterLevel_plus).execute();
}
};
