Hey guys,
I am trying to build an automation to cycle through a list of WLED presets on a remote button press, which I get via select.wled_preset.
I have built 2 templates for this with an input_number that stores the index of the currently selected preset to determine which is the next one. One gives me the new option name and the other the new index.
Setting the new index into the input_number via the input_number.set_value service also works without problems, but I can’t change the WLED preset this way:
Error: Option {{ states('sensor.wled_sofa_next_template_string') }} not valid for Preset
The sensor gives me a matching string which I can select manually in the options
This is my sensor code for getting the new string (new index sensor is basically the same except that it returns only nextOptionIndex):
- sensor:
- name: 'WLED Sofa nächste Vorlage String'
state: >
{% set presetList = state_attr('select.wled_sofa_preset', 'options') %}
{% set presetListLength = presetList | length | int(0) %}
{% set currentPresetIndex = states('input_number.sofa_dimmingswitch_presetvalue') | int(0) %}
{% set presetIndexAddiert = currentPresetIndex+1 %}
{% set nextOptionIndex = presetIndexAddiert if presetIndexAddiert < presetListLength else 0 %}
{{presetList[nextOptionIndex] if presetListLength > 0 else "KEINE VORLAGE VORHANDEN" }}
availability: >
{{ presetListLength > 0 }}
which returns something like “Dunkelblau” or “Leselicht” without the quotes
and this is the automation part:
alias: Ambilight Sofa Szenenwechsel

As a HA newbie I just don’t know what else I could do so help would be awesome
