Hallo!
Habe 2 batteriebetriebene Sensoren (Zigbee), die jeweils Temperatur und Luftfeuchtigkeit messen. Die Sensoren liefern nicht dauernd Werte, sonder nur sporadisch, insbesondere, wenn sich die genannten Werte ändern. Ansonsten sind sie offline, haben also “Nicht verfügbar” als Status. Nun habe ich 4 virtuelle Sensoren in template.yaml angelegt, die den letztgemeldeten Wert des physischen Sensors melden, falls dieser grade keinen Wert meldet. Der Syntax der 4 virtuellen Sensoren ist exakt gleich, bei 3 der 4 Entitäten funktioniert das prima, aber einer wird gar nicht angelegt, weil HA an der Syntax-Logik meckert.

{% set sensorstatus = states('sensor.zigbee_ths_kizi_temperatur', 'raw_state') %}
{% if sensorstatus != 'unavailable' %}
{% set valuetokeep = sensorstatus %}

{% else %}

Und hier die Fehlermeldung im Log:

The above exception was the direct cause of the following exception:

raise ValueError(
ValueError: Sensor sensor.kizi_temp_permanent has device class 'temperature', state class 'measurement' unit '°C' and suggested precision 'None' thus indicating it has a numeric value; however, it has the non-numeric value: 'valuetokeep' (<class 'str'>)
Es wird bemängelt, dass der Sensor einen non-numerischen Wert haben sollte, was er bei “unavailable” aber nicht hat. Deswegen kann HA die Variable valuetokeep nicht in eine float umwandeln. Klingt ja logisch, aber warum funktioniert es bei den anderen 3 Sensoren ohne Probleme?
. Ein kleines “r” vergessen. Jetzt funktioniert es:innocent:.
