Unfortunately I created this post in German at first. Now here is the translation to English:
I created this sensor to report the daily PV-yield (Tagesertrag) in kWh.
The source provided by the SMA integration is in Wh.
tagesertrag:
unique_id: "sensor_tagesertrag"
friendly_name: "Tagesertrag"
unit_of_measurement: "kWh"
value_template: "{{ (states('sensor.sn_3001234053_daily_yield') | float / 1000) }}"
When I use the sensor on the Dashboard, 54,123 kWh is shown correctly (European format) with the “,” as decimal separator.
But when I issue the value with this code …
message: "Todays yield is {{ states('sensor.tagesertrag') | float }} Kilowatthours"
action: notify.alexa_media_last_called
… on Alexa, it says:
“Todays yield is 54123 Kilowatthours” (54thousandonehundredtwentythree) … ignoring any decimal separator.
If I change the code to …
message: "Todays yield is {{ states('sensor.tagesertrag') | float | round(1) }} Kilowatthours"
… Alexa says:
“Todays yield is 54.1 Kilowatthours” (54 point 1)
Only if I add the replace instruction …
message: "Todays yield is {{ states('sensor.tagesertrag') | float | round(1) | replace('.', ',') }} Kilowatthours"
… it is reported correctly using a comma as separator :
“Todays yield is 54,1 Kilowatthours” (54 comma 1)
Why is the comma shown on the dashboard, then ignored and later replace by a point?
This is pretty confusing and looks inconsistent.
Or am I doing something wrong?
