Hi all, I couldn’t find anything in the community on this so creating a new topic, any pointers greatly appreciated.
I currently have Google Home voice assistant in my Home Assistant setup, via Nabu Casa, and mostly it works. However, there are a number of sensors that I’d like to have voice control over, but they are marked as “not supported by this voice assistant”, and I don’t understand how to troubleshoot this.
For example, I have a Kitchen Temperature sensor which is supported in Google, e.g. I can say “Hey Google what is the kitchen temperature?”.
However, I would like to expose my blood glucose measurement so that I or my family can say “Hey Google what is Julian’s blood sugar?”. This is provided by the LibreLinkUp integration GitHub - jrsmile/librelinkup: Home Assistant custom Integration for LibreLinkUp. However, the sensor says it is not supported. I wondered whether it was because Google could not interpret the units (mmol/L), so have experimented with template sensors, including one that used degrees centigrade as a unit, and with input_numbers, but none of these are supported.
So, I guess what I’m asking for is, does anyone know what the criteria are for whether a sensor is supported by the Google Assistant integration, suggestions on what I’m doing wrong, or whether there are logs or config files that I can interrogate to try to troubleshoot?
I can provide YAML for the various sensors and/or log entries if of use. Thanks in advance.
Version info: (though I’ve had this issue for around a year across various versions)
In desperation I’ve been looking at the HA source code where this message appears and tagging one of the developers @piitaya – Paul, if you could explain where I could find the logic for why some sensors are unsupported by Google, or point me to some code that might explain it, I would be really grateful.
Thanks for your reply, Paul. I now have it working. TL;DR: to expose a template sensor you need to add a device_class to the entity via the customize: section, in addition to the template definition
Specifically, I’m trying to expose an entity that is measured in mmol/L, and I figured that the units were why it couldn’t be exposed. Therefore, I created a template sensor that exposes the value as a temperature, rather than glucose reading, with the following.
- sensor:
- name: My Glucose As Temperature
unique_id: my_glucose_as_temperature
unit_of_measurement: "°C"
state_class: measurement
state: >-
{{ states('sensor.julian_lawson_glucose_measurement') | float }}
If I look at this sensor in Developer Tools/States, it looks the same as my Kitchen Temperature entity (which is exposed successfully to Google), except for not having a device class:
