Z-Wave device reporting Fahrenheit, but UOM showing as Celcius with an explicit "Home" zone

Configuration

I just updated to 0.88.2, but I can’t be sure if that caused this behavior so I wanted to post first before filing an issue. I have a Z-Uno board with a DS18B20 temperature probe and it’s reporting temps in Fahrenheit, confirmed by looking at the Open Z-Wave log. With the default zone (no explicit “zone:” component in configuration.yaml), and with “unit_system: imperial” specified, I see the correct “℉” in “unit_of_measurement” in the states view and elsewhere. If I simply add the “zone:” tag in configuration.yaml, it’s reported as Celcius everywhere. Here’s a snippet of configuration.yaml that correctly reports in Fahrenheit:

homeassistant:
#zone:
  # Name of the location where Home Assistant is running
  name: Home
  # Location required to calculate the time the sun rises and sets
  latitude: xxx
  longitude: xxx
  # Impacts weather/sunrise data (altitude above sea level in meters)
  elevation: 340
  # metric for Metric, imperial for Imperial
  unit_system: imperial
  # Pick yours from here: http://en.wikipedia.org/wiki/List_of_tz_database_time_zones
  time_zone: America/Los_Angeles

With this, the unit_of_measurement switches to “℃”:

homeassistant:
zone:
  # Name of the location where Home Assistant is running
  name: Home
  # Location required to calculate the time the sun rises and sets
  latitude: xxx
  longitude: xxx
  # Impacts weather/sunrise data (altitude above sea level in meters)
  elevation: 340
  # metric for Metric, imperial for Imperial
  unit_system: imperial
  # Pick yours from here: http://en.wikipedia.org/wiki/List_of_tz_database_time_zones
  time_zone: America/Los_Angeles

Am I missing something? Incidentally, I’m only interested in adding the “zone:” tag to be able to specify a radius of larger than 100M for Device Tracker, and it seems strange that that tag is only allowed with an explicit zone while the others are all valid in the default zone.

Yes, you’re changing the entire homeassistant section into a zone, effectively removing the homeassistant section. You need to override the home location in a SEPARATE zone location.

homeassistant:
  # Name of the location where Home Assistant is running
  name: Home
  # Location required to calculate the time the sun rises and sets
  latitude: xxx
  longitude: xxx
  # Impacts weather/sunrise data (altitude above sea level in meters)
  elevation: 340
  # metric for Metric, imperial for Imperial
  unit_system: imperial
  # Pick yours from here: http://en.wikipedia.org/wiki/List_of_tz_database_time_zones
  time_zone: America/Los_Angeles

zone:
  # This will override the default home zone
  - name: Home
    latitude: 32.8793367
    longitude: -117.2474053
    radius: 100

I see, thanks! When I saw that I’d just be duplicating those entries, I thought I could “optimize” it :).

Edit: All better now.
