#  Package to manage your carheater at winter
# Packaged by @Naesstrom
# Original Repo : https://github.com/gribber/ha
# Required components etc.
#  - SMHI weather component (or any other weather component that gives a upcoming low value)
#  - Either a single device tracker for you or even better a group of trackers.

Where did you get the package?

You have given no logs or other symptoms of whatever problem you are seeing.

In the top is an adress for the package, its doing nothing…
A found a log could it be this:

TemplateError(‘UndefinedError: ‘None’ has no attribute ‘attributes’’) while processing template ‘Template("{% if states.sensor.time.state < states.sensor.heater_departuretime.state and states.sensor.time.state > ‘00:00’ %} {% set forecast = states.weather.smhi_home.attributes.forecast[0].templow %} {% else %} {% set forecast = states.weather.smhi_home.attributes.temperature %} {% endif %} {{ forecast }}")’ for attribute ‘_state’ in entity ‘sensor.heater_forecast’

Found a never version in the adress, thanks anyway
