Just sharing my template for setting boiler demand based for a group of ‘Better Thermostat’ devices.
I use this to turn my boiler on when any of the thermostats calls for heat, and off when none of them do.
note: I don’t think both the ‘temp < requested’ and ‘mode = heating’ are required, but it works fine with them both in.
template:
- binary_sensor:
- name: "Heat Demand"
unique_id: boiler_demand_group
#state: "{{ integration_entities('better_thermostat') | expand | selectattr('attributes.hvac_action','eq','heat') | list | count | float(0) > 0 }}"
state : >
{% set BTStats = integration_entities('better_thermostat') | expand %}
{% set climates = namespace(under=[]) %}
{% for BTStat in BTStats %}
{% if BTStat.attributes.current_temperature < BTStat.attributes.temperature and BTStat.attributes.hvac_action == 'heating' %}
{% set climates.under = climates.under + [ BTStat.entity_id ] %}
{% endif %}
{% endfor %}
{{ climates.under | length > 0 }}
