Hi!
I have the Evohome integration working well and reporting the various temperatures of my zones, and I can turn the hot water on and off from the HASS UI by moving operation
to on
.
However, I can’t work out how to achieve this in an automation. Ideally I’d like to make a switch that I expose in Homekit so I can use Siri to control the hot water.
Here’s how the entity presents:
water_heater.dhw_controller
min_temp: 43.3
max_temp: 60
operation_list:
- auto
- 'on'
- 'off'
current_temperature: 58.9
temperature: null
target_temp_high: null
target_temp_low: null
operation_mode: 'on'
away_mode: 'off'
status:
setpoints:
this_sp_from: '2020-10-07T06:50:00+01:00'
this_sp_state: 'Off'
next_sp_from: '2020-10-07T17:30:00+01:00'
next_sp_state: 'On'
dhw_id: '2653202'
active_faults: []
state_status:
state: 'On'
mode: TemporaryOverride
until: '2020-10-07T17:30:00+01:00'
temperature_status:
temperature: 58
is_available: true
friendly_name: DHW controller
icon: 'mdi:thermometer-lines'
supported_features: 6
Does anyone have any suggestions please?

I was hopeful I might be able to use the Water Heater
service, but this doesn’t seem to work.

Hi @timgp
Does this still work for the EvoHome hot water system? I’ve tried using
action:
- service: water_heater.set_operation_mode
data:
entity_id: water_heater.dhw_controller
operation_mode: 'on'
and
action:
- service: water_heater.set_operation_mode
target:
entity_id: water_heater.dhw_controller
data:
operation_mode: 'on'
but neither actually trigger the hot water. No obvious errors and other calls to the zones work as expected.

Please use the </> button when pasting code. Your automation as pasted is completely broken but might be fine in reality.
I can’t see a water_heater.turn_on
service listed: why do you think this will work?

Fair enough. Does it work as you want if you call it directly from Developer Tools / Services?

No it doesnt for some reason.
Hey,
this is all working great for me now.
This service works
service: water_heater.turn_off
data:
entity_id: water_heater.dhw_controller
I then made these scripts, to use in automations and via Alexa.
