Hive TRV Boost Mode

AppDaemon app to mimick the behaviour of boost mode on your Hive Radiator Valves.

In order to keep heating to a minimum, installing smart radiator valves is the first bit, however you can trigger heating for specific rooms depending on the temperatures set for your radiator valves. This will also stop heating once the target temperature is reached.

This assumes you are using Zigbee2MQTT to connect to your Hive Heating thermostat.

Devices used

• Hive Thermostat SLR1b
• Hive UK7004240 Radiator Valve

Installation

Use HACS or download the heating directory from inside the apps directory here to your local apps directory, then add the configuration to enable the heating module.

App configuration

heating:
  module: hive_trv_heating
  class: HiveHeating
  main_thermostat: climate.living_room_thermostat
  main_thermostat_zigbee_set_topic: "zigbee2mqtt/Living Room Thermostat/set"
  trv_list:
    - climate.office_radiator_valve
    - climate.main_bedroom_cove_radiator_valve
    - climate.main_bedroom_radiator_valve
    - climate.hallway_radiator_valve
    - climate.second_bedroom_radiator_valve
  log: heat_log
  trv_boost_mode: input_boolean.trv_heating_boost_mode
  trv_boost_mode_temperature: input_number.trv_boost_mode_temperature
  boost_mode_hold_duration_minutes: 35

key	optional	type	default	description
module	False	string		The module name of the app.
class	False	string		The name of the Class.
main_thermostat	False	string		The entity in home assistant referring to your main Hive thermostat.
main_thermostat_zigbee_set_topic	False	string		The MQTT set topic referring to your main Hive thermostat.
trv_list	False	list(string)		The list of TRV entities which you would like to have the app monitor for boost mode.
log	True	string	heat_log	The log in appdaemon to write the logs to. It's suggested you create a log specific to this to separate logging.
trv_boost_mode	False	string		The input_boolean entity to control this app, enabling or disabling boost mode.
trv_boost_mode_temperature	False	string		The input_number entity to determine what is the maximum boost mode value the main_thermostat should be set at.
boost_mode_hold_duration_minutes	False	string		The amount of minutes that boost mode should be kept on with a single message. This is there so that if the app fails, then boost mode would only be on for at most 35 minutes.

Appdaemon yaml

In order to set the logs output, add this log entry to your appdaemon.yaml file. If you do not add it, it will default to the default log output.

logs:
  heat_log:
    name: HeatLog

Logic of Application

This app will use the hvac_action set in each Hive radiator valve, it probably can be used with other TRV's to interact with the Hive emergency boost feature. Once the radiator valve requires heat, it will set it's hvac_action attribute to heating. heating Triggers this appdaemon to push an emergency boost message to the main Hive thermostat. If the app is restarted or unexpectedly crashes, it will check if heating is required on a minute by minute basis just to ensure that no excess heating is done to save on costs.

You can set automations which will disable this app by setting the trv_boost_mode variable to False by changing the input_boolean provided.
