Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

Changed

  • Register 3 has been changed from type sensor to number to make them configurable

[5.1.0] - 2025-01-12

Added

  • Active State Map: A sensor that represents the state as a number. This can be used for example in Grafana to plot a state time timeline
    • 0: Inactive, 1: Heating, 2: Cooling, 3: DHW, 4: Defrosting, 99: Unknown (no mapping found)

Removed

  • Register 4 sensor entity removed and now only present as number

[5.0.0] - 2024-11-24

Changed

  • Add COP - heat pump efficiency factor
    • Be aware that the energy metering is not acurate at all, therefor do not trust the COP from this sensor
  • Update registers
    • 2: min/max value with verifing depending emmision type settings
    • 3: min/max value range
    • 4: min/max value range
    • 103: convert valve open position to percent representation
    • 101: moved to text sensor with status
    • 200: moved to text sensor with home appliance decode value code to text names
    • 211: completely configurable except reserved values
    • 210: completely configurable except reserved values
  • Built-in web frontend change from CSS v2 to v3

[4.1.2] - 2024-10-16

Changed

  • Update Register: 5 to be fully configurable

[4.1.1] - 2024-10-15

Changed

  • Update Register: 0 to be fully configurable

[4.1.0] - 2024-10-12

Changed

  • Added icons to all entities, code provided by rysiulg

[4.0.0] - 2024-10-04

Changed

  • esp-idf is used as ESP32 framework instead of arduino (breaking change)
    • This framework is recommended for ESP32 chips by ESPHome. Be aware that this is a breaking change. To apply this configuration update on an existing board, an one-time serial flash will be needed
  • Removed "ssid" and "password" from the wifi section. These will be stored by the captive portal component
  • Renamed "Power Air Conditioner Zone 1" to "Room Temperature Control", "Power Floor Heating Zone 1" to "Water Flow Temperature Control Zone 1" and "Power Air Conditioner Zone 2" to "Water Flow Temperature Control Zone 2"
  • Removed "${entity_prefix} from all entries. Got a tip from user "Septillion" on https://tweakers.net that this is not needed (anymore?) in ESPHome (breaking change (potential))
    • If needed, ESPHome will add the "friendly name" to an entity, which is "Heatpump Controller" in the current configuration.

Fixed

  • "Active State" now also takes into account when the temperature is controlled by the water flow temperature and not only the room thermostat

[3.2.1] - 2024-10-01

Changed

  • 'Electricity Consumption' and 'Power Output' configured as device class 'energy'

[3.2.0] - 2024-08-05

Changed

  • Add value "T1S DHW", which is the T1S value when in DHW mode (TS1 DHW = T5 + dT1S5)

[3.1.0] - 2024-06-30

Changed

  • Register 0: Bit 0, 1 and 3 changed from binary sensor to switch to make them configurable
    • Bit 0: Power Air Conditioner Zone 1
    • Bit 1: Power Floor Heating Zone 1
    • Bit 3: Power Air Conditioner Zone 2

[3.0.1] - 2024-06-23

Fixed

  • ESPHome version 2024.6.0 requires a platform key under ota

[1.0.1] - 2024-01-13

Fixed

  • Changed some temperature sensor value types from a unsigned integerer to a signed integer. Which this fix, potential negative values are displayed as they should instead of displayed as very high positive values.

[1.0.0]

Added

  • Sensor that shows if the heatpump is running.
  • Fault to Error code mapping overview.
  • Mapping from fault to error code and from current fault to error description.
  • Heatpump status.
  • Homeassistant dashboard and automations.
  • Uptime.
  • Key friendly_name, enabled the web server and add api.encryption.key.
  • Switch for register 0 bit 2.

Fixed

  • DHW Tank Temperature T5s can be set between 20 and 60 degrees, instead of 40-60 what the docs state.
  • Condenser temperature is a signed value.
  • Fix bitmask for register 0 / bit 1.
