HomeWizard Energy


Integration for the HomeWizard Energy platform. It can collect data locally from the HomeWizard Energy products and create them as sensors in Home Assistant.

Supported devices

  • Wi-Fi P1 Meter: Depending on the connected DSMR meter: sensors for power import/export, energy consumption (single or three phases) and gas. (Model: HWE-P1)
  • Wi-Fi Energy Socket: Sensors for power import/export and energy consumption and switches for controlling the outlet (model: HWE-SKT)
  • Wi-Fi Watermeter: Sensors for active and total water usage (model: HWE-WTR)
  • Wi-Fi kWh Meter: Sensors for power import/export and energy consumption. (Models: SDM230-wifi, SDM630-wifi)

The Wi-Fi Watermeter can be powered via a USB-C cable and with batteries. When using batteries they only connect to Wi-Fi every couple of hours. Because of this, the API can only be used when powered via the USB-C cable. It is not possible to add use this integration when the water meter is powered by batteries.

Enable the API

You have to enable the local API to allow Home Assistant to communicate with your device. Do this in the HomeWizard Energy app:

  1. Go to Settings. (Gear icon in the upper-right)
  2. Go to ‘Meters’.
  3. Select your device.
  4. Scroll down and turn on ‘Local API’.

Configuration

Adding HomeWizard Energy to your Home Assistant instance can be done via the user interface, by using this My button:

HomeWizard Energy can be auto-discovered by Home Assistant. If an instance was found, it will be shown as “Discovered”, which you can select to set it up right away.

Manual configuration steps

Sensors

The HomeWizard Energy API only exposes properties that are used within the HomeWizard Energy app. The available properties are listed below.

Name Unit Availability Description
Wi-Fi SSID HWE-P1, HWE-SKT, HWE-WTR, SDM230-wifi, SDM630-wifi The SSID of the connected network.
Wi-Fi strength % HWE-P1, HWE-SKT, HWE-WTR, SDM230-wifi, SDM630-wifi Percentage of the Wi-Fi connection.
Total energy import T1 kWh HWE-P1, HWE-SKT, SDM230-wifi, SDM630-wifi Energy import reading.
Total energy import T2 kWh HWE-P1 Energy import reading for other tariff.
Total energy export T1 kWh HWE-P1, HWE-SKT, SDM230-wifi, SDM630-wifi Energy export reading.
Total energy export T2 kWh HWE-P1 Energy export reading for other tariff.
Active power w HWE-P1, HWE-SKT, SDM230-wifi, SDM630-wifi Active power usage.
Active power L1 w HWE-P1, HWE-SKT, SDM230-wifi, SDM630-wifi Active power usage line 1, for SDM230-wifi andHWE-SKT this value is the same as Active power.
Active power L2 w HWE-P1, SDM630-wifi Active power usage line 2.
Active power L3 w HWE-P1, SDM630-wifi Active power usage line 3.
Total gas m3 HWE-P1 Current gas import reading, only available when your smart meter is connected to a gas meter.
DSMR version HWE-P1 The detected DSMR version.
Smart meter model HWE-P1 The detected smart meter model.
Active water usage liter per minute HWE-WTR The current usage of water.
Total water usage m3 HWE-WTR Total of water measured since installation.

Switches

The Wifi Energy Socket (HWE-SKT) outlet state can be controlled the switch platform. There are two switches:

  • Switch: Controls the outlet state of the Energy Socket. This switch is locked out when Switch Lock is turned on.
  • Switch lock: Forces the outlet state in the on position and disables the physical button. This option is useful when the socket is used for a device that must not be turned off, such as a refrigerator.
