Home Assistant integration of the Ablemail ABB-07

The Ablemail ABB-07 (ABB07) is a serial to bluetooh device for communication with their chargers. See their website for the products compatible with the ABB-07 https://ablemail.co.uk/. They provide an app for IOS and Android for readout and adjusting settings.

This Home Assistant integration is only for readout and has been tested on the AMT12-2 Tickle charger.

The integration provides all available sensors from the ABB-07 / charger, depending on the type of charger attached not all the sensors will provide a valid output:

• abb07_liv: Local Input Voltage
• abb07_riv: Remote Input Voltage
• abb07_lov: Local Output Voltage
• abb07_rov: Remote Output Voltage
• abb07_li: Local current
• abb07_mt: Microcontroller Temperature
• abb07_ft: Mosfet Temperature
• abb07_rt: Remote Temperature
• abb07_vtrgt: Target Voltage
• abb07_vfloat: Float Input Voltage
• abb07_vboost: Boost Input Voltage
• abb07_runningtime: Time in seconds the charger has run (provided current between input and output)
• abb07_runningtime: Uptime of the charger in seconds

Requirements

• Bluetooth device set to passive scanning in Home Assistant.
• Low power mode of the charger disabled, as the wake-up call isn't implemented.

Installation

Open a terminal in Home Assistant and git clone this repository in ~/config/custom_components/abb07

git clone https://github.com/skleijkers/abb07 ~/config/custom_components/abb07

Add the following lines to the configuration.yaml of Home Assistant:

abb07:
  device: "XX:XX:XX:XX:XX:XX" # Identifier of ABB-07 bluetooth module (MAC address layout)
  keep_connected: False # Keep the connection to the ABB-07 open or close it after each request (optional, default: False)

Setting the bluetooth device in Home Assistant to passive scanning

• Open your Home Assistant.
• Go to Configuration -> Devices & services.
• Click on Bluetooth (for further configuration of the bluetooth integration).
• Click on Configure link.
• Check the Passive scanning and click on Send.

Disable the low power mode on the ABB-07

• Open the Ablemail Device Manager for Android or IOS on your phone.
• Connect to the ABB-07 (while in reach of the device and after the device has just been powered on).
• Go to Device Settings and change the Low Power mode to Disabled.
• Send the settings to the device.

Warning

After changing the mode setting of the charger, the device settings are reset to the default and the Low Power mode is enabled again.

Documentation

keep_connected option

Default the keep_connected option is set to False, thus opening and closing the connection to the ABB-07 on every request for sensor data. In this mode it's possible to use the app alongside the integration as it is not possible to have two open connections to the ABB-07.

While the app has the connection open to the ABB-07, the integration will not be able to connect to the ABB-07 and the reading(s) will be skipped. After disconnecting the app, the integration will be able to connect again and continue with the readings.

Setting the keep_connected option to True gives the integration exclusive access to the ABB-07 and no readings will be missed. Default (at the moment not configurable) every 1 minute the integration will try a reading and update the Entities in Home Assistant.
