Introduction
Two months ago I’ve replaced my 15-year-old washing machine with a new one and I also bought a dryer. Both devices are from Bosch (Serie) 8 with WiFi and Home Connect. Today I may present integration of those two household appliances with Loxone. In my solution I use ioBroker do retrieve data from Bosch Home Connect cloud and to publish it to MQTT broker from where the MQTT Gateway Plugin sends it to Miniserver UPD port. Everything is done within one LoxBerry system running on RPi4 mounted in a DIN rack. Integration provides insight into device status, current program, program progress and remaining time. It provides also push notifications at the end of washing / drying job.
Those are the appliances I’m using: Bosch WAVH8K90PL washing machine at the bottom and Bosch WTX87KH0PL dryer at the top. Please mind the product codes are country specific. I chose those specific models because of the features that were important to me: the i-Dos system in the washing machine and the AutoClean system in the dryer. Both devices have the same load capacity of 9 kg.
Prerequisites
You need to have:
- Loxberry system with MQTT Gateway and Docker plugins
- ioBroker run as docker container, with MQTT client and Home Connect adapters installed
- Both washer and dryer successfully connected to Home Connect cloud
- Home Connect adapter paired with your Home Connect cloud account. This is not exactly easy but its well described in adapter manual:

Integration with Home Connect might be done in different way (probably directly from ioBroker to Miniserver websocket API). I personally prefer to integrate as much external systems as possible over MQTT and that's just my way. |
The Data
This is how the object tree should look like in ioBoker after you successfully connect the adapter the Home Connect cloud:

The Diagram
Heart of the integration – the diagram. In the next two pics additional details will be shown, but first I mention two tricks were required due to flaws in Home Connect API.

Please note: most of status texts in image above are in Polish (that my native language and the language of my Loxone app interface).
I believe you will figure out their meaning by yourself but for your convenience I attach a some basic translations

Details of the right part of the diagram related to the dryer. Many elements are similar obviously, but not everything is:
The App
This is what it looks like in the Loxone app. On this screen washing is in progress and the dryer is not in use. The estimated remaining time of washing or drying is an information that might be useful in everyday life logistics:
