homecom-alt
Async Python wrapper for controlling Bosch Thermotechnology devices managed by the HomeCom Easy app. Communicates with the pointt-api.bosch-thermotechnology.com REST API using OAuth2 (SingleKey ID) authentication.

Matter-commissioned ACs (Bacon)
Bosch Climate ACs commissioned over Matter in the HomeCom Easy app (serials
like 86DM-580-…) are not pointt gateways, so they never appear in
HomeComAlt.async_get_devices(). They are managed by Bosch's bacon backend and
controlled through an AWS-IoT-style device shadow over MQTT 5 (WebSocket),
which requires the extra paho-mqtt dependency (installed automatically).
- Discover them with
async_get_bacon_devices(session, token, region)— returns the same{"deviceId", "deviceType": "bacon_rac"}shape as the REST discovery. - Open one shared
BaconMqttClientper account (async_connect(token, sub)), then wrap each serial in aHomeComBaconRacforasync_update()and theasync_set_power/async_set_mode/async_set_temperature/async_set_fan/async_set_swingcontrols. - The region defaults to
euc1(eu-central-1);use1also exists.
Authentication
ConnectionOptions supports two auth flows:
- OAuth2 code flow (recommended): provide
usernameandcodeobtained from the SingleKey ID authorization endpoint, and setauth_provider=Truewhen callingHomeComAlt.create(). - Token reuse: provide an existing
tokenand optionallyrefresh_tokento skip the login step.
The brand field defaults to "bosch" — use "buderus" for Buderus-branded devices.
Usage
See example.py for a full working example.
Error handling
| Exception | Raised when |
|---|---|
AuthFailedError |
OAuth2 authentication fails |
ApiError |
API returns an error response |
NotRespondingError |
Device does not respond (retried up to 5 times with exponential backoff) |
InvalidSensorDataError |
Sensor data cannot be parsed |
All exceptions inherit from BhcError.
