Integration with evcc#

evcc.io is software for intelligent electric vehicle charging. GbbOptimizer can communicate with it via MQTT to coordinate EV charging with home battery optimization.

Requirements#

A working evcc installation
Local MQTT broker (Mosquitto in Home Assistant or standalone)
Configured Mosquitto Bridge

Bridge Configuration#

In the Mosquitto configuration file (/share/mosquitto/GbbOptimizer.conf) add topic lines for evcc:

1
2
3
4
5
6


connection GbbOptimizer_<PlantId>
remote_username <PlantId>
remote_password <PlantToken>
address <mqtt-server-address>:8883
bridge_capath /etc/ssl/certs
topic # both 2 evcc/loadpoints/ <PlantId>/evcc/site/loadpoints/

MQTT Topics#

Data from evcc (evcc -> GbbOptimizer)#

Topic	Description
`{PlantId}/evcc/site/statistic/total/chargedKWh`	Total energy charged to EV (kWh)

Commands from GbbOptimizer (GbbOptimizer -> evcc)#

Topic	Payload	Description
`{PlantId}/evcc/loadpoints/{chargerId}/mode`	`off` or `now`	Enable/disable charging
`{PlantId}/evcc/loadpoints/{chargerId}/maxCurrent`	number (A)	Maximum charging current
`{PlantId}/evcc/loadpoints/{chargerId}/connected`	`true`/`false`	Charger connection status

Where {chargerId} is the charging point identifier in evcc.

Tuya

Integration with Tuya#

GbbOptimizer can control Tuya devices (e.g. smart sockets) via the Tuya Cloud API. This requires creating a developer project on the Tuya platform and obtaining API keys.

Obtaining Access ID and Access Secret#

1. Create a developer account#

2. Create a Cloud Project#

Go to Cloud -> Development
Click Create Cloud Project (top right corner)
Fill in the form:
- Project name — any name
- Industry — select the appropriate industry
- Development Method — Smart Home
- Data Center — select the one closest to your location
On the next screen click Authorize

3. Connect the mobile app#

Go to Devices -> Link App Account
Click Add App Account
A QR code will appear
In the Tuya/Smart Life mobile app: Me (bottom menu) -> scan icon (top right corner)
Scan the QR code

After connecting, a list of your devices will appear in the All Devices tab.

Supla

Mon, 01 Jan 0001 00:00:00 +0000

Integration with Supla#

GbbOptimizer can control Supla devices (e.g. relays, smart sockets) via Direct Links.

Configuration#

To connect a Supla device to GbbOptimizer, create a Direct Link in the Supla Cloud panel:

Log in to cloud.supla.org
Go to the device you want to control
Create a Direct Link with the appropriate permissions (on/off)
Copy the generated URL
Paste the URL in the GbbOptimizer configuration under IoT -> Supla

A detailed description of creating Direct Links can be found in the Supla documentation.
