Hello,
I am using a Marstek Venus E 3.0.
Firmware: V138
Local API enabled
UDP port: 30000
Battery IP: 192.168.1.101
Homey Pro 2023
Marstek Battery Connector v0.9.1
The battery is automatically discovered by Homey.
Model: VenusE 3.0 v138
Firmware: 138
IP address: 192.168.1.101
UDP port: 30000
The device is successfully added to Homey, but it remains “Inactive”.
No values are received.
Battery SOC
Battery power
Charged energy
Discharged energy
In the Marstek app the battery works correctly.
The Local API is enabled.
The battery charges normally in Manual mode.
No errors are reported.
Homey correctly detects the battery IP address, model and firmware, but no battery data is received and the device remains inactive.
Has anyone successfully used a Venus E 3.0 with firmware V138 and the Marstek Battery Connector app?
Do I need any additional configuration?
Thank you.
