InfluxDB write issue #328
Description
BatMON starts correctly and connects to both MQTT and InfluxDB add-ons in Home Assistant (connection parameters verified).
However, during startup it prints a warning:
17:57:21 WARNING [main] Failed to load influxdb sink: No module named 'mqtt_util'
After this, MQTT messages are still published as expected, but no data is written into InfluxDB.
Even when I create a new database manually, BatMON does not create measurements (previously it created measurements like battery1, etc.).
It seems the InfluxDB sink is not initialized at all after the warning.
Steps to reproduce
1. Run BatMON add-on with valid InfluxDB v1 connection parameters
2. Observe logs during startup
3. Verify that no new measurements appear in the database
Expected behavior
InfluxDB sink should load without errors and create measurement entries (e.g., battery1) as it did before.
Environment
• Home Assistant OS 16.2 (Raspberry Pi 5)
• Add-on: InfluxDB 5.0.2
• BatMON version: latest
• InfluxDB configured for v1 compatibility (database + username/password)
• MQTT working fine
