Compatibility - BMV-712 #24

Closed davewatson91 closed 10 months ago

davewatson91 commented 10 months ago

Love your work - this is a great solution for those not wanting to physically wire into their units (I have a camper which I would rather not keep an ESP powered on).

I'm trying to get it going, but not sure on compatibility. I have a BMV-712, which shows up in the app as the screenshots below. It's not on the list explicitly, but (likely wrongly) assumed that given it's compatible with the rest of the Victron BLE gear, that it would be.

Hi, The BMV-712 is supported. Just use the Instant readout details / Encryption data provided at the bottom of the page.

Perfect thanks! @Fabian-Schmidt.

Is there any basic troubleshooting steps I can take as to why I'm getting nothing output when setup like that?

Fabian-Schmidt commented 10 months ago

Use the ESP Home logger and check the output. See https://esphome.io/components/logger for reference. Adjust Log Level to get more details.

My recommendation is to use the hardware logging. So connected via USB and logging via USB/Serial and via Wifi / Ethernet as this can have significant impact on the outcome.

Thanks - managed to find some issues - all working now!

Fabian-Schmidt commented 10 months ago

Any lessons learned or things which I can add to the readme to help other avoid this issue?

No, the docs were quite good - it was my own stupidity that caused me dramas (interference causing a crazy low range (<1m) out of the BLE.
