Tank levels

[rickardkk]

Would it be possible to have tank level readings? Not only would that help with resistive sensors but we can also use the Cerbo as a bridge to Homey for the Mopeka BT ultra sonic sensors.

I don't have a tank myself. Would that be com.victronenergy.tank? Do you have more than one tank? I'm guessing here, but would each tank get its own unit id in the service list?

[rickardkk]

Great that you’re looking into this one. Yes, com.victronenergy.tank is correct and you are also right about multiple tanks (they get it’s own unit id).

Have a look at the new test version. I don't have a tank myself, so expect some problems ...

[rickardkk]

Great! But unfortunately it crashes on startup. Can I help buy sending logs?

[ricott]

What crashed? When you added a tank device? Did you get an error?

The device itself has a setting which shows last modbus error. You can also trigger a manual diagnostic report on the app settings.

Unfortunately the app never starts. It says “App unavailable” and “Crashed” in Homey. Tried to trigger a manual diagnostic report on the app settings but that doesn’t work.

Also the Advanced settings is missing.

Managed to complete a diagnostic rapport: ac21d4f1-34f7-4e81-a390-e3b10a758de4

I got the diag report, trying to understand it ... As usual, things work fine here :(

Do you have a lot of flows connected to your GX device, or is it possible to remove and re-add it?

[rickardkk]

No problem. I’ll try to remove and re-add.

Unfortunately the problem remains even when starting fresh. DR: a3a976d9-0406-465b-9068-27096dec984a

I reverted a change I did involving the old GX device. There is a new test version. The tank and temp sensors use the same new code though for reading the modbus registries. Interesting to see if that works ...

[rickardkk]

Great!

Now the GX is working again but I get “Couldn’t connect to host” when trying to add a tank or temp sensor. I’m not sure if that’s because of the setup with BT tank sensors but I can try a traditional within a couple of days when I get home (on holiday right now).

It validates using the Modbus Product ID property. If it can read that, I assume we have the correct device type. Check the Unit ID of the tank/temp sensor as usual and use that one. Same IP and port as for your GX device. com.victronenergy.tank and com.victronenergy.temperature

Lets continue once you are back home 👍

[rickardkk]

Thanks!! I’ll get back to you as soon as I’m home again

[rickardkk]

Hi again,

I’m back at the island and can happily report that my tanks and temperature readings are working properly. Great work and a much appreciated feature upgrade to the already great Victron integration with Homey👍🏻

[ricott]

Great! Thanks for testing!
