Same for adding the gx.

In the diag report it looks like you have a GX device connected?
DEBUG Polling 5 registries for 192.168.178.2:502:20 device type Temperature
DEBUG Polling 27 registries for 192.168.178.2:502:227 device type GX
DEBUG Polling 7 registries for 192.168.178.2:502:40 device type EvCharger
I see a number of these errors coming from a few different Homeys. It comes from trying to add a new device.
Examples:
RangeError: The value of "value" is out of range. It must be >= 0 and <= 255. Received 276
The value of "value" is out of range. It must be >= 0 and <= 255. Received 277
In your case @Dirk_vdM the error is
Reason: The value of "value" is out of range. It must be >= 0 and <= 255. received 512
Are these unitIds you are trying to use? I guess I need to add validation for them since they canât be larger than 255.
Yes, my GX has id 276 en my battery has ID 512,
I think you are confusing unitId and device instance id (not my invention).
Please have a look at this table from Victron, or use the recommended way to lookup your unitId.
To see a list of available devices, and their Address, go to Settings â Services â Modbus/TCP â Available services
Thanks, fixed. Didnât know those IDâs are different.
We both learned something, I added validation for the unitIds

Hello,
I tried connecting the charging station to Homey Pro. I filled in the IP, port 502, and com.victronenergy.evcharger, but it doesnât connect. Victron GX worked.
Can you help me?
Thanks
Hello,
Using homey and cerbo gx mk2 in my motorhome.
Is it not possible to connect the cerbo to the homey with only a smart shunt connected?
There are evchargers connected, so it should work. Have you looked up the correct unitId of the evcharger and what is there error you rae getting?
Install the test version and use the battery device type.
The com.victronenergy.evcharger is correct. I donât have any errors reported in Modus TCP. The modus TCP is actived. The Victron GX itâs working, only EV charger cannot connect.
Using the built in battery capability. Switch the tab at the bottom
Exactly, Thank you! 
Maybe a stupid question. But anyway.
I use the Cerbo GX in my motorhome. Using a MIFI and the Victron VRM portal I can read all the GX Values (temp, soc, MPPT, DCDC and the relays) in the app/internet
I presumed that adding the VRM as a device these values would become accessible in my homey at home.
This is not possible. Or am I missing something?
Hi,
When adding VRM you only get consumption forecast and PV solar forecast for today and tomorrow.

@Richard_B I was trying the test version of the app but i canât get the solar chargers to work, everything else (battery, multiplus, etc.) is working great. Is there a trick or a setting that i donât k know about maybeđ i think everything is ok on my part.
Just Feeding back on my setup
Solar charger - I canât install as the id is 279 and a limit 1-255 has been set in the device addition
Tank level isnât working, itâs reporting that the tank sender is 50% when itâs actually empty 0%(intentionally)
Still unable to add my Cerbo GX as I only have a DC system and therefore no VE.Bus
Hope thatâs all useful
Latest test release, v1.3.9, isnât stable. It updates values once after restart of application and then it stops. Same goes for the battery device, it updates once and then it stops.
Double check the update interval and its set for 10 seconds, tried restarting the app without any different result
Sent diagnostic report aswell.
Rebooted the GX device as well, didnt change the behavior.
Have sent diagnostics

There is some problem here. Since I dont have a solar charger I cant test this. But weâll get it working. Maybe send a diagnostics report.
Check a few posts above, use unitid and not device id.
Dont have a tank so cant test, but havenât heard of any problems before.
This is a bit strange and I would appreciate if more people comment if this is what they experience.

Im away skiing and back Monday, so unfortunately not much will happen until then.
Thanks @Richard_B
Have used the correct unit ids now.
Feedback is
The solarcharger isnât reporting back at all.
Regards to the tank being wrong Iâve noticed that actually itâs tracking the temperature so it was 13.2% full when temp was 1.3c now itâs at 14% and the temp has increased to 1.4c. They both share the same unitid - stable live version works as expected.
Smartshunt appears to be updating ok on the whole.
My thanks to you, Iâm grateful that youâre able to do the dev work and provide this functionality.
