Multiple GX units, Temp inputs

Does anyone know if the Temp inputs from a second unit (venus, cerbo etc...) will show on the CCGX and vrm? Like the multiple tank inputs do.

A) For in chapter 1.4 - Multiple GX Devices for increasing number of tank inputs

(or to be put in a separate chapter)


Introduction

The number of tank inputs of a GX Device, such as the Cerbo GX and the Venus GX can be expanded by connecting multiple GX devices together in a VE.Can network.


Make sure to designate one GX device to be the “main” one; and the other(s) to be the “secondary” one(s). There is no practical limit on how many can be used - most likely the number of source addresses on a VE.Can network is the limit, which is 252 addresses. A Cerbo GX, with 4 tank inputs, will use up 5 addresses: one for itself, and one for each tank input.

Hi @Alan

I just tested: no they don't show up.

ps for multiple tanks it is now adviced to use the GX tank 140:

Thanks for testing it for me, I'm more looking to add temp sensors to a ccgx.

Looks like the only option is to go down the IMT solar modbus RTU route. Is it possible to rename the sensors or are they stuck with the discovered name?


Is this really the only way to add temp inputs to the ccgx?

modbus tcp temp sensors would be great as they could be simply added to the network (either wireless or wired) and installed remotely from the gx device.
