Hi,
VE.Bus Smart Dongle produce page states:
Secondly it can work as a Voltage- and Temperature-sense device for the inverter/charger. This works with all models, and is especially useful in combination with the MultiPlus-II, as it does not have on-board terminals for Voltage- and Temperature sense wiring
... on-line manual:
On MultiPlus-II models the dongle is, at present, the only way to add an “on-battery” sensing capability.
and:
Likewise, the dongle also monitors VE.Bus communication in order to discover if a Venus-device is supplying the Multi with battery voltage and temperature data. It takes around 4 minutes after power on, or reset, before the dongle decides whether or not to transmit the battery voltage and temperature.
Now, I have MultiPlus II (that is without battery temperature sense capability) and GCCX Venus device. From what I read, I expect that dongle would provide battery temperature data (since there is none present on the bus), but it seems that it does not! When I do dbus-spy there is no signs of battery temperature at all.
I am confused. It seems that VE.Bus Smart Dongle is practically useless (it just provides battery voltage and temperature over bluetooth) when there is GCCX Venus device is present on the bus... or am I wrong. My plan was that VE.Bus Smart Dongle would provide battery temperature to the system.
Thanks,
Matej
