Ablemail ABB-07

[RioRob]

I recently installed an Ablemail AMT 12-2 battery maintainer and associated ABB bluetooth interface.

The AMT seeems to work OK but I can't get a reliable connection to the ABB.
It connects but is very slow to respond and drops the connection after a short time which means I can't change the settings including the low power enable.

The phone is Android 14 & I'm wondering if anyone else has this problem.

I tend to connect a 12v supply to the SW2 terminal which keeps the AMT12 powered up. In fact the cable is installed on to one of the Victron relays, so I can switch it on/off. If left on the AMT12 is permanently charging, so will use more of the leisure battery than when it is on one of the standard settings.
