FSESC 6.7 Pro v2 no battery stats on remote

Hi there,

My setup is now running nicely so far. The only think I am missing are some battery stats on the remote. It is always shown as 0%. If I do the setup input all the way through, it is shown. But after, let’s say 10min, it is all back to 0.

Any ideas what the cause might be?

Thanks,
P
