Veralite baterie lost

Hello

My Veralite works great since 2 week and 2 days ago I lost SP812 baterie I have a ? and today the same thing for my HRT4-ZW.
Every day I change the SetPoint of my HRT4-ZW with success, if I change temp on the HRT4-ZW I have instant change on UI5.
Do you know this issue ?

Thank you for your help

I have the same thing on my SF812. ???

What is the range like between your Vera and the other devices? Also do you have any other intermediate non battery powered Zwave devices?

My SF812 is about 15 feet from Vera, in line of sight.

My SF812 is about 6 meters from Vera.
I have a ASR-ZW and AN158 but they are at 12 meters from Vera.
