@LeeC77 @candiesdoodle - glad to hear . Can you monitor updates coming in after 6 hours of run time. I haven’t had it up for that long without removal/adding where I’ve been testing so hopefully it logs back in again. I may have to play about with the login interval if not.
Although you can use devices offline (local mode), the binding has to send a login message every six hours to the api in order for the device to keep pushing out updates on the LAN. If you do want to entirely disable this, you can put supported devices into developer mode (untested but should work) and block the devices internet connection.
If you don’t want to put them into developer mode, you can still block the internet access and switches will function, however you wont receive updates for channels such as power,energy,current if you have the likes of a POWR2. You should however still get switch updates should it be changed from elsewhere.
