Everspring Siren SE812 does not respond after inclusion and initial config. It responds instantly if battery removed and reinstalled then becomes silent again. Battery checked Ok. The unit was placed in close proximity of controller <1M while checking. The unit is configured in my VERA-1-UI4-as Siren and the device type as (urn:schemas-upnp-org:device:BinaryLight:1). I tried Heal / Repair without results. I have 3/4 Fibaro Relay and Dimmers as neighbor nodes. I emailed to customer service of Everspring in Taiwan with 2 reminders about 2weeks ago and yet to get any response. can someone amongst you help!
