Tado Valve in downstairs WC losing internet connection
For a few weeks my Tado Valve in the downstairs worked perfect however, the last weeks its a different story. Its constantly losing its connection to the internet, it's off for minutes or hours, there is no notification that the batteries need to be changed (this has been the case for two others, new batteries required). The modem and bridge is on the same ground level and is maybe 15 meters away. Valves on the first floor which are further away have no issues.
I have added some screen shots to show what I mean.
All 6 other valves have no issues, just this one.
