thermostat setup fail to load
I have a tado extension kit, and tado thermostat and a tado bridge.
The bridge is not connected to a router as I do not have internet onsite yet
I'm trying to configure the extension kit using the thermostat. The extension kit links with bridge successfully, the thermostat links with bridge successfully, but I cannot get into the setup menu on the thermostat to configure the extension kit to control the hot water. I tried this multiple times at distances between 2 to 5 meters. Every time when I try to get into the setup menu on thermostat it tries for a few minutes then displays fail on the thermostat display.
Does the bridge need to be connected to a router with internet for the setup menu to work?
