This is new out of the box. When trying to add doorbell it says hub needs update. I update on the App to 1.3.6 it says it has worked, but it hasn't, when I press the check update button it says needs

The Tapo App applied firmware 1.3.5 Build 20240726 to my Tapo H200. Why are both this Build and Build 1.3.4 not present in the overview of firmware versions on the Tapo website? Build 1.3.6 is present

Can i use two hubs to improve the distance. I have now one hub h200 in the livingroom For the garden is the signal to weak. Maybe i can to improve this to bought one h200 for the garden. Gr Toine
