Google nest show data


When you ask the nest hub “what’s the temperature outside” it says the temperature but also shows the temperature.

I want to do the same with a variable from homey. I don’t know how but I want it. Haha

For example I’ve a diy rain gauge. Measuring the rain per day. When I ask google it will say the measured rain (via routines and homey).
It would be nice to display the value very large on the screen.

I’m aware of the dashboard etc. That’s not what I’m looking for. Maybe there’s an option to write the value down to a site and cast it to the nesthub. I’m not familiair with building a site or hosting (don’t have an synology or something like that).

Does someone have an idea of suggestion?
