I have this exact thing set up…
Here are instructions for the tile.
But you have to instruct it to refresh or it waits for you to manually push the refresh button. This is what I went with for that.
My set up for the reminder was when the outside temp was equal to the inside to remind me to shut them.
I also use this tile for outdoor lux ratings of 1000 or lower to turn on some lights inside the house.
