Can you tell me which kind of devices show no data?
If you can send me a screenshot, I will try to implement theses device types.
I tried to test a lot but because of the mass of plugins and device types I can’t cover everything from the start
The reload animation is only a blur over the icons to visually show that you can’t interact act the moment. It only lasts as long as your pimatic server needs to respond.
If you run pimatic for example on a raspberry pi 3 you shouldn’t be seeing very much of this.
