Dimmer does not report back percentage

I have a few dimmers around the flat that I control with sharptools. Controlling them works well but for some of them, sharptools does not report back the dimming percentage the device is set to. Instead, I get a triangle with an exclamation mark in front of the percentage.

Is there anything that can be done about this to make it work?

If this is on Homey, try restarting the SharpTools ‘app’ on your Homey as a first-step in troubleshooting.
