I have the same wireless switches and also did not like them in the dark. So I bought little glow in the dark circles from Amazon. I put one on the button I would need to press to light up the nearest light. They work gerat. By early morning they are not bright, but you can still see them. In the bedroom I did not want to turn on the overhead so put the circle on the shelf light button.
I did once have an issue with the panel showing 1/3 on a grey tank and the phone app showed full. Turned out it was full. Sent a note to Firefly Integrations and they sent me a new touch panel (upgraded software) and a device to flash the main unit. Everything is great now.
But they also sent me to a website to repair the wireless switches as the new unit had to be paired. It also has other trouble shooting tips and should have come with the Thor manuals. Take a look.
