I have new UT800 and RTL515 installed and, I believe, updated with latest versions. However, when I turn on Edge it shows the lights but does not show the battery amounts. When I click on the light it may, or may not, show the light setting information. I am pulling my hair out and I have a shaved head... Both devices are enabled and charged. I have removed devices and re-installed them. I just want this awesome tech to work!
Update - after I typed above the light network was formed and RTL started to flash. I clicked on the light and it showed the setting screen and then, almost immediately, the light network dropped and started forming "a new one". UGH!
