Firmware version 3.0.0 update and not-athom-store-app

Hi

I have a couple of apps that are not from homey app store and those are not updated to homey version 3.0.0 compatible. Will these apps still work if I update the Homey to version 3.0.0? I’m a little conserned about the update. What is the worst thing that could happen?

I have a Aeotec app from the github for the Home Energymeter G5 to work and one nordpool app to get the electric prizes.

Apps will continue to work. Apps don’t show the energy like in 3.0 tho.
Most apps have a line with like “works with 1.5.3 and higher” .
So they will most likely still work.
