Homey's software is always being improved. As experimental update tester you will receive updates before they are released to everyone, but these updates come at a cost: they usually contain bugs or missing features.
We recommend to not enable experimental updates unless you are a developer or are aware of the risks.
If you'd ever like to stop receiving experimental updates, your Homey must be restored to factory settings. Doing so will delete all your devices, Flows, etc. Read more about disabling experimental updates.
If you'd still like to enable experimental updates, visit https://developer.athom.com/settings.
