Hi @Peter_Hendrix,
Hopefully this will solve your issues.
Please note that the support for this wireless dimmer is only available in the v2.0.3 version of the ROBB smarrt app; which does require the experimental Homey v5 release. The Ikea app is already updated for Homey v5 (test version), but not all apps (like the Aqara).
Before updating to Homey v5, please check if your apps are available for this experimental release.
