Automation

E-VLXES32 can be integrate in HomeAssistant automation. The following pictures show a simple example: at 8.00 am the VELUX skylight is opened and after a delay of 5 minutes is closed.

Note:

It's possible to operate multiple VELUX skylight windows with HomeAssistant. However it's recommended to add short delay of few millisecond before to control other skylight windows. We noticed sometime interference between VELUX remote and VELUX receiver when multiple remotes are activated at the same time. This is easily resolved with a short delay as show in the following automation.
