## Questions & Answers

**Q: Can this unit control two different lights in a two gang switch whilst maintaining manual button control?**
A: I mean to control them both doing the same thing at the same time, I do not need them to operate independently

**Q: Im using it for a roller shutter it works fine but the schedule does not work**
A: don't know the answer I flashed mine with ESPHome and use home assistant to control the schedule

**Q: Can this unit control 2 motors from one module such as velux windows?**
A: I don’t believe so, as the unit switch you will attach has an up and down function so that’s the two controls. If it was a light then you can do two lights. Once connected the App let’s you choose motor or lights etc
