ᐅ Control of Multiple Roller Shutters

Or Shelly 2.5

No one knows them, but they are a very likeable small company. (No, not related or in-laws :-P)

Shelly uses Wi-Fi for communication, right? I wouldn’t voluntarily want to put my home automation components on such a crowded frequency band. Personally, I would much prefer a system operating in the less interference-prone 868.4 MHz band.

Preferably with EnOcean, since this protocol is considered to provide one of the most stable communications compared to Zigbee or Z-Wave. For example, there is the NodON Roller Shutter SIN-2-RS-01, which is compatible with many gateways. Add a wireless switch (flush-mounted or access point), and the system works— even battery-free, making it low maintenance.

Well, it is suitable for a bit of experimentation and trying things out. However, if you want to do more, you inevitably need to switch to something better.

@Strahleman: It depends – in a concrete house, you have little interference from neighbors, and one Wi-Fi access point per floor is cheaper than one EnOcean gateway per floor (which you need anyway). Or do you have a tip for a cheap EnOcean gateway?
Battery-free is not relevant for roller shutter control since power is available at the switch anyway. But for window sensors, that is an important factor.

I completely agree. If you want more than just changing the colors of the room lights, you should use a comprehensive solution from the start, and in my opinion, right now that means something wired. For small tasks like raising/lowering blinds or turning lights on/dimming/off, wireless is definitely sufficient. I wouldn’t want to handle complex sequences and automations with it.

Edit:
@BigFoot: If properly set up, one EnOcean gateway should be enough (e.g., Homee with EnOcean Cube), plus depending on the size of the living space and the number of floors, one, two, or more Eltek EnOcean repeaters. If you have some time, you can get a Raspberry Pi with an EnOcean extension (e.g., EnOcean Pi) for a fraction of the cost of the Homee. Of course, the roller shutter controls are powered by mains electricity anyway. However, I find the battery-less access point switches and the various sensors great. With my current Zigbee setup (luckily only one Osram switch), I have to change the battery every few months, which eventually gets annoying.

I don’t understand the argument – either the control system is stable and reliable (which can also be wireless), or it isn’t.

Whether I add automation via HomeAssistant, openHab, etc., doesn’t really matter.

Unless you mean that the only true automation can be done with KNX. But even then, KNX is usually just used for control nowadays, while automation is handled by tools like openHab because they are much more flexible.
