Comment on Security considerations of WiFi vs Zigbee for self-hosted IoT
Scrath@feddit.de 7 months agoThat’s a good point. Another one I have is sort of failure tolerance. I used to have a really unreliable router which would often crash and could only be reset using a full power reset. While it was in this state, wifi obviously stopped working but my zigbee devices where still available. I used to have a zigbee button linked to a smart plug for toggling my router off and on again.
This shouldn’t be a concern for most people obviously but I wanted to share my experience.
Another point I want to mention is that zigbee works at 2.4Ghz just like basic wifi so they can still interfere with each other.
Zwave on the other hand uses another frequency (I think it was around 860MHz) but is more expensive.

Do you think I’ll be able to use 915Mhz (I’m in the US) for ZigBee devices using the Sonoff controller and IKEA devices/custom devices?

Isn’t Zigbee always on 2.4GHz regardless of country? Trying to shift the frequency to 915MHz for all devices sounds like a lot of work with questionable benefit

Won’t it interfere with 2.4Ghz WiFi?

Well, theoretically yes but it doesn’t continuously send data and both WiFi and Zigbee also allow for operation on various channels. Does your neighbors WiFi interfere with yours?
Also, most WiFi devices now support 5GHz WiFi anyway so it’s even less of an issue anymore. The bigger problem would probably be WiFi interfering with ZigBee. But again, that can be resolved by changing the channels.
