--- Quote from: WaveyDipole on October 23, 2022, 12:16:49 pm ---That is interesting. I researched Zigbee and it would appear that it uses the same part of the 2.4GHz band as WiFi and is said to interfere with it unless carefully set up. On the other hand, reliability is an important consideration as well. As it happens, a friend of mine has some home automation and has been complaining about the WiFi "freezing". They even had a Virgin Media engineer out to investigate and they found nothing. I would have to investigate further, but this might have just provided me with one possible explanation. --- End quote --- It's possible that I'm just lucky, but I have lots of zigbee devices, some bluetooth, 2.4GHz WiFi and a microwave oven in my house and everything coexists harmoniously. I don't think all of the available WiFi channels overlap zigbee. Also zigbee is used for low traffic stuff like home automation, just a few bytes flying around. |

Don't worry too much though. Your government will find a way to do this for you. :popcorn: |

Zigbee is also a mesh network*, so if a lightbulb can't reach the hub, it can hopefully receive commands through another bulb or device. It's also only a few tens of kbit/s so not really a big deal if signal strength is weak as modulation scheme is minimal. *Does not apply for (most) battery powered devices which act as receivers only |

I actually find that many elderly people are more glued to their phones than young ones. (My theory is this: young people grew up with smartphones and understand that not every notification demands an immediate response. The elderly, in my observation, tend to treat every incoming call and text message with the utmost urgency, kinda like back in the landline days…) |
