  • I always keep Home Assistant as up to date as possible. Home Assistant keeps improving a lot. Month to month each update goes fairly seamlessly if HA is kept up to date, but the further it falls behind the harder it is to catch back up. Recent optimisation improvements have also made the update process faster.

    If you can make the time it’s worth the effort. Even if you have to “start over” somewhat there is probably a lot you have learned since that you can use to improve your setup.




  • Is it common for apartments to have shared extractor ducts? I’ve never heard of a setup like this before, and it sounds like both a pain in the arse and a potential safety issue.

    Controlling the kitchen fan is probably the easier bit. Depending on the design of the hood, you might be able to control it with a smart outlet or relay. Turn the hood’s switch to always on and control it with the relay. The difficult bit would be sensing when to turn it on.

    Cooking will often produce VOCs, and VOC sensors are easy to obtain, but they are also have other sources that are likely in your own apartment. Maybe try using temperature and humidity sensors int the duct to activate the fan when there is elevated temperature and humidity inside the duct?




  • In terms of privacy in public, the Vision Pro isn’t much different from Google Glass. Both have video recording capabilities, and both displayed some form of indication when recording.

    The only real difference is that the Vision Pro is easier to spot in public due to the bulkier design.

    It will be interesting to see if there will be similar “Glasshole” reaction to the Vision Pro once they are seen in public enough.



  • There are some Zigbee dimming relays/modules which should work with your Zigbee stack of choice. I haven’t used them myself as I use Zigbee dimmer switches instead, but I’ve seen others recommend them. There’s a few different brands depending on your country.

    I can also second the recommendation for the Shelly Dimmer 2. Works out of the box with the HA Shelly integration, and can also be flashed with ESPHome or Tasmota if you really want. It can also be used in detached mode to work with smart lights I believe too. My home is mostly Zigbee but I have a few Shelly devices and they have all been solid.


  • I also have an oil boiler, and a tank in the garden. The tank was fitting with an Apollo Ultrasonic oil level sensor, which sends a signal to base station with a very basic LCD display in the house via 433Mhz radio.

    I use an RTL-SDR USB radio dongle, a cheap 433MHz antenna and the rtl_433 software to monitor the signals from the ultrasonic sensor, which transits roughly once an hour. The level measurement transmitted is a fairly accurate centimetre value (I compared it with manual measurements with a dip stick for a few months).

    The base station only showed a vague level indication with 10 bars, but now I have more a more precise smart display of the tank level, without any extra modification to the tank system.









  • Personally I prefer using smart switches, or smart relay modules in between the switch and bulb. However that’s maybe not best for you if you are already invested in smart bulbs.

    The “neatest” options would be to fit a switch cover over the switch, or remove the switch and replace with a blanking plate. A smart button can be fitted onto the cover or plate to provide the functionality of a switch, there are devices with multiple buttons and even rotary knobs.

    Depending on the style of light switch used in your country there may be commercially made switch covers available if you can’t 3D print them. There are also several 3D printing services online that can be fairly affordable, I’ve had decent service from Treatstock.
