    Run cat 6a, 48v is a good choice and you can use a simple dc to dc at the esp32 end. Can do the same for the sensor. Throw it all in a plastic workbox.

    from a cost and complexity the esp32 with poe is pretty cheap and you can probably tap into spare1 and 2 to run a dc to dc for the mm wave sensor.

    devices need to communicate with each other not just via the hub or worse several layers like your seeing. Throwing in poling makes it even worse.

    Your fixated on wifi throughput. That’s what I originally said, it’s a protocol issue typical of wifi devices. Not that you can’t get wifi to work well rather that IoT over wifi tend to be implemented badly.

    Latency is that wifi devices don’t typically talk to each other and have to go out the the cloud and back again, that’s everything from the fairly minor network latency to processing to various polling etc times all put together. It’s not the medium rather the protocol thats running over it.

    Z-wave is a lot slower but the latency between pressing a button and the light turning on far lower than your random wifi with a phone app and cloud junk. This is a function of the protocol used not the medium it’s working over.

    Latency is often an issue and why wifi tends to be a poor choice, devices need to communicate with each other not just via the hub or worse several layers like your seeing. Throwing in poling makes it even worse.

    Z-wave works well here you setup the association in your hub but the devices talk amongst themselves from then on.

    Not at least by the terms used.

    A modem converts say cable/dsl/fiber to ethernet.

    A router plugs into that and does NAT to hide your internal network from the world. Technically it’s a firewall but typically misused term is router in home networking.

    A switch plugs into that.

    Wireless AP’s plug into that along with any wired devices.

    Your ISP will often give you one box thats all of these things in one.

    The modem in the basement connected to a router with one more more AP’s around the house. I have 4700 sqf on 3 levels it’s 3 AP’s to get excellent coverage.


  • X-10 and the problem is it’s one way no confirmation or query of state. Lots of issues with this protocol signaling over powerline is not that easy it’s a pretty dirty place with all sorts of noise.

    Use a better mesh. Z-wave 900mhz is pretty clear, casetta 400mhz as well it’s just zigbee and thread that picked 2.4ghz mostly as it means same radio worldwide while it’s slightly different frequencies so a AU zwave can not talk to US one.
