5e? 6a minimum not much price difference. We all already running multigig to AP’s. Really go with a recessed and keystones with smurf tube back to your wiring closet.

Where are the TV’s and displays. They need some Cat6a as well. Data and don’t forget hdmi over twisted pair.

22/2 for Door/Window sensors why not /4 in case you need a second contact run or something powered. I did conduit to the window and doors it’s an easy place to access already used one to get an extra camera run. Takes care of the power shades as well.

zwave or wifi and will work without a c wire.

All of the google nest line.

There are countless smart thermostats that can do this with getting into hacking dry contact relays in parallel.

Yes HASS natively supports roku and will let you change inputs (they are apps in its terms). So you can make automations based upon an app starting switch apps etc.

Any roku smart tv can do this via API, home assistant already has a binding.

Not sure you will like how it works as the Hulu app would restart.

2600 bucks for

3kwh of battery that’s about 700 bucks

3kw inverter/charger 1k

200w of solar 100bucks

You need 2 of them to get split phase 240 needed for a US home.

5k for 6kwh setup that still does not have a ATS etc to work well

I would and did get a pair of victron inverters for about the same money you can get 10kwh of batteries and expand from there. These work with a generator and integrate well with home automation (they talk MQTT so easy to deal with)

Proper isolation is what stops them.

HA/IoT should be on it’s own isolated SSID (wifi name) and Vlan with only the hub connecting to it. This becomes the one thing you have to trust but between open source and reputable vendors you have plenty of choices here. It’s also the device that provides a modicum of security since you can keep it up to date.

Now from a practical standpoint if it’s just a mmwave presence could wire those all back to a central location and avoid putting a micro in every room.

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.

Only if they have a device to device communication channel that most wifi devices lack. Like I said the problem is not the medium but the protocol design. Wifi’s orders of magnitude faster throughput does not fix a bad protocol.

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.

First off the squash down the rates significantly.

Lets use netflix for example they will ship ISP with enough traffic open connect appliances. Each one caps out at 2x100g connections so about 200x as fast as your home plex server. They can deploy many of these as any given ISP preferably closer to end users where there is more free bandwidth.

On the smaller end they aggressively peer with pretty much anybody even down to 10g links. It’s free ish bandwidth for them and the ISP so a win win.
