Hi,
In reference to New HA powered house plans
I’m looking for reasonable selection of PoE sensors:
I don’t want DIY stuff, I don’t have time and skills to assembly them.
PoE because:
There’s a rich selection of Zigbee and Wifi sensors, but all battery powered.
Any hints?
Unfortunately I’ve never seen PoE versions of any of those sensor types. USB-C, yeah, but never PoE.
With that said, there are PoE to USB-C RJ-45 adapters usually costing between $20-$40 US. I use them with my Raspberry Pis and they work pretty well.
$20 for POE to USB alone is quite ridiculous markup to count on top of each sensor. It will be cheaper to connect 230V cables everywhere (I’m still at the design phase for the house) and just attach USB chargers everywhere.
I don’t disagree. 
I was answering your question and offering an alternative should you be dead set on going with PoE. 
Got it 
Any recommendation for USB charged sensors? Tuya and other popular brands don’t have them…
You can buy battery delete kits or just run wires to every device. The #1 thing you need to pay attention to is the voltage of the device. If you apply too much voltage you will cook the device. Here’s a picture of me powering a z-wave device that takes coin cell batteries with a power supply.
I am using reolink poe cameras as my security setup (don’t worry, I deny them internet access across the whole vlan). Their primary purpose is a feed to my BlueIris server. This gives me the opportunity to either use the motion sensor itself on the camera as a trigger in HA for motion lights, in addition, since blue iris has its own detection, I can use an either/or trigger for my automations which works very well. I could probably set up a sound trigger since some of the cameras have microphones.
I also use the poe to usb converters for my chromecast and Rpi’s. However, the Rpi’s were only in place for watching movies off the NAS years ago. Now the chromecast handles all the media duties with the app called localcast. I really need to repurpose them as some sort of sensor(s).
I too would like more poe sensor availability with HA, especially anything that is locally controlled since I despise cloud control. You never know when some product/api is going to be EOL, or if a company gets bought out and shut down. With some things, cloud is the best option,. However, I will always be of the “local control” mindset.
Anyone else have anything to contribute?
