Hi all,
I’m looking for a solution to detect dears using PIR in my yard. I wish to use zigbee as much as possible but so far, I dont find zigbee extenders capable to reach about 40 meters (120 feet). There is an ac outlet at the end of my yard so I searched a zigbee extender that could use the AC wiring as communication. But I found none.
I also have to say that Home Assistant is on a private (no internet) network if it matters.
Also, I’m thinking that I might need at least 4 sensors to cover the area I want. Cheap solution would be greatly appreciated.
Thats a challenge, no internet, but maybe you can go diy esp home sensors, if you had internet id say setup a sensor and have llm vision determine if it is truly deers as generally anything would set off a pir but ai (free gemini api) is more than capable of determining if it is indeed deer, and not another animal or object.
Hi,
I think that home assistant is pretty good designed for off grid usage but you need internet to download some local only integrations 
I don’t know any cheap capable motion sensor to do what you wish.
@zodyking do you mean a camera setup including llm vision?
The Frigate addon and integration in combination with camera’s is a powerfull local tool to use in this scenario.
Yeah i run llm vision integration on my security cameras, tells me what it sees etc. but i dont use frigate but i heard things about it and google coral
Thanks guys.
Yes I might setup and esp32. But since I have a spare pair of TP-LINK wifi extender, I could try something along that route. One connected to my private network router, and the other one at the end of my yard. I was hoping a simpler way. We’ll see!
Thanks
Need better detail on what you want to cover
300 sqft space 200’ from home with AC in SW corner
OR
40sqft space 200’ from home with AC in center
I use Ubiquiti nano bridge APs to extend network to far corner of my front yard. Here I placed network switch for camera and RasPi running zwavejs for a few sensors
A single ESP can run multiple PIRs or other sensors, definitely add ten and light. If center positioning is OK you can get a NEMA box and mount sensors on/in that. You likely have some play on wire length so mounting ESP in central spot and running low voltage cable to mount location of sensors is also an option
I placed my ecolink zwave motions outside and they worked out. They aren’t outdoor rated but they are $20 usd and battery powered
Have you considered LoRa
One option, if you’re willing to look at Z-Wave, might be using Z-Wave LR devices – these are Long Range, rated for communication at 1+ miles. Requires Z-Wave LR type of hub/controller, but doesn’t use repeaters – just a star network from the central point.
as a matter of fact, I was just thinking of that. Since I already have a “Zooz 800 Series Z-Wave long range S2 USB Stick ZST39 LR”. I see that the Zooz ZSE70 they say it is good up to 1300 feet. I suppose this is in the best scenario. I guess I would have to put the USB stick outside the house to reach that far. Wondering if anyone had experience with that if it is really good that far?
@tmjpugh the coverage isn’t that important as if I can reach the end of my yard, I can put several sensors as I need them. And if I can only get one sensor to work, it’ll be fine too.
But that zooz is really appealing if it really does the job.
