If anyone has one (or more) of these hanging around you don't want/need/love anymore, I'd be keen to take it off your hands!

Want to setup some dog tracking stuff so the house alarm isn't set off when the dofus dog is inside.

Thanks,

I asked a while ago as I could not find any in NZ at a reasonable price.

https://core-electronics.com.au/raspberry-pi-zero.html?src=raspberrypi (They have them at about 25 incl Shipping to NZ)

They come up on trademe once in a while but people want some horrible prices for them.

It seems that most of the sellers on trademe want rip off prices for anything arduino/raspberry pi related.

Thanks @LennonNZ, sadly that's the non-W version.
I want the Wireless version for Beacon tracking.
I think I've found them on Amazon though.

If you're desperate adafruit have them back in stock but the shipping is ridiculous ($25 usd), only worth if you are buying a few other things.

Edit: Should also add they have a limit of 1 because I wanted to split shipping with a few people.

I've got one in a drawer you'd be welcome to. Located in Hamilton. Feel free to drop me a message.

I managed to get one on TM about 6 odd months ago from phoenix-tech for $30 incl. shipping, but they don't seem to have anything right meow.

Amazon would probably be the safe bet, but 25USD incl. shipping isn't exactly cheap.

For BTLE Tracking also consider and ESP-32 based device. I've got one running in the middle of our house and it can track all of our Xiaomi Temp/Humidity sensors and our smart watches.

You have my attention.

Can you show me what device it is you bought, and what software it integrates with? I want something I can "just buy" that'll be able to join my wireless network and basically just needs power and an SD card or something to boot off. I'm using Home Assistant.

I have a happy bubbles already living in my carport and it "sees" the car when it pulls into the carport (there's beacon in the glovebox) and that works great for a number of automations. I want to put a beacon on the Dog's collar and be able to tell if he's in various rooms. I was going to use https://www.room-assistant.io/ which appears to be well setup for a Pi Zero W.

Cheers!

Couple of guides

I'm using esphome with direct HomeAssistant integration/discovery.

One issue I've got is the BTLE support breaks OTA updates. Need a simple way to enable/disable BTLE for OTA to to work.

Make sure you use an ESP32 device as it has Wifi and BTLE built in. Just need to find a suitable case.

So your link is dead, but I can see nicegear sell a SparkFun ESP32 thing. I like NiceGear, they're good people (person?)

https://nicegear.nz/product/sparkfun-esp32-thing

Would that work?

What do I need to program it? How do I set it up to access my Wifi network? Do I need a seperate programming board or something, or do you just plug it into your PC and program it that way?

Looks cute, but also makes me feel like a doofus. If it's Linux I know how to drive it, if not, errr what do I dooooooo :)

Thanks!

You can find devices on Trade Me as well

- https://www.trademe.co.nz/electronics-photography/other-electronics/electronic-components/other/listing-2693141432.htm?rsqid=6c03d49cf9354642a758e2f8ecaffd6e-001

You can program it using Arduino IDE or esphome on the command line, and it connects via a micro-usb connector.

Device doesn't run Linux, you treat it like an Arduino device. Took my 5-10 minutes to get it cabled up and have some demo / example BTLE discovery code running.

Yea I've never had a Arduino device either, but I guess I might as well learn.

Thanks everyone.

If you go for Arduindo and C isn't your thing then check this out. Can totally recommend it and it's free.

The Arduino IDE has a lot of example code to get you started, plus some great online examples are out there for your use-case.

Yea I bought the last two SparkFun ESP32 things on Nicegear's website last night.

Had a play with the ESPHome app etc, looks pretty easy to figure out and get working.
