Adventures in CheapML for IoT

I have probably bit off more than I can chew with this project.

What is hard (or time consuming) about this?​

  • Generating the testing/training data set. I ended up using a VLM to do the initial labelling, with manual overrides possible
  • As I'm trying to run this with limited resources on a (RPI 4 with 4GB RAM) that means starting the ML models from scratch.
  • Trying to leave something that is generalizable enough for other cameras in the house - or just give up and pay the $20/mo for Frigate/Scrypted Cloud.

New Things​

  • PyTorch -> ONNX -> TFLite -> Latest

With Scrypted / Thingino up and stable, the next goal is to replace my janky garage door sensor with a camera-based sensor. With some luck, I can extend this to every camera in the house cheaper and more accurately than Frigate, but let's not get ahead of ourselves.

  1. What I have:

    • Wyze Cam v3
    • Scrypted
    • Thingino
    • HomeKit
    • RPI 4 that isn't melting

  2. What I need:

    • A way to detect when the garage door is open or closed
    • A way to update MQTT with the state of the garage door
    • A way to update MQTT with the state of the car

So far: I've vibe coded up a script to use OVNIF Snapshot protocol to take a snapshot of the camera every 60 seconds.

Almost bricking a v3 Wyze Cam (and back again...)

  • Wyze integrates and resells IoT cameras and devices for low capital cost, and has been under investor pressure to generate more monthly recurring revenue (missing source)
  • In addition, your data goes to the Wyze Cloud Infra on AWS where mistakes have happened.
    • I'm not judging, but I am if you are walking around naked (or worse) in from of a wyze product.
  • I'm not opposed to regularly paying Wyze for continuing to identify and bring promising solutions to the US from Shenzhen, BUT
    • I'm already paying Apple and Google - do I really need to pay wyze?
  • Scrypted and Frigate started as open source Private IoT Camera management software - streaming on the local lan via ovnif
  • They both work with the Wyze API, but Wyze recently change their firmware to force

NAT AT THE ROUTER FOOL (didn't work... why?)​
