If you have a eufy scale, you can do this with no LLM needed - just set up an esp32 Bluetooth proxy, add it to home assistant, and then use the EufyLife integration someone already made. I did this recently with my scale to avoid having to sync it to my phone, go to the cloud, fetch data from the cloud, etc., and it's working fantastically. I have a little Home Assistant integration that pokes scale updates to a Python script running locally that provides a UI I like.
Huge fan of running it this way.
(Yesterday I ordered a more commercial, polished-looking esp32 Bluetooth proxy integrated into a smart plug - athome brand - but it's the same functionality, just in a nicer package than having a USB thing dangling from my outlet)
- toomuchtodo 9d agoIs there any documentation and a specific esp32 Bluetooth proxy you would recommend?
- dgacmu 9d agoesp32 bluetooth proxy: There's a standard esphome component that just turns any esp32 with appropriate h/w into a BTLE proxy: https://esphome.io/components/bluetooth_proxy/ https://esphome.io/components/bluetooth_proxy/ I'm just using a cheap ESP-WROOM-32 but the recommended way to do it is with an wired ethernet-based ESP32 so you don't have interference with the wifi and btle. For a scale this works well enough. I haven't yet received the athom smart plug so I can't recommend it yet. Should be here in a week or so. Once you've got the proxy you can just use the eufylife integration: https://www.home-assistant.io/integrations/eufylife_ble/ https://www.home-assistant.io/integrations/eufylife_ble/ To setup the esphome bluetooth proxy you install esphome, and then create a yaml file that you'll use to configure the board, like this: esphome: name: bluetooth-proxy esp32: board: esp32dev framework: type: esp-idf # Enable logging logger: # Enable Home Assistant API api: encryption: key: "YOUR_KEY_HERE" # Enable OTA updates ota: - platform: esphome # WiFi configuration (matching the settings from your other devices) wifi: ssid: "YOUR_WIFI_SSID" password: "YOUR_WIFI_PASSWORD" # Enable fallback hotspot (captive portal) in case wifi connection fails ap: ssid: "Bluetooth Proxy Fallback" password: "proxyfallback" captive_portal: # Enable ESP32 BLE Tracker esp32_ble_tracker: scan_parameters: active: true # Enable Bluetooth Proxy bluetooth_proxy: active: true Once that's done, plug in your board to your system and use esphome run bluetooth-proxy.yaml (you might have to find the device it's showing up as in tty.usbserial or whatever).
- toomuchtodo 9d agoThanks so much, I appreciate the time you put into this comment. It is highly relevant to a project I’m currently working on, and has saved me at least a day of time.
- dawnerd 9d agoI actually found this out by accident. I set up a BT proxy to capture my combustion thermometers and saw eufy show up as an option and was like wait what? Honestly surprised how open it is.
