Connect ESP32 to xiaomi Mijia-LYWSD03MMC without using HA
I want to do a little IOT project where I establish a MQQT-Broker on my Raspberry Pi and send it readings from my measurement devices (xiaomi Mijia-LYWSD03MMC). The plan is for these devices to connect to my ESP32, allowing me to transfer data to the broker on the Pi. I've successfully connected my ESP32 to my Wi-Fi and to my broker, but I'm experiencing significant difficulties in connecting it to my two measurement devices. I have essentially followed the instructions provided in this GitHub repository (https://github.com/atc1441/ATC_MiThermometer) as best as I could. I also checked some other repos but they didn't really help me as they were too big/complex...

Cheap WiFi temperature and humidity sensor
If you get off WiFi and on Bluetooth: https://github.com/atc1441/ATC_MiThermometer They last a year with a single CR2032 which is hard to do with WiFi.

Zero W and Enviro for boat monitoring project
I then copied this Python script to the Raspberry Pi 4 and was able to read the temperature and humidity! (https://github.com/atc1441/ATC_MiThermometer/tree/master/contrib/python)
- Any recs for the cheapest indoor smart thermometer that will work with homebridge?

How do you all monitor ambient temps for your drives? Cooking drives is no fun... I think I found a decent solution with these $12 Govee bluetooth thermometers and Home Assistant.
I’m using 16pcs Xiaomi Thermometer LYWSD03MMC BLE thermometer around the house with custom ROM from here https://github.com/atc1441/ATC_MiThermometer

IT Room Temp Monitor
I use the Xiaomi (pronounced Show Me) Mi Temperature and Humidity monitors (version 2) and flash the firmware with a 'open source' version (here or the older one here). I've found battery life good (8 months + with the newer software on one sensor) and bar from one corrupt display (right next to an outdoor electricity feed - well the box is handy and dry) then they have just run and run and run.

feels like winter today....not touching the heating tho
The thermometers in screenshot are Xiaomi Thermometer LYWSD03MMC with ATC custom firmware. Their bluetooth broadcast data collected by some cheap chinese ESP32 board and ESPHome addon in Home Assistant.

Reminder to check your local Micro Center’s website daily. Not only did they have stock, but they’re $15 off MSRP
You can replace their firmware with one which is more open and broadcasts the values without needing to connect to the device: https://github.com/atc1441/ATC_MiThermometer

ESPHome
I use ESPHome to enhance existing appliances (add smart functionality to an existing aircon for example) so generally the ESP board ends up within the appliance itself with nothing visible on the outside.
For things that need to be stand-alone I'd first check if there's an existing off-the-shelf option first which generally would be more cost-effective to buy and look better than anything I could make myself.
For temp sensors specifically I generally just go with whatever off-the-shelf stuff is supported by this firmware: https://github.com/pvvx/ATC_MiThermometer

Hoe warm is het bij jullie binnen in huis?
Home Assistant, with a bunch of Xiaomi BLE LYWSD03MMC sensors, running custom firmware: https://github.com/pvvx/ATC_MiThermometer

Which bluetooth adapter has been working well for you?
I have a handful of Xiaomi LYWSD03MMC thermometers running pvxx's firmware, and a SCD4x CO2 Sensor.

Xiaomi temp/humidity sensor
Personally, I flashed them with this firmware so I could customize the broadcast interval and use them with Home Assistant without needing a proprietary hub.

Hey, does anyone have a recommendation for a temperature sensor that works well with smartlife and homebridge? For a small price on aliexpress, thank you
If BLE is an option for you, consider a Xiaomi Mijia Hygrometer flashed (wirelessly via Chrome) with this firmware: https://github.com/pvvx/ATC_MiThermometer

Suggested HomeKit temp sensors?
Xaomi Mija Hygrometers, wirelessly flashed with this firmware, and Home Assistant to expose them in HomeKit. Local LCD display, roughly 2yr battery life, and available from $3-5.
- Is there a battery powered low power consumption device (BLE?) that has 1 gpio pin to monitor switch state (open/closed)?

Ask HN: What's on Your Home Server?
I've been using a Raspberry Pi as a home server, and it's been holding up amazingly well, given everything I've thrown at it:
- The excellent Home Assistant, for unifying across Homekit and Google Home and tracking historical temperatures and a couple of automations. The RPi has Bluetooth built in, so I can capture the data from a few Bluetooth thermometer/hygrometers running custom firmware (https://github.com/pvvx/ATC_MiThermometer) without a 802.15.4 bridge or similar.
- An AirPlay to Google Cast bridge, mainly for listening to Overcast or the occasional YouTube video on Google speakers
- A SMB server, for file storage and potential Time Machine backups (but I don't currently have enough storage, and locally attached SSDs are just hard to beat in terms of performance)
- A DLNA server, for watching photos and videos on my TV
- Tailscale, for the occasional use of my home connection as a VPN when traveling (really glad to be having symmetric fiber for this!)
- Caddy, as a frontend for everything web facing, to benefit from its excellent Let's Encrypt integration for automatic certificate requests and renewals
Most of this is running in Docker containers and configured via Ansible, so that if the micrSD card burns out, I can just flash a new one with an empty image and recover from there.
