I got a #fullframe #camera #d750 .. it's great but apparently full frame has less depth of field, surprisingly plus the lenses are more expensive... should I have got an aps-c instead .. the #nikon is big .. I'm attracted to #mediumformat but the development costs seem prohibitive... so I was looking for a way to do that digitally.. I figured full frame was better because the #sensor is larger. #photography

I wanted a flexible door sensor with a long battery run time that works with the hardware I already have. I settled on the Xiaomi Mijia MCCGQ02HL Window/Door Sensor 2 which I got used for 6€ per device. It can run on a single battery for over a year by broadcasting the data as a Bluetooth beacon. No change, no transmission, no energy consumption.

I use a #Raspberry Pi Zero (thx @b30) to capture the BLE beacons and send them to a MQTT server (mosquitto) to which my Home Assistant instance is subscribed to.

More details:
1. Get hold of a MCCGQ02HL sensor.
2. Add the sensor to the Mi Home app with your smartphone.
3. Extract the encryption keys. I used https://github.com/PiotrMachowski/Xiaomi-cloud-tokens-extractor (other options are listed here: https://custom-components.github.io/ble_monitor/faq#encryption-keys)
4. Write a python script to capture and process the BLE advertisements. I adapted the example script from the bleparser package (https://github.com/Ernst79/bleparser) and added home assistant discovery functionality. It's a mess, but if you want something to start off from: https://gist.github.com/lucahammer/24a60aadb16a53c200f2b9174b441fef. Add the MAC addresses to the sensors list and the BLE keys to the aeskeys dictionary ('MAC:ADDRESS':'KEY'). I don't know why it needs to be in bytes instead of strings. Add the MQTT server IP, port, user and password.
5. Put the script on a device with Bluetooth capabilities.
6. Install dependencies (aiobs, BleParser, mqtt).
7. Run the script. I have to run it as root. If you know how to fix that, let me know.
8. If your home assistant instance is already subscribed to your MQTT server, the devices should show up automatically.
9. ???

If your home assistant host supports Bluetooth and is within reach of the sensors, you can ignore all steps and use the BLE Monitor component (https://github.com/custom-components/ble_monitor) instead. #HomeAssistant #Xiaomi #Sensor #HomeAutomation #Python #MQTT

(I run a very similar setup with Xiaomi Mijia LYWSD03MMC temperature and hygrometer sensors. Those with a custom firmware though https://github.com/pvvx/ATC_MiThermometer)

I have installed the new 433Mhz antenna on my home temperature sensor SDR receiver. One guess as to when.

I haven't mentioned this in a while.. #Django Channels are friggin cool. I'm on my 4th~ish large project using them and as I've gotten more comfortable with them I'm doing things I wouldn't have thought possible in #Django 3-4 years ago. I have two Django plugin projects that I want to cleanup and release this month, and full blown SSH shell and an #MQTT ASGI endpoint for #sensor data intake. Both have been well used for a significant period of time now but just need packing and documentation.

Der Wasserstands-#Sensor der Uni #Bonn „ist etwa so groß wie ein kleines Smartphone; dennoch hat es genug Leistung, um aus den Rohdaten den #Wasserstand berechnen zu können“, betont Prof. Dr. Kristine Larson vom Institut für #Geodäsie und #Geoinformation.

„Die von uns geschriebene Software ist #OpenSource“, erläutert Larson. „Sie kann also von jedem ohne Gebühren genutzt werden.“

Also in the box were, 5 optical flow sensors.... ok, was toying with an idea for a robot to track it's movement with the flow sensor. Never got it too work right. So I may have bought a few of these at one time for that project... but Now I don't know what I'd do with them.

We're all pretty good with the definition of 'censure' but that is amazing- since probably only 1% of us have ever looked up the definition in the dictionary.
