I'm dipping my toes in #esphome reading the documentation, and it's awesome! It supports an huge quantity of #sensors, the data read from the sensor can be filtered and manipulated, it supports a lot of #displays and #graphic libraries! It is extremely well integrated with #homeassistant as it's the main use case. It's very flexible! I can see how I could do other little projects with this, but unfortunately it seems not to expose a standard REST Api...
They say the native API "is based on a custom TCP protocol using protocol buffers. You can find the protocol data structure definitions here: api.proto A Python library that implements this protocol is aioesphomeapi.", so I should be able to interface with it, but it isn't very interoperable (and it probably isn't meant to be)...

Over the past few days, I "channeled" my inner nerd into building an automated radiation detection system using open-source tools.

The device combines an ESP32 running #ESPHome for sensor data collection, my #HomeAssistant for centralized smart home integration, and #NodeRED for automating hourly Fediverse updates via a bot account

@Radiation_SL (since this Geiger counter is located in northern Germany ( #Schleswig )

Technical Breakdown:

Sensor: Radiation D-v1.1 (CAJOE) - radiation detector

Connectivity: ESP32 transmits via Wi-Fi to Home Assistant

Case: #3dPrinting the case (photo) - base is black and the lid is blue and shows the logo of "Fallout" (pc game/ TV series)

Automation: Node-RED flow formats data into ActivityPub messages

Decentralized Sharing: Posts include μSv/h readings

While this started as a hardware tinkering project, recent global events — nuclear rhetoric in conflict zones, aging power plants, and insufficient transparency in environmental monitoring — made me realize decentralized citizen science could play a crucial role.

Open-source tools eliminate single points of failure, and Fediverse integration ensures censorship-resistant data sharing.

Feel free to follow my bot account I mentioned above, if you are interested.

If I can find some time I will write a blogpost about the build process and link it in the bio / or just toot about it.

A black box with a blue lid. In the lid is the yellow logo of the pc games "Fallout". The box stands on my desk.
Screenshot of my HomeAssistant panel. It shows the Ionizing Radiation Power in Mikrosievert per hour. The readings are between 0.09.and 0.21 - the line goes up and down and up and down and up and down...

@3dprinting Now I need to wire up the rest of the electronics. MOSFET to switch the Peltier, 12V power to the Peltier and fan, 5V converter for the ESP32, GPIOs to the MOSFET's gate and the fan's PWM and tach signals, and an I2C connection to the external temperature/humidity sensor.

I should draw up a schematic in KiCAD just to keep track of all the connections. I haven't used KiCAD in years...

@3dprinting I drilled into the cold side heatsink and inserted the temperature probe. I got it into ESPHome and Home Assistant.

The first dip in the graph is with no thermal paste; the second is with paste. It drops a lot faster and further with paste. I stopped the second run at -13℃. N.B., there is no airflow through the heatsink yet. It won't get so cold with airflow.

So this is encouraging.

🧵 14/N

A hole has been drilled through the first four fins of the heatsink, and the cylindrical temperature probe has been inserted. There is some thermal paste on the probe. The heatsink is installed into the dehumidifier, but is not covered.
The partial cover is on. The ends of the heatsink fins are showing, and the wire of the temperature probe is coming out of the top of the assembly. (Left side, actually, but it's laying over on its right side.
A graph from Home Assistant showing temperature over time. There are two temperature drops. In the first, the temperature starts at 23 degrees Celsius, then falls asymptotically toward -0.5 degrees over 11 minutes. On the second test, the temperature falls from 23 to -13 in less than three minutes. It was still falling fast when I stopped the test.

@frederic I flashed a NsPanel, 2 buttons, touchscreen with #esphome. Integrated with HA.
Easy setup and you can set the intensity and color via the screen. It show the temperature and also other data whatever you like.

Not directly an answer but in this way it is acceptable for other users in the house…

Afterwards I checked my #HomeAssistant energy monitoring data (provided by an Emporia Vue 2 flashed with #ESPHome). The yellow line is the voltage on one 120V leg from the transformer (the one that was going to burn up), and the blue line is the voltage on the other 120V leg.

The three sections of the graph are during the problem, while the power is out, and after the new transformer was installed.

Graph of the voltages over time of the two 120V legs in my house. One leg's voltage fluctuates significantly throughout the day and also drops measurably. In the latter part of the graph, the voltage on both legs is very consistent.
