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.
Stay informed about the latest radiation levels in northern Germany (in a small town called Schleswig) with this small and tiny bot.
It retrieves microsievert (µSv) data every hour from an #ESPHome device, seamlessly integrated with #HomeAssistant and #NodeRed.
This data is then forwarded to this #Sharkey instance, ensuring you receive timely updates on your social media feed.
Stay safe and stay informed! 
@mmalc clever and great to see in consumer tech but far from the first. Plenty of #domoticz #nodered and #homeassistant users are already scheduling #heatpump water tank reheats for the low point of ( emissions / predicted-efficiency-at-forecast-outdoor-temp ). Actually, is that an error by calasystems? Shouldn't forecast outdoor temp be part of the calculation, as a longer runtime at lower emission rate might mean higher emissions overall?
Both my wife and I have a #LEGO set with a light kit hooked up to our #gaming #PC's. So that when our PC's are on the light kit in the hooked up set is on. Due to the motherboard during #WoL the #USB ports those sets are hooked into are always supplying power. As a result they would always be turned on. So used #nodered with information from a #ESP presence sensor, and information from the #unifi #switch the PC's are connected to to determine if they are on. When they are off the NIC speed is

Fragen an die #eAuto Bubble:
Macht ein Schuko-Ladekabel als Backup im Auto Sinn?
Welche Wallbox sollte man sich anschauen?
Constraints für die Wallbox: Keine Clouddienst-Bindung. Steuerung des Ladestroms via Heimautomatisierung (#Homeassistant oder #NodeRed)
Schonmal danke für input, gerne 
@slightlyoff Out of curiousity…
My workplace uses #React. I gave it a try with one project to get to know it, and while it does reduce a lot of #JavaScript boiler plate, I have found it clunky to deal with.
I've written bare-bones JS for manipulating the DOM… it's tedious. https://github.com/sjlongland/js-calendar just uses the browser DOM functions directly.
Prior to that, we were using #AngularJS (v1, never graduated from that). I never used it enough to really get to know how it worked.
The only other framework I've come anywhere near recently is #JQuery -- in the context of the #NodeRED UI.
Is there an alternate framework one should be looking more closely at?
I have #nodered make API calls to the USGS data.
For any #earthquakes over M6.0 I get an alert via my #Telegram Bot that is built around my Node-RED aircraft data.
Just got an alert of another M6.2 quake alert for Mindanao, Philippines.
Just went through and organized my Home Assistant automations. Since we don't have folders yet, I had to make my own with text. I don't even have that many, but it was such a pain. Any word on some way to better organize these? I'm tempted to move them all into Node Red or somewhere, just for better organization.
@homeassistant @homeassistant@a.gup.pe #HomeAssistant #NodeRed
I ended up using my #NodeRED setup to do the work, since all of the other #MQTT flows are through there. Simple flow to figure out the intended command from the topic, map to the REST endpoint on the Pico's proxy, and that runs the RF TX command to change the light state. I could have potentially done this on the Pico W, but the HTTP-to-RF stuff works fine, so all I did there was a quick #MicroPython 1.20 upgrade, and a bit of tinkering with the network connection code.

Wo: WIR Haus, Wülfrath
OSM: https://www.openstreetmap.org/relation/14772094
Wir spüren die hohen Engergiekosten. Wir zeigen Euch was Ihr dagegen tun könnt.
Alle sprechen über #smarthome aber wir leben es. Habt Ihr schonmal was von #homematic oder #nodered gehört?
Wir haben das #wirhaus im #KreisMettmann in #Wülfrath deutlich optimiert und den Energieverbrauch drastisch gesenkt.
