Wondering how to make the battery last longer on my #ESPHome display thing. I think I want to make it sleep pretty much most of the time, except a couple of fixed times a day, or if I press a button. Somehow!

Mein CO2 Sensor hat jetzt einen Batman Modus.

(Manchmal sind die Sensoren noch nicht initialisiert, wenn das Display zum ersten Mal nach dem Booten aktualisiert wird. Dann liefern die den Wert NaN not a number.)

Water tank level sensor: 4–20mA current loop, ESPHome, and Home Assistant
Our house water comes from a rain water tank. I built an ESPHome device, based on an Olimex ESP32-PoE2, to interface a 4-20mA current-loop liquid pressure sensor, and keep track of the water level in Home Assistant.
All switches are connected to an #ESP32, which is connected to my #HomeAssistant over #ESPHome. I am just using a binary sensor. Like this I can do this very easily and it is nicer to integrate with lamps etc. The LED-Strip on my mic arm is powered by another ESP32 running #WLED by the way. The ESP gets its power even from the other ESP across the desk.
I wrote another thing about home automation and alarms and stuff.
This time I talk about planning a basic level of hardwired security into my apartment, and what prep work has been necessary.
I'm looking at setting up an auto-feeder for my #aquarium. I would like to find one that either has a native #HomeAssistant integration, or is at least easy to override it's native controller with an #esp32 brainworm I can run #esphome on.

Ich habe das #blinkyparts Unicorn mit einem ESP8266 und einen Transistor per #ESPHome mit #homeassistant steuerbar gemacht. Jetzt blinkt es, wenn der Bewegungsmelder an der Gartentür auslöst und ich weiß das ich die Katzen reinlassen kann :) Danke an die lieben Menschen im @chaospott die mir bei der Erweiterung geholfen haben. Für mich war es das erste Mal, dass ich bei einem Lötprojekt von der Blaupause abgewichen bin
I've been doing a bit of @MCQN_Ltd project archaeology of late. As a result I'm rather pleased with getting this LED to blink in response to the Mastodon API
@courtney I use #homeassistant so I prefer #esphome
Yesterday, I had a programming jig 3D printed for this Sonoff S31 device. Looking good!
The contact pins should be arriving this weekend. Assuming the assembly goes ok, the next question is ESPHome or Tasmota? (I'm leaning towards the first.)
The Sonoff S31 with native firmware has been a terrible disappointment. It still requires the app to pair, pairing is insanely hard, and then when done, it appears that Home Assistant (using a HACS integration) doesn't see it. (I'm guessing the issue is getting mDNS to traverse my VLANs.)
I think I'm going to need to flash a firmware to use this. So onto the tail of the project queue it goes.

Sad that I missed attending a #HomeAssistant community day event. But glad that the reason was because I took the chance to install the first sensors in my bathroom renovation, during a pause in construction work.
Having everything open is a once in a quarter century chance to hardwire in leak detectors beneath bath, sink, and washing machine. (All going back to a central ESP32 board).
My comms and sensors center is running strong!
From left to right:
Seeed studio ESP32C3 with BME280 running #esphome
RTL-SDR running #ADS-B data gathering
Seeed Studio LoRa running #Meshtastic
All devices connected to a PoE powered #raspberrypi4 (the LoRa and esphome just use it as a USB power adapter)
Thanks to PoE I need to only have one cable coming from my switch.
Now that I could just plug the board into a random USB power adapter, and the LED strip into the board, the only remaining piece was software. Since I was relying on #ESPHome, it was just a matter of setting up my #HomeAssistant as a time-source and wiring a loop to switch LEDs every second. The only tricky part was translating indices to take into account LED strip being a single continuous sequence of lights arranged in a zigzag manner. #IndicesOfTime
For the hardware, I knew I wanted to go with ESP32. It's ubiquitous and cheap. While I have some experience programming for it, my intent was to actually avoid need to do so thanks to the fantastic #ESPHome. It's surely an overkill for this project, but it would just take few dozen lines of YAML config and would give me Over-the-Air updates, logs and what not. So here I am, looking for a way to drive WS2182 with an ESP32 controller. #IndicesOfTime

Die sind nur die #SpitzedesEisbergs
#Saugroboter #WlanSteckdosen , bzw. generell #Smarthome - Produkte aus Fernost funken alles brav "nach Hause".
Es gibt aber zumindest für Tüftler oft Alternativen aus dem #FOSS Bereich.

Hacked the firmware on a #geekmagic smallTV and got #esphome #homeassistant running on it - wrote new software that serves up quotes from #therules by #sistercoritakent and#johncage #obliquestrategies by #peterschmidt and #brianeno and rules from the notes on the studio walls of my partner to make special birthday present for her - ‘mouseTV - 192 inspirations by artists for artists’
My laser saver for yesterday, May 4. :-)
Building an ESPHome multi-sensor: Bluetooth proxy (mainly for Bermuda BLE trilateration), temperature, humidity, and motion sensors.. I used an D1 Mini ESP32 AM313 + BME280. Currently testing the HC-SR501. It is larger, but the sensitivity and delay can be adjusted.
