Kincony, you absolute legends. This is going right into my apartment build. #ESPhome #HomeAutomation

Bei #Hornbach gab mal ein geniales #Bewässerungssystem der Eigenmarke for_q, bei dem der Steuercomputer und die Ventile physisch getrennt waren und mit einem Käbelchen verbunden wurden. Genial deshalb, weil es Solid-State-Ventile waren, kurz mal -6V/+6V anlegen, und sie machten auf oder zu. Statt des originalen Steuercomputers einen #ESP32 mit #ESPHome rangeklöppelt, hatte man eine MQTT-Bewässerung.

Bei den neuen Geräten sind der Computer und Ventile untrennbar in einem Gehäuse.

Well... it's a start.

I'm looking to #degoogle the voice control part of my home smarts. It's going to take a while before everything works as it does now, minus google.

I'm doing the weekly home IT update chore this morning. I wasn't home last week, so there's a lot.

- OPNsense minor upgrade (save 25.7 for next week)
- New firmware for two Omada access points
- PI-Hole 25.7
- Home Assistant Core and ESPHome Builder
- Karakeep 0.26.0

Then I'm going to take the first steps in the TrueNAS Core -> Scale migration. That'll go on for days if not weeks.

Kennt sich jemand mit C++ im Bereich Lowlevel im Zusammenhang mit esp-idf insbesondere rmt für #esphome aus?
Ich würde gerne ein Projekt auf den aktuellen Esphome Stand bringen, damit es auch wieder kompillierbar ist. Ich verzweifel an RMT und könnte da Hilfe brauchen.

Gerne teilen und sich bei mir melden.

Gonna re-post my guide for anyone with a Mitsubishi Electric split-system Air con from the last 10ish years, on how to integrate it with Home Assistant/ESPHome for $20 with one extremely easy, reversible, safe hardware addition!
I've been running it without issue for 9 months now, and others have successfully followed my process.

I've used the integration to do stuff like automatically turn off the aircon an hour after I go to sleep, and put an automation so if we leave the house, it'll turn the aircon off in case we forgot. I also built an automation to run it in fan only mode on low for 15 minutes after being on cooling, to evaporate the moisture inside that otherwise leaves to building up mould.

Was für static website generators sind denn gerade hipp, bzw was ist vielleicht in einem Jahr noch nicht legacy
Oder doch lieber gitlab pages?
Möchte mal meine #HomeAssistant / #esphome Projekte wo zusammenschreiben
Bei esphome macht es wohl Sinn den code und docs in ein Repo zu werfen.

Integration des Multical 303 Wärmezählers in Home Assistant via Wireless M-Bus

My latest #homeassistant #esphome project: A parking assistant for the garage.

Our garage is fairly small and the only spot for the refrigerator is against the back wall. This makes parking challenging, since there's only a few inches difference between clearing the garage door and leaving space to open the refrigerator door.

I designed this device to make it easier to park the car in the sweet spot. Design details to follow in the next post...

Water tank level sensor: 4–20mA current loop, ESPHome, and Home Assistant

https://blog.narf.ssji.net/2025/06/30/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.

I've spent ages trying to figure out why my #ESPHome devices wouldn't connect to the #Cisco AP2800s.
Mobility Express -> Wireless Settings -> WLANs -> (edit SSID) -> Advanced tab. Turn off "Client band select" and "Client load balancing".

Explanation in the ...

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 think it's probably time to switch from #Tasmota to #ESPHome https://github.com/arendst/Tasmota/discussions/23542

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

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.)

Looks like I found three things that my Raspberry Pi 4 are struggling with: building stuff on my Forgejo builder, building ESPHome firmware, and running Ollama for Home Assistant Voice.

I'm not trying to throw shade on Raspberry Pis, not at all. Love them. But it seems like I need something more powerful for those corner cases that I've been finding.

Maybe a Pi 5?

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.
