Neato Saugroboter mit ESP32 und Home Assistant weiter nutzen

> Besitzer von Saugrobotern des Herstellers Neato stehen vor dem Problem der Server-Abschaltung, was die smarten Funktionen der Geräte quasi nutzlos macht. Wer seinen Roboter nicht entsorgen und durch ein teures Neugerät ersetzen möchte, findet im Open-Source-Projekt neato-connected einen interessanten Ausweg, das allerdings einiges an Wissen erfordert.
Wondering if fedi has any DIY indoor air quality/co2/voc/temp/humidity device recomendations?
I found this project, checks all the boxes + cute compact design, but sadly no longer maintained... I'm hesitant to order parts/PCB.

This tiny custom ESP32-C3 board is about the size of a USB-C connector (and is attached to one). Other features include a 32-bit RISC-V microcontrollers, WiFi 4, BT 5.0, and a single GPIO pin. It measures just 9.85 x 8.45mm. https://www.cnx-software.com/2025/11/21/ridiculously-tiny-esp32-c3-board-features-usb-c-one-led-and-a-ceramic-antenna/ #pegorKF32 #ESP32 #DevBoard

Working on BLE packet sniffing and transmission for MeshTNC, bc who doesn't want to do APRS or meshcore over BLE advertisements 😉
My quick hack feels promising so I think I'll clean this up and PR it.
First things first, I want to make it so that the ASCII CSV output format for BLE packets roughly matches LoRa packets.
Every packet gets an arrival timestamp, type, RSSI and SNR values. Followed by whatever payload.
In the case of BLE packets there's also a 6 byte MAC so I slap that infront of the payload.
There's no SNR data for BLE so that's always 0.0. But the RSSI is good.
Here I was thinking the KISS protocol support was going to be hard ✨
Actually this flew together, mostly bc @meph already did all the hard stuff on KISS handling.
So just check which output mode we're in and yeet the data at the BLE data KISS port.

Avete presente quelle tv nei supermercati che dietro hanno i led che illuminano la parete in base all'immagine? Ecco, ho trovato il modo per ricreare lo stesso effetto.
Il tutto funziona con un #ESP32 con sopra installato #WLED e una striscia #led #WS2812b e un semplice programma multipiattaforma chiamato Hyperion che si occupa di catturare l'immagine a schermo e trasferirla a WLED. Trovate le guide per entrambi ovunque nel web

Daikin enshittified their aircon firmware in one fell swoop with their 2.9.0 (IIRC) update, breaking the local API – which worked perfectly well with #HomeAssistant – and forcing people to use their (shitty, natch) app instead^
their shitty app periodically forced you to apply their “optional” firmware update (even when you’ve explicitly set the “automatically upgrade firmware” toggle to the “fuck no” position) by preventing you from even using the app to control your device until you submitted to installing the upgrade (i.e. they bricked their own app until you agreed to brick (more or less) your aircon) 😡🤬
in the case of the #Faikin #ESP32 module though, it has to be installed inside the aircon head unit, which involves touching (in AU) 240V mains power – and in AU you can’t do that (legally) unless you’re a sparky 💁♀️
plus, I expect that an insurance company might decline to pay out if your house burns down as a result of a fault in your aircon & they discover you had a non-vendor-approved hardware mod installed 😤
it’s neat little bows all the way down… 😕

^ which also strongly encourages you to sign up for & use their cloud platform so you could send a packet around the world to change the temp on your aircon & if you lost internet connection, welp, sucks to be you 💁♀️

The solution to a lot of this might be open hardware. A garage door opener isn't that fucking complex. It should be possible to build a prototype with a micro-controller and a couple of relays. Unless Chamberlain wants to make an argument that looking at the leads of a motor are proprietary, which would be absurd (and probably unsuccessful). Once that's done, we have the tools to create an open hardware controller on a custom PCB at a reasonable cost. Then one rips out the proprietary controller, drops in a replacement, and carries on. I seem to recall a group that was working on this with the infamous John Deere farm equipment. No right to repair? Well then, how about a right to replace?
Edit: fixed weird duplication of the text!
