≪ So weit, so gut ≫

Die ersten Experimente und Tests mit einem ESP32-C3 Mini verliefen erfolgreich.

Dass es irgendwann eine neue Mesh-Software geben würde, hatte ich ja schon länger erwartet, aber dass diese sich nach dem Start dann so schnell weiterentwickelt – ist schon großartig.  👍

My "Buurtmelder" (“Neighbourhood Notifier") project is coming along nicely.

It's an ESP32/RP2040-based device with a 433Mhz receiver that can be used to sniff RF codes sent by (cheap) home alarm systems and broadcast alarm activations to the entire neighbourhood (because neighbours are always closer than police in case of emergencies).

Initially it used LoRa for broadcasting, but because it has some reliability issues it now uses MQTT-over-WiFi with a LoRa fallback.

You can also add "beeper satellites” around the house so you don't have to be near the terminal to see if there's an active alarm. When there's an alarm, the main terminal will use ESP-NOW to tell the beepers to start beeping.

Somewhat seriously considering implementing channel scanning in ESPHome's ESP-NOW component. Right now it's a bit of a PITA to have to manually set the channel, especially if you want to make devices that should work in random WiFi network.

I guess I first have to finish the ESP-NOW encryption PR I was working on... 🥴

Wusst gar nicht dass man den OpenSource #ESP32 Flightcontroller https://github.com/rtlopez/esp-fc mit #BetaFlight Konfigurator und auch mit #ESPNow / #ELRS zusammen nutzen kann

Kann man sich hier im Video anschauen:

Working on encryption support for ESP-NOW in ESPHome: https://github.com/robertklep/esphome/tree/esp-now-encryption

I’ve reached the point where configuration and compilation isn't failing anymore 😅 So tomorrow I'll check and see if it actually works as intended, and then hopefully soon a cheeky PR.

Working on a distributed alarm system, where an alarm (burglar, panic, fall, etc) is propagated to the rest of the street, using ESP-NOW between the ESP32C3 and the Seeed SenseCAP Indicator, and LoRa between the Indicator and other Indicators running at our neighbours’ houses.

The ESP32C3 is going to be hooked up to a cheap alarm system (hooked up to the siren output, probably); when the alarm sounds, it will send a message to the Indicator it's paired with, which in turn will broadcast the message across the rest of the street.

Initial tests show that the Indicator should have a range of at least 500m, which is more than enough. If not, I can always look into rebroadcasting.
