≪ 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:

Seems to be working. I’m going to test it with my ongoing project and it everything works as expected, a PR will follow.

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.

Некоторые варианты практического использования протокола ESP-Now в самодельных устройствах

Если вы хотите получить для своих самоделок достаточно быстродействующий (до 1,5 Мбит/с), дальнобойный (300+ метров), и, в то же время, энергосберегающий (50 мА во время передачи) протокол, то "ESP-Now" - ваш выбор! В этой статье мы не будем разбирать подробно все технические особенности протокола, так как для этого есть соответствующие спецификации, - вместо этого мы остановимся на более интересном: его практическом применении и, в общем, ознакомимся с некоторыми особенностями протокола.

We now have #ESPNow #WiFi capability for @microblocks

The receiver hardware consists of:
- ESP32 D1 mini board
- RS485 transceiver
- XLR socket
- Big power bank
- WS2812 LED ring I had laying around to debug the effects

It receives the button events via #ESPNOW, processes them to light effects and outputs #DMX to the RGB spotlights (and the WS2812 LEDs).

I finished putting everything in a stylish cardboard box at 7am on the day of the event and went to sleep :P

#Grobpfottaster2Light #ESP32

Software-wise, the buttons are pretty simple.
I used the #ESPNOW protocol, ofc, because the actions had to be transmitted quickly and without using much power.
The button simply transmits its state (and battery level). So during a normal press "cycle" it sends the packets: 'pressed', then 'held' (repeated), and finally 'released'.

I tried to optimize the power usage as much as possible.
Disabling the ESP-NOW receive already dropped the idle power usage from 80mA to 20mA.
Going to light sleep between button presses dropped it further to around 0.6 mA.
(Deep sleep didn't work correctly with the chosen wake-up pin and would've been overkill for "has to survive an evening" anyways. Even light sleep isn't really necessary [foreshadowing])

MeshCore bringt zusammen, was zusammengehört

LoRa-Mesh-Netzwerke sind mittlerweile doch sehr bekannt, aber ein ESP-NOW Mesh ist noch wirklich selten anzutreffen. MeshCore eröffnet die Möglichkeit (derzeit noch in einem recht frühen Entwicklungsstadium) beide Netzwerke miteinander zu verbinden und zu nutzen. Die ersten Tests sind sehr vielversprechend 😀
