> If your network hardware allows it, you should pin the device to the closest one.
In Wi-Fi it's always the client's choice on where to connect to at the end of the day, any hacks the APs try to do to steer clients are "suggestions" at best and "signal ruiners for everyone" at worst. You may be better off specifying which specific AP you want to connect to by specifying the BSSID argument in the WiFi.begin() call client side https://github.com/espressif/arduino-esp32/blob/master/libra...

esphome
ESPHome is a system to control your ESP8266/ESP32 by simple yet powerful configuration files and control them remotely through Home Automation systems.
Instead of manually programming the microcontroller, I'll run ESPHome on it, for two reasons:
-
OpenMQTTGateway
MQTT gateway for ESP8266 or ESP32 with bidirectional 433mhz/315mhz/868mhz, Infrared communications, BLE, Bluetooth, beacons detection, mi flora, mi jia, LYWSD02, LYWSD03MMC, Mi Scale, TPMS, BBQ thermometer compatibility & LoRa.
-
IRremoteESP8266
Infrared remote library for ESP8266/ESP32: send and receive infrared signals with multiple protocols. Based on: https://github.com/shirriff/Arduino-IRremote/

Project mention: Balcony solar taking off: 1.5M Germans have them there must be something in it | news.ycombinator.com | 2025-02-10
There's a link to a pdf manual for what appears to be a fairly common one here: https://github.com/tbnobody/OpenDTU/discussions/855
The inverter is designed to stop feeding power if the grid drops off.

Project mention: Twonkie: A USB-PD sniffer/injector/sink based on Google's Twinkie | news.ycombinator.com | 2024-06-24
Yep. That's exactly what I am looking for. Use USB-PD to charge small electric vehicles in a standardised way ;) See https://jan.wildeboer.net/2024/06/Charging-SEVs-A-Modest-Pro... where I describe the concept and https://github.com/manuelbl/usb-pd-arduino/wiki where there is Open Source code (and schematics) to do PD sniffing and sink negotiation.
