  Project mention: Introducing my TallyWhacker. A new smart home device designed souly to piss off my upstairs neighbor. | reddit.com/r/arduino | 2021-06-04

  Not OP, but I‘m assuming this is using ESPHome With it you can flash ESPs with custom firmware that you can configure through a YAML file. It uses MQTT to talk to HASS, usually mosquitto.

• IRremoteESP8266

  2 1,771 8.3 C++

  Infrared remote library for ESP8266/ESP32: send and receive infrared signals with multiple protocols. Based on: https://github.com/shirriff/Arduino-IRremote/

  Project mention: Making dumb LED strips smart. | reddit.com/r/esp8266 | 2021-04-21

  Your starter for 10 on ESP8266 and IR is crankoldgit's library When you say transistors I hope you mean big beefy power transistors or mosfets? The current led strips use can be surprising, my 4.5m RGBW 12V strip draws 9A at full brightness and the similar length WS2812 would pull 15A at full brightness if my software didn't restrict it. Do run the numbers on power consumption in regard to your switching device. It's possible to do what you want with the existing receiver but as you've already found it's not that straightforward and requires a good magnifier and enough knowledge of electronics to decipher the circuitry before you could modify it, If you want a reasonable size prebuilt RGB controller the generic H801 boxes are cheap, readily available, ESP based and easy to flash your own code to. The other possibility is to IR enable your ESP8266 using a simple IR receiver like one of the TSOP series, the filters and amplifier are built in and as it's just a 5mm package it's easy to mount it where it's convenient. That way you can have the option of IR or WiFi control, I occasionally use an old IR remote as buttons are often more convenient than web pages for controlling things, in my case the remote talks to an IR to WiFi bridge I built using the library linked. above.

  Maybe. Depends on whether the data between the Bluetooth pairs are encrypted. You could checkout some ESP32 Bluetooth sniffer examples, this may help you identify the camera trigger within the data stream. This may help https://github.com/justcallmekoko/ESP32Marauder let me know if you crack it :)

  Project mention: Google Cloud IoT recommendation for streaming data from serial device, then reading in near real-time? | reddit.com/r/googlecloud | 2021-05-01

  Thanks a lot - yes, RTDB is my main DB and I'm a fan. My question is the best way to get data from an ESP32 directly into Firebase RTDB. I was going to try this repo, but was wondering if there was an alternate way to do it using Cloud IoT (perhaps too heavyweight for my needs though?)

  Arduino web server library.

  Project mention: Vanilla Javascript OTA | reddit.com/r/esp32 | 2021-04-14
