Dec 10, 2020 · Past days I learned a lot about the ESP32 microcontroller. Internet taught me how to connect an LCD to the controller and how to read analog inputs. I installed the Arduino IDE with the Espressif files to be able to program the ESP32 development kit in "C". At this moment I have a working prototype of a CO2 sensor circuit. I used an MG-812, CO2 ... 1. ESP32-CAM is a WIFI+ Bluetooth dual-mode development board that uses PCB onboard antennas and cores based on ESP32 chips. It can work independently as a minimum system. 2. ESP integrates WiFi, traditional Bluetooth and BLE Beacon, with 2 high-performance 32-bit LX6 CPUs, 7-stage pipeline architecture, main frequency adjustment range 80MHz to 240MHz, on-chip sensor, Hall sensor, temperature ... The first event value is the task index, the second event value is the return value of the PLUGIN_INIT call. The task index can be useful to store in a variable so the task index of a specific plugin like the dummy plugin can be stored to keep rules exchangeble among nodes regardless the order of tasks.
Problems created by water penetration can also be stymied by establishing a drip loop on any and all cables. This is an easy process; just give the cables enough slack so that instead of travelling in a straight line from one destination point to another, they droop down, creating a low point that water can drip off of.
The ESP32 is a no-brainer for me because I’ve used it before on small projects. They are small, are easy to program (Arduino compatible), have a lot of power (240MHz dual-core processor, 520K memory) and have built-in WiFi which means they can directly connect to the internet. This was on a ESP32 development board. I tried to load tasmota.bin using tasmotizer, it failed. I suspect if you try loading Tasmota via the Arduino IDE it might work, or at least guide you as to ...
