Looking at the code to better understand how CoopCommand interfaces with the ESPCam, I thought about the following. The ESPCam board can also be flashed with ESPHome. ESPHome is fairly simple to program so that it interfaces with CoopCommand over the UART bus (as it is working now). This would integrate seamlessly with my Home Assistant.

This made me think about making CoopCommand more dynamic by sending the sensor readings: temp, humidity, watertemp, illuminance) every 30 minutes or so. I could then show the cam feed and sensor information on a nice card in the Home Assistant interface.

Have you considered using ESPHome => https://esphome.io/? It might make it easier to deploy ESPCam than using Blynk. Curious to hear your thoughts on this.

I'll start some experimenting of my own with ESPHome code in the meantime.
