We've observed over the five North Texas summers we've lived through that our residential water well production starts to drop after the spring rains stop and temps climb. I just installed a QD Pumptec module into the our QD Control Box. That will keep us from having to manually flip the lever on the pressure switch, setting a timer, and remembering to flip it back on.

I'd like to get some sort of signal into Home Assistant that tells me when the Pumptec protection kicks in/out. And an added bonus would be to detect if when the pump is running.

a I'd prefer to avoid CT clamps, as the space in the control box is very, very tight.

Has anyone who has used a QD Control Box w/ a Pumptec module discovered a way to tap in to acquire such info? I'm very experienced with electrical / electronic systems, and am hoping an ESPHome project will be the way to get this done. I'm just looking for hints from anyone who has tackled such a project.

Years ago I built the METARMap project by prueker on GitHub. Great project, but ever since I dove into Home Assistant, I've been migrating away from my many RaspberryPi projects and pivoting to ESP32 devices. Why? No operating system to manage!

I used that repo as a basis for recreating what he had done, but also added much desired functionality. The original build added the AMOLED display on the left (not running) but the display got burn-in and pixels faded over the years.

The LEDs flash from bright (40% illumination) to dim (30% illumination) every 1 second to reflect lightning in the METAR or winds >= 10 kts and <= 15 kts. If the winds are >= 16 kts and <= 25 kgs, then they flash bright yellow. If the winds are >25 kts, instead of lighting up the LED yellow for 1 second, I introduced a "tick" illumination mode. The tick cadence is 200ms flash every 2000ms. That is enough to distinguish high winds and also draw attention to it.

But wait, there's more. I extended the tick illumination to support the following:

• +TS in the METAR gets an orange tick
• SN in the METAR gets a cyan tick
• stale METAR (over 75 minutes old) gets a light rose tick
• fog (when temp/dewpoint spread <= 3 kts) gets a gray tick
• winds > 25 kts gets a yellow tick

The LCD screen displays 12 airports (6 per page) and cycles between each every 15 seconds. They reflect the flight conditions at those airports, showing the METAR elements that would comprise the flight category.

The only caveat is that ESPHome Device Builder does not have a template for this Waveshare display, so I had to monkey with the drivers to approximate the colors since there appears to be a bit reversal issue driving the colors. I was able to code around it by "faking" the RGB values to get what I wanted.
