Hardware

Hello,

I’m would like to know what energy my solar panels produce.

In my garage I have 3 counters like this :

Is there hardware out there to read this info ?

Or if you have an other solution, feel free to tell me.

Thanks !

Looks like there’s a pulse counter possibility too? Maybe something like Youless might work if there’s a blinking led.

Well noticed, didn’t even see that pulse :grinning:

I presume that will be the way to go…

Is this available commercially or is it best to make it myself (ESPHOME)…even if I never did that…

The youless is commercially available in the Netherlands, but maybe not outside. Making one using an esp would be a lot cheaper, and you could combine the three instead of needing 3 separate.

Something like this:

Seems that will be my first DIY project :grinning:

Looking at these photoresistors, could the XH-M131 5V (Xh-m131 Dc 5v 12v 24v 10a Light Control Switch Photoresistor Relay Module Detection Sensor Brightness Automatic Control Module - Integrated Circuits - AliExpress) be used with an esp32 ?

If so :

  • ground (gnd) pin on the ESP32 board to ground on the Photoresistor (3 wires seen 3 Photoresistors)

  • the 5v pin on the ESP32 board to vcc pin on the Photoresistor (3 wires seen 3 Photoresistors)

  • suitable GIPO pin on the ESP32 board to the data pin on the Photoresistor…where is that ?
