(This ensures the LED light doesn't completely drain the car battery) To provide an easily accessible live graph (see the bottom of this page) below Tony Walsh (kilnageer@gmail.com) made a NodeMCU based monitor to plug into the LS2024B and provide data to a Blynk cloud display. WiFi internet access was provide by have an LTE Router (with an ex...

Solar powered 12v LED light is now working in our 40' container
