Wiring
If you supply the Wemos externally with power: NEVER use for example 5V output of the battery or similar. ALWAYS use a separate USB power supply (cell phone charger). Otherwise there is a risk that the Wemos will be destroyed!
We assume no warranty and / or recourse for destroyed devices.
Pin D8 of the Wemos is for the wake. Please connect according to wiring, NEVER connect the pin directly to the BMS!
Pin D5 of the Wemos is for the relay. However, this requires a relay with driver module. NEVER connect a "naked" relay to the pin!
We assume no warranty and / or recourse for destroyed devices.

🚨 For a given occasion: 🚨
No matter whether you have a self-made board or one of our boards. Never (never never!) supply them either via the BMS externally with power supply via the Wemos, nor with several BMS connect several Wemos via the same power supply! If you connect batteries in parallel, you will build a GND loop. If you connect batteries in series, you short-circuit the batteries (minus of battery 1 is not equal to minus of battery 2, etc.).
If you don't have the willingness to tinker and learn... TURN BACK!
This project is not a commercial product and support is limited. You have to be willing to research and solve potential problems yourself.
