ESP8266 Community Forum

Hi,

I need help in developing an ESP 8266 or other ESP Chip powered Power Bank Battery Monitor.

I have a use case where a Baseus 30000 mah power bank is powering an IoT device.

I need to monitor the battery of this Power Bank especially when say it is 25% it should send an alarm to Homeassisatnt.

Can someone please guide me on the direction I should take?

I await your support.
