I’m using my battery to power my home office setup, but I keep running into the same issue - I never know when it’s about to die unless I constantly check the app/front of the device. It’s really annoying losing power because I didn’t realise the battery was draining so fast.
I needed a way to see exactly how much power is left to create an automation if its running low up until the overnight charge kicks in.
Using data from a post over on reddit to get id’s
Ive managed to hack together a working YAML script to open the F2000 up to Home Assistant via ESP32 WROOM device + Nice of Anker to supply a USB socket to self power the device 
Getting my MAC is a challenge I found it using one of the android Bluetooth Scanners as I couldn’t find it using Nrf Connector
The YAML
Create a new device in ESPHOME and that will generate the upper section needed then paste the code after ‘captive_portal:’ (this also will allow you to rename the device in your setup)
