Anker’s F3800 (in my case non-plus) is a great home backup/mobile backup battery from the specs but not having any way of getting global notifications defeats it’s use as backup. Now, I am using it to load shift, which is distinctly different from home backup. Load shifting requires more data but even if you’re only using it for backup it is still too easy for the storage to run out without strong enough notifications for a user to take action.
Of course my preference is integration with Home Assistant. There may be ways of hacking this physically, there have been attempts with software that I’ll follow up on, but it seems like physical additions (not necessarily modifications) might be the best method.
More soon.
Updated and Retried with Firmware v2.4.0: 10/24/25
