Stand-alone Bluetooth smart plug with timer and energy monitoring

[weary niche]

Hello, do you guys know any Bluetooth smart sockets that have both timer and energy monitoring features. I cannot seem to find anywhere, google only shows me ones with only timer feature. And almost all of them are out of stock. It looks like Bluetooth ones are in decline

Wifi is not always always available and needs to be set up everytime for new wifi network. So it is out of question.

I plan to use one for traveling. And it's easy to set up macros in android.
For example, I could make charger delay charging pev after phone disconnects from it and connects to Bluetooth smart socket. Just to let batteries warm up since weather is quite cold here.
