So the BMT01 appeared in the offer…
I’ll say that I was a bit surprised by this product… I didn’t know that potential customers of Sonoff products needed something like this.
A lot of other solutions would probably be on the list to create, but something like this… 
There must be a big demand for something like this. 
The idea of using this device for something more than meat, even as some kind of temperature measurement module and introducing it into scene automation will probably not be possible because communication is only via BLE and locally per app, if I understand correctly.
Although with a little effort it would probably be possible to create something using Macrodroid… although it depends on how alarms/notifications are implemented.
Because there is no point in counting on the ewelink app finally starting to have intent broadcast.
I wonder what the sales results will be in the 6-month period.
