HHCCJCY01HHCC: controlling the LED?

[danergo]

Anyone found out how can we control the LED of this plant sensor?

I will create some bt sniffs tomorrow to find out what the original app uses when identifying these devices.

However it would be extremely useful if we can upload some threshold data, and have some alarm activated:

blink the LED when moisture goes below 10%

In case we can do this only with an active connection, that would drain the battery within a very short time.

Did anyone investigated and found out something like this on these sensors?
