Access battery level

[thegecko]

The current Rocky API doesn't mention a way of getting the current battery level, is this possible?
If not, would the watchInfo object be the best place to expose it?

There's currently no API that exposes the battery level. Following the idea of embracing web standards, our current plan is to implement the battery status API.

Great, how can I help?

First: Confirming that this would solve your particular use case.
Second: We still need suggestions for non-standard APIs, e.g. Health Data such as step count or heart rate.

I know, I am highjacking this Issue a but, sorry – but you were asking, so ¯_(ツ)_/¯

I want to show a battery level indicator on my watch face using rocky. The API is of less concern than the data, but following an existing spec. is always sensible.
The proposed API will allow a callback to be registered which can update a value on change, so this will satisfy my use case.

This should probably be on another thread, but one approach could be to have a standard eventListener model for when an established API doesn't exist.

You could also request data from known stores, similar to the characteristics on BLE.

My question about helping can also be read as:

Please show me an existing example of exposing an underlying data source through rocky which I could use as a template.

P.S. Looks like you will need to implement promises, too :)

Have just started using rockyjs and agree with @thegecko that non-standard APIs such as step count or heart rate are implemented as on callbacks, such as the existing memorypressure example.

I'd like to help too if I can, particularly as I note there's no current support for bluetooth connectivity status either.

Great work with rockyjs!
