Where can I find freelancer to develop some change to the original device based on 51822?

The change is adding a motion sensor to a gpio and wake up the device each time it moves.

[Nguyen Hoan Hoang]

Try this product instead.

Hi Avip!

You can take a look at the "Advertising" part of our blog here on DevZone.
That might also be a better place to put a post like this.

Best regards,
Joakim.
