Solar Assisted Link
This makes an excellent link, and requires no external power source (except the sun). It does allow you to charge from external power if you need to.
The link has a simple on/off switch. Once it's onboarded to your cluster, simply turn it on and you should see it recognized by your other devices within minutes.
