Ring doorbell install and relay

The electrical install instructions for the Ring Doorbell maybe could be a little easier to find  ? 

So will give some links where you are connecting to

1. Internal doorbells
2. No internal doorbell but charging the battery
3. External relay, triggering "anything"
4. Wireless relay

Ring Device manuals are found here.

Scenarios 1,2
The most scenarios for 1 and 2 are covered here

Please note that if you don't have any internal doorbell and are using an AC transformer charging the battery, you have to use a resistor, 25 Ohm 50 W, to limit the current. This is due to that when pushing the Ring button you will make a momentary short circuit.

Check here the different Ring models specifications using different transformers.

Scenario 3
If you want to trigger another gadget, when somebody is pushing the Ring button, it's smart to use a relay so you don't have to bother about electrical characteristics. In these videos different solutions is discussed.

Scenario 4
Sometimes it's impossible to draw a wire to the relay so a NodeRed flow which is used together with HomeKit(Homebridge) to wireless solve the problem. (Off course there are other open source applications, for example Home assistant, that could do the same job.) 

The flow to the right senses when the Ring button is pushed and will activate the relay, Ring_8750, during 5 seconds.

Prerequisites

Ring doorbell

HomeBridge emulating Apple Homekit

NodeRed with node "node-red-contrib-homebridge-automation" installed

Some wireless relay, could be Shelly 1
