Hard wire Ring Video Doorbell 2 with Ring transformer

I just want to share my recent experience (August, 2019) installing and troubleshooting my install of the Ring Video Doorbell 2 with the Ring transformer. - I first purchased a 24 VAC transformer sold on Amazon by a third party. Wired it up, but it did not power my Ring VDB 2. - Spoke to a very good support person at Ring and found the Ring document indicating that if you are hard wiring the Ring VDB 2 without a mechanical or digital doorbell already installed at your house, you needed to solder in a 25 ohm, 50 watt wire wound resistor into the circuit. The document gave links to suppliers of the resistor. I bought mine from Digikey. I returned the transformer sold on Amazon and bought the Ring transformer off their site. - I soldered the resistor into one of the conductors (either one is OK) coming out of the Ring transformer and used wire nuts to the solid core wire I had routed from my Ring VDB 2 into the house. I then plugged in the Ring transformer. - Yikes!!! Smoke coming from the resistor and it became red hot! Also, the Ring VDB 2 was not indicating hard wired in the app and the white LEDs were not being powered on. - Called Ring support. Polite, but no help. - So, I thought, is my problem the transformer, the resistor, my wiring or what??? - Eliminated transformer as problem by measuring with my multimeter 27.7 VAC power coming out. Good. - Eliminated resistor (after it cooled down) by measuring 25 to 26 ohms with my meter. Good. - I was wondering if my soldering job was up to standards, but doubted that it was my problem. - I then realized, the wiring coming from the transformer is stranded, perhaps 20 to 22 gauge rated. The wire to which I connected the transformer wire (after the resistor integration) was solid, 18 gauge rated. I remembered that because there is a potential overheating problem, you do not want a wire of thicker gauge further away from your source (the transformer) than a thinner gauge wire next to your source (again, the transformer). I abandoned the solid, 18 gauge wires going out to the Ring VDB 2 and instead connected via wire nuts another run of standed, 20 to 22 gauge wire. - Voila! Everything worked as designed. No smoking or hot resistor. - A word of caution that I can confirm, but which has been mentioned by others: the app on your smart phone may not (make that, probably will not) update for a few hours. So you will not see the Power: Hardwired immediately, only Power: Battery. Your telltale sign that the hardwiring is indeed working is the continuous lighting of the white LEDs on the face of the Ring VDB2. - Hope this helps someone!
