Help needed with hardwiring Ring 2 and Honeywell DW915s
Hi there I am looking for help. I have a Ring 2, a Honeywell DW915s doorbell and a 12v transformer which I cannot get to work. Firstly, if I hardwire the Ring 2 to the transformer, the Ring 2 Hardwire LED (white) illuminates. All good so far. Secondly, if I hardwire the Honeywell DW915s to the transformer the Honeywell doorbell works (without batteries!). Still going strong! If I directly contact the 2 wires that should connect to the Ring 2, the Honeywell doorbell activates. Perfect! However, if I connect the two wires to the Ring 2, the white LEDs do not illuminate and the Honeywell DW915s does not chime. The Ring 2 rings as per normal, however, it does not activate the Honeywell doorbell and the battery is not charging. Can anyone here help? The Ring support team have not been able to help me. What I have tried: - some forums state you must have batteries in the Honeywell. I have tried this, does not work - some forums state you don't require the diode. I have tried this, does not work - some advise to swap the siode around. I have tried this, does not work - some advise to increase power to 16v. I have tried this, does not work (8v + 24v connections) - I have increased the gauge of the wiring - does not work - I have manually wired each component on the lounge room floor - does not work - I have replaced the Ring 2. I have upgraded the transformer from 8v to 24v. I have purchased the Honywell DW915s - does not work I have not tried 24v power as the Honeywell states to 16v only. I have attached photos of my wiring. Any help would be appreciated. Thank you in advance! David

Really appreciate all the advice given above, but none of the solutions worked for me with a 2nd Gen Ring doorbell and a Honeywell DW915S. I ended up getting a simple 12V AC electromechanical relay, and then adjusted the Ring using the app to ring a mechanical chime. Works extremely reliably, and I can power both the Ring and the Honeywell off the same 16v AC transformer. Hope this helps someone, as it's much better than relying on the Chime that Ring gave me (which needs an internet connection to function, not just WiFi) and [costs £10.](https://www.amazon.co.uk/gp/product/B07JNFQ2PJ/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1)

AI would be very interested to know how you did it. unfortunately I can't find your wiring diagram or pictures? How did you do the wiring?

Hi all, I would like to connect the Ring 3 to the Honeywell DW915S chime. Could someone verify if it can be connected as per below wiring diagram I made?  Thanks in advance!

I have the same problem and would be happy if someone can send me a working wiring diagram or pictures of how it can work. I would be very grateful!

Attached is a wiring picture of Ring Doorbell 3 Plus attached to Honeywell SW915S wired Doorbell. That should work also with Ring 2. I recommend using a 25 Ohm / 50W resistor when the doorbell is AC powered, that would protect the transformer in a case of wires shortcut at the doorbell. No battery required for the Honeywell SW915S as it is AC powered.
