Low Voltage Hardwired TransformersWired Door Chime TransformerTri-Volt / Clamp-On or panel mount typeInput: 120VAC - Output: 8VAC-10VA, 16VAC-10VA, 24VAC-20VA
the best way to convert 120VAC to 24VAC is with a transformer
search Amazon for doorbell transformers... here's one for less than $15
Wires are wires. Cat5e just means it's four twisted pairs of 24-26AWG wires. Most commonly terminated for use with network connections but you can do whatever you want. The one problem is 26AWG is pretty tiny. So what I would do is combine two (or four) wires together. One set for hot, one set for neutral. Then get a 24V transformer. Wire the 120V side to your electrical panel and the 24V side to the Cat5e wires and you'll get power at your doorbell for the Nest Aware.
Someone linked to this the other day, so it was in my history. Find where the existing doorbell is and replace it if it can't output the voltage you need.

No, that would be the chime. Transformer looks more like this: https://www.amazon.ca/Heath-Zenith-SL-125-02-Wired-Transformer/dp/B000BQY88I/ref=asc_df_B000BQY88I/?tag=googleshopc0c-20&linkCode=df0&hvadid=293000757354&hvpos=1o2&hvnetw=g&hvrand=1265764340987784692&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9000752&hvtargid=pla-386434971311&psc=1 and would likely be located either in the wall behind this chime, or somewhere closer to the panel.
I ordered this transformer and it works fine with the Ring 2 at 24V 20VA

It's been about 12 hours and has charged the battery 3%.
>So I was going to buy a new transformer. Are you saying I should go with a 24V over a 16V? Is that preferable?
24 V transformers are only needed if there's a long wire-run between the transformer, Hello, & chime. If any of these distances are more than 20 feet you should get the 24V.
Your best option would be one like this: https://www.amazon.com/Heath-Zenith-SL-125-02-Wired-Transformer/dp/B000BQY88I/ref=sr_1_1?ie=UTF8&qid=1537965228&sr=8-1&keywords=Heath+Zenith+SL-125-02+Wired+Door+Chime+Transformer
It supports 8, 16, & 24V for future-proofing.
I just checked the electrical unit which has the transformer.
It's a 16V transformer, 10 VA (not sure what VA is). Transformer Model: CT-380G 122C-A Multi-purpose 16 Volt AC Heath Zenith
If I upgrade to this: https://www.amazon.ca/Heath-Zenith-SL-125-02-Wired-Transformer/dp/B000BQY88I#customerReviews
24VAC-20VA, will that be enough power?
