My followup question relates to whether I needed to change the 10k resistors since my transformer is 20VAC. Is 10k one-size-fits-most, or specifically sized for 16VAC as shown in the 2015 blog post?
Yes
The Xformer voltage will vary quite a lot and this was accounted for.
The 10k should work the same.

A lighted button would not work with my BellMote. I believe it was a 16 or 18v transformer. This was mentioned here on the forum awhile back and was suppose to be investigated and mentioned in the blog.
My conclusion given my limited electronics background is that fixing this and similar circuits to handle the presence of a light is more than I can figure out. I
