I found that researching wasn’t as straight forward as I would have liked. Good info on the Amazon site, even more on Eufy.com, but to me not well organized. HomeBase 3 S380 is the newer base, but you need to look at the compatibility chart. I started with HomeBase 2 (was on sale) but have decided to upgrade and the newer items need HB3. Fortunately when I bought I took advantage of an upgrade offer to HB3. There are some price reductions that will be available in a couple days via Prime Days.
I also noted the bundles are not always cheaper than bundling your own.
