I have google wifi which works on mesh technology. Everything works fine without the chime pro extender. I do have an extender, but I don't use it as an extender, I use it as a chime. So I'm paying for something but I don't really use the full functionality. Still, I like the chime each times one of my cameras has an alert. When I hear the chime, I check my app. It's less annoying than all of those notifications on my phone. Or if I don't have my phone on my person.
