Google Wifi with opnsense for site to site VPN

[MrRedPants]

I have two homes. One has unify gateway. Other has Google wifi with mesh (3 pucks).

I want to have a site to site VPN between two homes. Google wifi doesn't do this natively. 

I'd like to put a router (opnsense) in the setup for the site to site VPN. I've read about bridge mode for Google wifi, but not sure how this looks in the setup. 

ISP modem --> wan opnsense, lan opnsense --> wan of Google wifi in bridge mode? Or leave not in bridge and just have it act as primary router. (double NAT I guess). 

Im an intermediate with networking. This one hurts my brain. 

Thanks in advance.

Mesh won't work in bridge mode, so all three pucks must be a) bridged, b) connected by ethernet, and c) controlled by a individual Google Home home (one Google Home home can only have one bridged Google Wifi device in it).

If not in bridge mode, you'll have a firewall between the opnsense router and the devices connected to Google Wifi.

Google Wifi does not have advanced features like route tables and VLAN support. I'd rather get some other network equipment for this. Like Ubiquiti UniFi maybe?

Or a mesh system that supports mesh in bridge mode. I think TP-Link and Netgear supports this.

I think I'm just going to have to stick with a client based VPN for now. The site to site is for convenience and it seems like it's not going to be convenient to set it up :D. I have unify gear at the other house of course. Thanks so much for you taking the time to reply!
