I'm not sure why you have multiple networks. In most residential setups I don't find that's it's worth the complexity. In commercial settings where you need to create isolation between teams for security or other reasons, sure. But most homeowners are like you in that they expect everything on their home network to talk to everything else on their home network. No need for multiple VPNs. I also find that for most places an 8 bit subnet (192.x.y.z) is not enough devices anymore. If your installer is using multiple subnets because you're running out of IP addresses, they should just use one big 10.x network. I am now using 16-bit subnets everywhere (10.x prefixes, 64K = 65536 IP addresses). If a person has multiple homes, I use a different 10.x network for each home and VPN them together. (e.g. 10.1.0.0, 10.2.0.0, 10.3.0.0, etc.) But each home is one subnet with a max of 65536 IP addresses. I will say that the one exception to the multiple VPN rule is for a guest WiFi network. If the homeowner wants a guest WiFi network, that sits on it's own VPN for security. Bottom line, I'd tell your installer to put everything on one subnet and stop making things so complex.
