I’m looking to setup a dedicated DHCP Scope for different SSIDs. I’d like to have an SSID for my IoT stuff and clients on another.
do this on your router, assuming it supports such a feature. I do this on my access point with VLANs
unfortunately my asus router is awesome for gaming, but not for networking. 
It only allows for one dhcp scope of 253 addresses and has a limitation of 64 static assignments.
You should get a real router then.
FYI: if it sucks for networking, it’s not an awesome “gaming” router, it’s just an overpriced POS.

Thanks for you reply and “help”
I’m sorry if it offends you, but I tend to “tell it like it is”. I hate the term “gaming router” because it means nothing. The fact they sell them at such a high profit margin pisses me off.

If your router and access points don’t support Vlans, there isn’t much point in assigning multiple ip subnets since they would all be on the same logical network. I also suggest getting a better router.
If your router does support vlans (but not multiple dhcp scopes), you /could/ run a separate, internal dhcp server. But this just seems overly complicated.

My access points do support VLANs. I do understand the stance of these “gaming” routers/access points. Maybe one day I’ll invest in some real gear that I sell my customers. I’m not home enough to train my wife how to troubleshoot things if it stops working. The Asus app just makes that easy.
I know it’s the lazy way, but I’m just separating things in IP right now. When I started using wireless at home, I never imagined I’d ever need to actually use ALL the IP addresses in 192.168.1.x…NOW I need to expand on that. I’ve only just started with hass.io recently.
I’ll refrain being a smart ass until I know people better. I tell it like it is sometimes myself.
Thank you,
What devices do you have so you filled up all 192.168.1.0/24 addresses?
Still not sure this is going to work.
If you use vlans on your WAPs, you need some device to route between them.
If you run multiple ip subnets on a single physical layer, you’ll need some device that supports dual IP assignment on a NIC in order to route both subnets.
If your says router supports it, maybe just reassign your single scope to a class B?
I recently moved my family in a property with three houses. A slew of xboxes, iphones, ipads, TVs, firesticks, Echos, etc. It adds up.
I just changed it to 192.168.x.x/16.
I’ll look into a new router later.
It’s far from perfect but you could disable the Router DHCP server and run a Pi-hole. You will have control of the IP assignments and a bit of control on what the IoTs can do by filtering the DNS queries.
What ‘troubleshooting’ do you do if your router ‘stops working’?
I have a pfSense VM setup at home, and it never ‘stops working’.
Of course I had some issues with it, but after resolving them, they didn’t come back. Uptime of 100+ days (uptime could have been bigger, but had a power failure)
Multiple VLANs, different DHCP scopes with reservation and fully configurable firewall.
But do you really need an different VLAN for your devices? Do you have devices that should be firewalled (eg prevent them from ‘calling home’)?
Isn’t it possible to change the subnet mask on your ASUS router (what model do you have)?
I see you changed it.
