I wanted to add reservations to my IOT devices so I can add hostnames (so they show up in Pihole.. currently I just see a lot of IPs and have to look them up in the router UI). When I try to enable reservations I get warnings saying they won’t work.
This was previously reported here, but the thread was closed without conclusion:
Is this supported?
Yes. Reserved IP addresses are supported for Guest/IoT clients, provided the reserved address belongs to that network’s subnet. The warning is currently a UI validation issue: it checks the address against the Main LAN subnet instead of accounting for Guest/IoT subnets. The reservation itself should still take effect after the client renews its DHCP lease or reconnects.
You can confirm it by reconnecting one IoT device and checking whether it receives the same reserved address. This was also confirmed by GL.iNet staff in a recent thread.

Thanks, this sounds good.
However…. For clients on the main LAN, I can modify their reservations in the Network → LAN section. However, this is not the case for IoT/Guest. Those reservations do not show in the same place on the corresponding section (nor in the LAN) section. This means I cannot edit them and assign hostnames.
Is there a way to do this?
The GL.iNet interface currently does not provide a Guest/IoT reservation list where those entries can be renamed. As a workaround, open Advanced Settings → LuCI → Network → DHCP and DNS → Static Leases, locate or add the lease using the device’s MAC address and an IP within the Guest/IoT subnet, then set its hostname. Avoid creating a duplicate lease for the same device, and reconnect it afterward to renew DHCP.
LuCI is the advanced OpenWrt interface, so please back up the configuration first. If the lease is not visible there, please provide the router model and complete firmware version/build so the correct behavior for that firmware branch can be confirmed.

This does seem to work, however all of the “Reserved IP” toggles in the GL.iNet interface have become unticked when I modified them to add hostnames in LuCI.
That suggests the GL.iNet client page is no longer recognizing the LuCI-edited static-lease entries, even though dnsmasq may still apply them. Please do not re-enable the toggles yet, as that could create duplicate or overwrite the existing leases. Reconnect one IoT client and confirm whether it still receives its reserved address; if so, the unticked toggles are a UI synchronization/display issue rather than lost reservations.
Please provide the exact router model and complete firmware version/build. A support team member needs to confirm whether hostname fields added through LuCI are expected to remain compatible with the GL.iNet reservation controls on that firmware branch.

Yep, it appears to be working as I want as long as I don’t te-toggle them. If I do, then I end up with duplicate rows in the LuCI Static Leases page because it adds another.
