I can now recommend another great router option for the Aqara devices. The CC2531 zigbee sniffer flashed with the free firmware at this site
are excellent. They interoperate perfectly with both IKEA and Xiaomi devices. This can be the lowest cost router option as the CC2531 is available on both EBay and AliExpress for $5 or less in quantity. However you will need to purchase a CC2531 Sniffer Protocol Analyzer USB Interface Dongle +Zigbee Downloader Cable. This may be about $15. With this cable you can flash custom firmware from the site listed at the beginning of the post. More information can be found on the site
The Hubitat seems to prefer routing through the CC2531 over the IKEA devices. I have 65 Aqara Temperature sensors 16 IKEA Routers and 24 CC2531
