I run my Hydros on a Mixed 2.4/5Ghz network and have never had any problems. I have 2 Netgear Nighthawk RAX120 AX6000 routers running my network. The 2.4 and 5Ghz networks share the same SSID (network name) and password. The main router is connected directly to Google Fiber and is in router mode, while the other router runs off of port 1 of the main router and is in Access-Point mode. Every device in my home can connect to this network without issues; this includes devices from Sony, Samsung, LG, HP, ASUS, InkBird, Govee, CoralVue/Hydros, Nest, Eufy, Aladdin Garage Door, and several other off-brands. I think the key to getting this to work is choosing a router that supports "Smart Connect" (this is Netgears name for the feature, but the feature itself is not unique to Netgear), which puts the router in charge of selecting, setting, and maintaining which devices connect to which signal (2.4 or 5) for the network.
