I've added a ToH view for switches - https://openwrt.org/toh/views/switches
...however quite a few switches which are now supported are missing device pages - including some of the best bargains such as most of the HP / HPE 1920 series. I've tackled one, and done a bit of clean-up on others. This page is a good source for missing models: https://svanheule.net/switches/start
An easy fix to do on many switches is to update their Ethernet port info - the ToH added quite a few new items recently (e.g. 2.5, 5 and 10 Gbps copper Ethernet ports, and SFP/SFP+ cages). Again I've done a couple.
On some newer switches the 10 Gbps ports also support 2.5 and 5 Gbps links (e.g. Zyxel XGS1250-12) - the only way to add this info currently is to add a note, but if this applies to a particular switch, please do-so!
