In the hubitat documentation under network set up it says…
Advanced Network Options
Some advanced network settings are currently not available via the UI but can be changed via HTTP endpoints if needed.
Modifying these settings is not recommended for most users. Use caution, and only modify settings that you understand and know are necessary on your network.
- Change subnet mask (and set static IP, gateway, and DNS): Static IP Address and DHCP Support for non /24 Subnets - #13 by gopher.ny
- Change NTP server: Issues in 2.2.4 Latest - #7 by gopher.ny
Other Options
- Ethernet speed: Default setting is Auto negotiated (default) and recommended for most users. Selecting Fixed 100 Mbps is recommended only for users experiencing problems with the default setting (in particular, certain models of network switches have problems with auto-negotiation, with the most common symptom being slow loading of pages via the web interface).
- Auto reconnect: Default is Disabled. If enabled, the hub will ping router at the specified interval and attempt to reconnect if no response. Use if hub drops off LAN while using Ethernet. This setting works with DHCP wired connections only (not static IP or Wi-Fi configuration).
