Can I use emojis in the Wi-Fi network name?
FAQ , Thermostats , Troubleshooting Modified: March 19, 2026
As long as the firmware on the Wi-Fi router you're using doesn't restrict you to more basic character set like just A-Z, a-z, and simple keyboard symbols, the sky is really the limit when it comes to whatever emoji or other characters you want to put in there. The Lennox S40 Smart Thermostat will display these emojis in the Wi-Fi options.
Note: The Lennox S40 Smart Thermostat does not support emoji's on its keyboard.
