I have a new wifi router. the 5G band's SSID default name has an underscore in the name. is that a problem for the Heatermeter/Pi software? I can't connect at 5G. I am able to connect at 2.4G, which has no special characters.
Of course, Heatermeter doesn't need the speed of the 5Ghz band, but wondering about the special character.
