Using latest firmware for home (2.28.0 (att)). And thermostat firmware 11.8 with plug-in version 1.122. From my iPhone app, there is nothing like what is found on page 15 of the user guide (https://support.wyze.com/hc/en-us/articles/4402618339099-Wyze-Thermostat-User-Guide-English-US-). I go to controls and all that is available are State and Mode. There is no Fan section. There is absolutely no way to control the fan. None.
