@Lisa Hello. Could you tell us a bit more about your system and which tado devices you have please? Just to confirm - early start is accessed through smart schedule for your bedroom and then top right 'cog' -should be showing grey - off.
Hi - No you don't want settings or rooms. Just use the opening page of the app and select your bedroom then Smart Schedule then cog in top right corner.
@Lisa Sorry - just re-read your first reply and had missed the fact that you appear not to have any tado radiator thermostats. If that is the case, then your room called 'heating' should be selected to get you to the Smart Schedule.
