Hive Landlord Control to return to Schedule at 0 minutes past the hour. If your tenants change the temperature up and down it will return to your schedule. Alternatively, a friendlier way to give your tenants the benefit of the doubt is set up 2 for every 30 minutes or 1 for every hour. For multiple houses set up an individual ifttt login to match your Hive email addresses. Beware: savvy tenants can change the schedule from the stat - so check online periodically to check it is your schedule.
