Yeah mate but not just a timer. The TH16 can use information (temps and humidity) to switch appliances as necessary depends what you want it to do.
They also have a feature called “scenes” which allow you to use the TH16 to switch other channels on different sonoffs. Basically you set parameters and the sonoffs keep them for you.
You can have schedules for lighting etc. You can also set loop timers for flood and drain. The possibilities are pretty broad really.
