Outdoor WiFi Timer Switch 15A 120V
This SURAIELEC TW01A smart timer installs inside a standard outdoor electrical box to control 120-volt circuits up to 15 amps and 1800 watts. It connects to 2.4 GHz Wi-Fi and is managed through the Tuya Smart Life app for scheduling, countdown, random and astronomical timing modes. The grey enclosure measures 2.8 by 1.8 by 5.5 inches and includes 2.2-foot wiring leads with three mounting holes. Rated for 20 degrees Celsius operation, it carries FCC ID 2AFNL-TYWE3S.
Replaces Mechanical Outdoor Timers
Swap out a manual dial or basic digital timer when you need remote access, weekly repeat schedules or sunrise-sunset automation without rewiring the load circuit. The jump is worthwhile if you want voice-assistant integration, shared family control or an unpredictable occupancy mode for security while away. Existing mechanical timers that lack app control, astronomical adjustment or random cycling are the typical units this device supersedes.
Verify Box Space and Network Before Buying
Confirm the target electrical box has enough internal volume for the 2.8 by 1.8 by 5.5-inch body plus the 2.2-foot pigtail wires. Ensure a 2.4 GHz Wi-Fi signal reaches the mounting location, as 5 GHz networks are not supported. Check that the connected load does not exceed 15 amps or 1800 watts at 120 volts and that local code permits hard-wired timer installation in the chosen enclosure.

Questions about this item
What size electrical box and cable length does the TW01A need?
The timer measures 2.8 in x 1.8 in x 5.5 in and includes 2.2FT cables, so it fits standard outdoor boxes with three mounting holes.
How is the TW01A wired and which app step is often missed?
Hardwire the 120V supply to the 2.2FT leads, then add the device in the Tuya Smart Life app on a 2.4 GHz network — skipping the 2.4 GHz selection is the common error.
What upkeep does the waterproof TW01A require over time?
No battery exists; periodically check the gray flame-retardant housing seals and mounting screws for weather tightness, and verify app schedules after power outages.
