desertcart.com : Techbee 1 s to 999 h Short/Long On-Off Interval Repeat Cycle Timer Plug Outlet with Countdown and Light Sensor, Waterproof for Outdoor (15A 1HP) : Tools & Home Improvement

Review: Precise seconds interval suited my needs - Works great. It was easy to program and confirm settings. Seems durable and high quality. It's been reliably switching off/on a grow light that is connected to another separate standard weekly timer. I have this Techbee repeat interval cycle timer set to remain on all day and quickly switch off/on for just two seconds shortly after my existing weekly timer switches on a plant grow light each day. That grow light has three different color modes designed to affect growth. My plant light modes can only be changed by depressing a foot switch on/off/on/off/on/off in sequence. I'm using this cycle timer to simulate a manual off/on toggle foot switch that switches through the plant light's three color modes. I now have my plant light automatically switch on, and once on, this repeat timer will automatically switch it off/on for two seconds so it advances to the next light mode in the off/on toggle sequence. With a short off/on 2 second setting, I can now manage my plant light automatically. It's very flexible and has precise programmable timing. I also like that it's water resistant as it sits right below my plant.
Review: Great value - Works great Easy to program

## Questions & Answers

**Q: Why is the screen of the timer I received blank and unable to be set up?**
A: This timer requires being plugged in for use and setup. It can be set up normally once it is powered on.

**Q: Can I set the current time on this timer? And does it do daylight saving time?**
A: No, you can’t set the current time or adjust for daylight saving time with this timer. It’s a cycle timer that works on short or long intervals. If you do need to set the current time, you can check out another model we have—T319.

**Q: Does this timer retain programmed settings during a power outage?**
A: Yes, even in the event of a power outage, the timer will retain its programmed settings. Please note that once power is restored, the timer will resume the program based on the state just before the outage.

**Q: Is this timer waterproof?**
A: Yes, it’s waterproof in structure and material. However, please make sure the nuts are snugly tightened onto the timer’s bolts for 100% waterproofing. For outdoor use, mount the timer vertically and position it at least 2 feet above the ground.

**Q: Why isn’t it working as programmed?**
A: The light sensor has a 12-minute delay to prevent interference from light sources like flashlights or car headlights. Also, if you use the light-sensing function indoors, please make sure to keep it away from light interference.

### ⭐⭐⭐⭐⭐ Great value
*by B***N on January 5, 2026*

Works great Easy to program

### ⭐⭐⭐⭐⭐ Perfect for hydroponics
*by K***S on October 14, 2025*

Overall, this is a useful little gadget- in my use case, I’m using it to cycle a small water pump for my hydroponics. You can set any increment of time (1 second to 999 hours) On and off (can be different lengths of time). For the price point, quality is as expected and it’s stood up to some harsh conditions over the years, I can’t tell the one I bought last month apart from the one I bought 2 years ago. The only con with these units is that randomly, if the unit loses power (say, if you have it on a switch controlled circuit), it will sometimes reset and loose its programming when the power is restored, but it generally has good power-loss-memory.
