TOPGREENER Digital Astronomic Timer Switch, 7-Day Programmable Sunrise Sunset Timer for Lights, Fans, & Motors, Single-Pole or 3-Way, Neutral Wire Required, UL Listed, TGT01-HN-W, White

Great Timer, nice looking and functional
Love the timer. It is very functional. The features are good and easy to use once programmed. I have been using 2 of these timers for several weeks now. Programming was fairly easy but I am pretty familiar with these types of electronics. I like the blue light backlight. It only comes on when you push the button which is good to sit is not lighting a dark room at night. There were also some complaints about this timer not fitting a regular wall plate. I am using the leviton decora style wall plates. The timer fits those perfectly. You DO need a nuetral wire to be able to use this timer which is the case with most of these type of timers. I hope the rechargable battery stays good for more than 7-8 years. I don’t like changing things often after I put them in because I am a very busy person. I don’t have time to deal with swapping things out. I don’t see that the batteries are replaceable so I will just plan to replace the entire timer when that happens. I have 2 of them side by side so I will likely need to replace both if they don’t make the same style when the batteries go bad.Directions need some work. It is not clear how exactly how to set the dawn to dusk feature. I doesn’t really tell you that the dawn to dusk button is the one with the little moon and sun images on it. You need to press program, then press set , then press the dawn to dusk button for moon to set the on setting. The instructions fail to tell you to press the set button, then the dawn to dusk button. I did call customer support before I bought this timer to ask ask about using it with a dimmer. They said you can’t use it with a dimmer. They did not have someone available to answer my questions but did call back within several hours. Also, I found out that you can use it on a 3 way set-up but I think you MAY need to make sure it in the right spot within the wiring run. If you wiring 3 way and it is not working, call customer service to ask about that.That all being said the timer is still great and I would buy it again.

Easy programming, Great, with lots of features.
This is an excellent, reasonably priced, full featured timer with easy to program 8 on and 8 off settings. It has latitude (North-central-south zones) and dawn/dusk compensation for the time of year, including Puerto Rico and Mexico. Canada is not included in my model. I especially like the fact that it uses standard clamping screws for wire attachment instead of 12 GA stranded leads which add to the wire clutter in the box and are hard to accommodate with other solid wires in the wire nut. When changing to this timer I was able to eliminate 8 wire nuts and all the pigtail leads, meaning they went into the box more easily. Comes with white, beige (antique white), and brown cover plates. This is a Decora wall plate device. Comes with a single gang durable white Decora wall plate with screws. Antique and brown wall plates are not included. UL Rated.Hookup for single pole use is easy. Note that a neutral (white) wire IS needed. 3-way installation is relatively straightforward. However… It does not use a standard 3-way configuration and so is not a direct replacement and must have power available. Wiring changes are needed at both ends of 3-way circuits. The 4-way switches in between (if a 4-way circuit) do not need to be rewired. You have to be aware of this and may have to figure out the circuit diagram, if you do not have the configurations in your switch boxes shown in the instructions, which I didn’t.The only fault I can find is that the back light turns off after a short time and the display is hard to read when off. However, while programming or when you turn it on or off manually, the back light comes on and the display is fine.Durability and reliability have not been tested, but I did install two units and both are working perfectly. I will report back in a couple of months if anything changes. Recommended for those who know electrical wiring. Otherwise have a qualified electrician install it.

I have had these Astronomical Timers operating for several months now and I am very pleased with their performance. Our house now looks great in the evening at dusk with the outside lights on. I had zero problems setting them up to perform as desired after reading some earlier reviews and setting them for the correct North zone (and not our time zone as I originally thought). My only issue was struggling to align them correctly as mine are in a four switch gang box. Patience getting that right is an asset that was tested to the extreme in my case but eventually accomplished without any modification to the new plate cover after I broke the original one. I can recommend these switches as they seem to be “Set it and Forget it”. Whereas I have couple others that require periodical adjustments though out the year that is annoying.

This timer stopped functioning after a little over a year. Too bad TOPGREENER warranty is 1 year and they will not replace the unit. You would think an electrical product like this would be designed to last.It worked fine a year, was fairly straightforward to setup & install, and turned the exterior lights on/off at dusk/dawn. Then it stopped working.1) The timer will not pass power onto the load side, even when you manually turn it on. Tested with power meter.2) The timer won’t hold date/time settings. I set the current date/time and came back to check the following day and says it’s 2017 again and the time is incorrect.Had to remove and throw it out. I find this very frustrating.
