DEWENWILSPool Pump Timer, Outdoor Wi-Fi Box, Heavy Duty 40A 120-277 VAC 2HP Wireless Controller Timer, Water Heater, Compatible with Smart Phone, Alexa, Google Assistant, UL Listed

I installed this pool pump timer last summer after a different timer failed after only one season. This timer has been rock solid for 1 year next month. The app was a little confusing at first but I figured it out quickly. I can control the pump and make changes to the schedule from anywhere. I will update this review after another season.

***update 8/8/2020***After struggling to get 2 different units working, I purchased a GE unit (https://www.amazon.com/dp/B00YTCZZF0/) and swapped it in place of the Dewinwils unit. No change to the wiring at all. As soon as the GE unit kicked on I was immediately able to connect it to my SmartThings hub, and had instant control over the device. The GE unit is considerably more money, but let me tell you this - it worked right out of the box, no fuss. The Dewinwils unit doesn't look ready for prime time.To be fair, they finally did reach out to me by email, but the entire troubleshooting regimen they prescribed I had already done exhaustively myself. I weighed out the benefits too - even if through exhaustive troubleshooting they were able to make it work, how often would I have to mess with it in the future to keep it running. No thanks guys. Please work on the out-of-the-box experience, so many people in the reviews here complain of having to vigorously troubleshoot to get and keep their units running, that isn't going to fly - especially for a device to enable automation! We want this stuff to work every time!I'm usually very patient when it comes to electrical wiring projects like this, but this one has me ready to give up. I ordered this item to power my pool pump, which is a Hayward 1 horsepower 120 volt pump. By all means this unit checks all the boxes I'm looking for in a pool timer, I just cannot get it to work. The wiring for this thing is simple enough, and I don't think there is anything wrong with my wiring connections. As soon as I apply power to the device, the Wi-Fi light starts flashing and I attempt to connect my cell phone to it to begin setup. As soon as I establish the initial connection the Wi-Fi light goes out, and my phone drops the connection immediately. Afterwards the Wi-Fi light will come on and stay on solid, and then it will begin flashing and then it will go out and it keeps doing this over and over and over again. I cannot maintain a connection to this device for more than a second or two, so I can never complete the setup. The manual power button will work to turn the pump on only when the Wi-Fi light begins flashing. Within seconds the Wi-Fi light turns off, the pump will run for about 5 Seconds and then shuts off. I can turn the pump on with the manual power button anytime the Wi-Fi light is flashing, but when the Wi-Fi light is solid or when the Wi-Fi light is off the manual power button does nothing.I'm frustrated and cannot seem to figure this thing out at all. I emailed support but they haven't responded to me in days. I want this thing to work, but I am losing hope. If I can't figure it out in a day or two I'm putting it back in the box and sending it back.

WiFi controlled unit works perfectly for my 220 volt roof top ice melt system and can be activated/deactivated from within the house or from anywhere with good cellular data or WiFi service! Excellent value for the money.

Replaced an older Intermatic digital timer with this unit because I wanted a little bit of smart ability, such as being able to use Google or Alexa to automatically shut off the pump after an hour if someone turns it on, etc. I haven't got to that part yet but it should be straightforward. The unit was easy to swap in and lit right up when I applied power. The app isn't as slick as it could be but it doesn't really need to be i suppose. It works, there's one button, that's all it takes. Setting up wifi was simple and quick. Note that it only supports 2.4Ghz so if you have a mixed band network you're going to need to separate the bands into different SSIDs or it probably won't join. I used my IoT network which is 2.4 only so it gave me no issues.The terminals seem a little less robust than the old Intermatic timer and the screws are shorter so it can be a bit of a pain to get the thick wires in there especially if there's a line and a jumper, and because the little plastic lids over the terminals don't stay up on their own. You'll need a wife or some tape to keep them out of the way to save you grief. 4 instead of 5 stars for those reasons and because it's a company I've never heard of before 'Dewenwils'. It was super cheap so I figured I'd try it. In a year if I haven't gone back to the old timer I will add the 5th star.

I have to travel for a week during the summer but my pool pump has to run normally. My worst fear is if a pipe bursts or something catastrophic happens to the plumbing. This device will give me peace of mind while I am away. The price makes it a sweet deal.I did not take long to install the unit to replace the current Intermatic T104 electromechanical timer. Unfortunately, the unit I received did not work. I had trouble connecting the device to WiFi and setup the iPhone app. I contacted Dewenwils technical support and Cecilia helped me walk through several steps to troubleshoot. No luck. Cecilia then offered to send me a replacement unit to try again. On the next day, I received the new unit. This time, I only hooked up AC power to the new unit to do my configuration and make sure I do not have the same issues as the first one. Within minutes, I got the new unit connected to my WiFi and got it added to my iPhone app. I am as happy as can be. Many thanks to Cecilia's patient support. Kudos to her.

So far so good been installed for 5 months now working without a glitch. Hook right up to my phone no problem.
