DEWENWILS Pool Pump Timer, Outdoor Smart WiFi Box, Heavy Duty 40A 240VAC 3HP Wireless Controller Timer for Pool, Water Heater, Compatible with Smart Phone, Alexa, Google Assistant, ETL Listed

Excellent product, easy to program, easy set up, app works great to control it from anywhere you have the internet. Timer works great. I wish I had one years ago.

Works as advertised to control an electric water heater. I tried this as the water heater is inconvenient to get to and remote control seemed like a great option. So far the scheduling has worked perfectly. Connecting to wifi was a bit confusing as it didn't appear to be added on the app, but attempting to add it again gave an error. When I backed out a screen it was indeed already there. Connected easily to Alexa and it can turn it off and on without having to open the app. I had a challenge physically installing it as I used 3/4" BX and connectors, and had difficulty finding the grounding lug connectors it says are required. 1/2" grounding connectors I found at my local hardware store but I had to order the 3/4" ones - go figure. They were a tight fit-recommend going with 1/2" if you can.

I bought this timer to automate and control my outdoor sprinkler pump. I have two zones that I wanted to water three times a week. I needed a total of 12 scheduled timer events. Six to turn the sprinkler pump on and six to turn the sprinkler pump off. The app on my phone made setting all these events very easy. I had previously been using an Intermatic analog timer, and I never could tell which day the pointer was pointing to or if it was going to be turning on or off. When the clock function stopped working on the Intermatic, I decided rather than replacing the time clock in the unit I would just replace the entire unit. I am so glad I did. It’s such a pleasure to not have to go out to my pump every time I want to turn my sprinklers on or off manually. Also, I connected it to my Alexa app and that works seamlessly as well. Installation was straightforward. The Wi-Fi hook up went very well and so far I’m very pleased with my purchase.

Overall, the system works. I used the switch/timer for my hot water heater. I did have to upgrade my wifi extender to better cover the garage where the switch is located but this was no fault of the switch/timer. My only complaint is that if the power is interrupted, the switch is in the off state when the power returns. (The load is off after the power is restored.) This can be a real issue for people with load controllers on their home (energy management systems) or areas with intermittent power failures. (If you don't manually turn on your water heater after loss of power/restoration, you will have no heated water when the power returns.) I wrote the customer service people at DEWENWILS. They answered in just a few hours (good job) with a few line response saying there was no way to have the system come up in the "load on" state. They suggested that I should put in a number of "timer on" events to eventually turn the hot water heater back on after a power failure. However, I have found a way to force the switch to turn the load on after a power failure and power restoration. The trick is to use the "circulate" mode to turn the switch back on. Let me give you an example. I want my water heater to be off after 9:30 pm. I then want the water heater to turn back on at 4:30 am and then to stay on until 9:29 pm. I do this by setting an off event in the "schedule" mode at 9:30 pm (as expected). Then I turn the water heater on using the "circulate" mode with a cycle time of "4:30am on and 9:29pm off. The start duration is 16h 58m and the end duration is 0h 1m. This means that the system can't be off for longer then one minute. Once the circulate cycle starts, the hot water heater will always turn back on after no more then a minute, once power is restored! (I have tested this multiple time using the circuit breaker to cut power and then turn the power back on.) Quite honestly, after I realized how will this worked, I wondered why the customer support team at DEWENWILS didn't suggest it. (Maybe it was just too easy to send back a quick note to the customer and be done?) I gave them four stars because they should either tell people about this issue or suggest a solution.

Great product. It connected very easy to the wifi. The app is very simple and easy today use. As an electrician I recommend this product.

Easy to setup and program using an iPhone.

1-2-25 Could not get the WiFi to setup no matter the steps I took and per the instructions. O yes the instructions, per their support, they really don't pertain to this specific unit. You will never get the quick blue light flashing when you attempt to connect. ( knowing that is helpful you think) As an IT person, this just chaps my hide. Yes, I know how to turn off the 5hz antenna, yes I know how to setup a router. No, the CD player is not made to hold my coffee cup. The other suggestion from support was for me to make a video and send it to them. SUGGESTION: why don't you as a company make one and send to me how this unit ( this specific unit) is connected to the WiFi. Post it on YouTube for the rest of the world to see. O. update your instructions to reflect the actual behavior of this unit. Humm

Easy install, good quality, has a safety panel (not all products have it). Works with Amazon Alexa. The app (at least on iPhone) is deficient: on the main screen it shows the product, but it does not show if it is on or off. If you plan on operating it using Alexa, its not an issue, but rather annoying otherwise.

Good construction and finish are a very rugged box that will stand outside. In my case it will still be located in a garage area but rugging is welcome given door can be open; it is not tempered. Beside that, the setup and operation are straight forward and when used with good electrical connection then operation are also safer. The WIFI function gives a good range and therefore flexibility as to where it can be installed. Then you can control at distance and do programming via the application. Setup start and stop time, cycling and other basic condition while linked to something like Google Home. EDIT: The device is also detected by Tuya, so you can use this app instead and add to Home Assistant via integration. I switched to this for even more control.

Wish I could get it earlier. Totally free myself from taking care the pool. I am able to take a small trip without worries about my pool.
