30A Hight Power WiFi Wireless Smart Switch, DIY Module for Smart Home Automation, ewelink APP Remote Control, Timer, Compatible with Alexa & Google Home

This little device is awesome. I set up 4 high bay led lights to work off of this in my pole barn and it works awesome. I love how I can control it with my phone wherever I am and also has scheduling ability.

We installed this for a costumer that was tired of walking to the lake every time he needed to turn on his water pump. Works well and saves him time and steps!

This product is dangerously underbuilt. The internal electrical wiring is too small for the load it claims to handle. Even when used under normal, advertised conditions, it quickly overheats. After a short time, it stopped working completely.This is not just poor design — it’s potentially a fire hazard. If you’re looking for something safe and reliable, I strongly recommend avoiding this product.

I got it to work by finding eWeLink app. It was super easy to set up and it works with Alexa, seamlessly. The reason for 4 stars instead of 5 is because it came with a manual completely in Chinese. Not a hint of English. C'mon guys, you're selling to one of the largest markets on the planet, so you can't take an hour to add an English manual? UGH!

Let me start with --- The effort was worth it $$.The easy part... Adding this device to the power feed at the water heater. My electrician friend had it installed in about 10 min.The interesting not so easy part -- Connection to the network and programming.- I struggled to connect to the network - This only connects to 2.4G, and I could not find it on my network.- I created a 2.4G and 5G mode and was able to find it and connected.- Programming took me a bit of time, but not too bad. I now have a weekday and weekend schedule and easily turn off the “On” part of the schedule to leave it off while on trips. Turn the schedule back on before I get home, remotely! :-)I have not had one issue with this smart switch since I got it running. My biggest upfront issue was the 2.4G connection. If you already have a visible 2.4G/5G network, your setup will be easier. You need to have a 2.4G Wi-Fi signal where this switch will be installed.

I installed this on my furnace power in place of the toggle switch and connected to wifi so I could cut the power power to furnace if I had indication of any malfunction (based on my smart thermostat data) while away. Problem that prompted me to do this was a sticking inducer relay on control board causing the inducer to run after heat signal was removed, preventing furnace from firing up the next time heat was called for. Since this switch relay coil is always energized for my need to provide power to the furnace, the switch is slightly warm, but not of any concern. Time will tell if this reduces life of this device. As an aside, I fixed my control board problem by swapping the ignitor relay (resistive load) and the inducer relay (a motor-inductive load) and have not had any sticking issues for the past month of frequent furnace operation.
