Updated WiFi Wireless Smart Switch Inching Self-locking Relay Module,Set Inching Time from 0.5 second to 1 Hour,be applied to access control,DIY WIFI Garage Door Opener (Smart life app 2CH)

Make it easy to control your Hayward VS pool pump speeds via Alexa. Perfectly suited for doing that. Note the toggle switch in the lower right corner of the junction box: it allows me soft stop the pump for maintenance. I don't trust software control for everything thus there is also a relay control (not shown) for totally powering down the pump system.

Bought this for a project I created for a video doorbell that didn't support my original/standard chime out of the box. It does require some DIY tinkering, but afterwards it works great for connecting to my original chime! For the DIYers out there this relay device (at the time of writing) does come with a PSF-B01 wifi module, which makes it compatible with Tasmota/ESPHome. Also just in case anyone was wondering, mine did come in a nice little plastic housing case, as well as a 4-button keychain remote (battery not included). Anyways, this has been well worth the purchase price, and very deserving of a positive review!

Fast delivery. Item is as described.

100+++

This device is designed for energizing circuits either in short bursts or longer ones, to be controlled by the internet.I was using to control a gate opener via internet. This device is really quite well done, but it needs a better explanatory guide. I've set up other automation devices and all of them are about equally challenging. Indeed if you have done one or two you will follow your instincts to make this one work. Even with a false start or two it only took about fifteen minutes to have it working. (Soldering connection on the other end were not the fault of this device, but that was the challenge).I will say that the app that you use with this device is good. I am actually quite pleased with its features, including variable length inching (try longer inching if you don't first succeed), and the app is pretty clear and has widgets, and even Siri control that works well. So I would give the app an A+++. It also has a feature that allows you to specify what state the device should find after a power outage. It'll also send you a note if it has gone offline (like you lose internet).

The media could not be loaded.  I haven't installed it yet but I think it's going work great to open and close my chicken coop door. It found my wireless network right away and I can it with a phone app or with Google voice commands.

Great product. Easy to install and easy to use.

I bought this because I wanted to allow Alexa to open and close a gate. I saw a video where someone did this using a gate remote control. I did the same with an old remote which had the solder and pins on the underside, the newer remotes that I had don't have this and touching the two solders on the top didn't short the remote to open the gate so not sure how those new ones work. I soldered on bell wire to the underside of the remote control button for the two of four that created a short that opened the gate, then connected those to the wifi rf bridge.Before that though I had a hard time connecting the bridge to the network - it turns out that although I thought it was close enough, the distance between the router and bridge was too far. When I moved it closer the two connected. However, there is a light near the relay that will come on when you hold down the button close to the dc input (manual pair) which isn't even shown in the leaflet. I can't remember now if when this is on if it will or won't pair because of the amount of time and tries it took me to pair.Because I got this installed before attaching the bell wires to the remote (I did that another day when I found the old remote) I couldn't find out how to set it to inching at first. You have to click on the plug (Ewelink saw this as a plug for me) and then click on the three dots in the top right then select setting from the drop down menu then scroll down to inching and set it to on. The default setting is 0.5s which I left it at but it took awhile for it to decide to connect and change the setting for inching on! The gate in the meanwhile was opening and stopping until I got the inching switched on.Alexa sees this as a plug so to open the gate I have to tell it to turn the name I gave it on, then off, to open, then to close the gate tell it to turn NAME on then off otherwise it will be stuck in ON and the gate will remain in whatever state it was and will not respond to turn NAME on to open or shut, this is the one drawback. It is nice to have the ability to open and shut the gate from anywhere a speaker is rather than have to use a gate opener in line of sight of the gate or the wall switch to open or shut the gate, so much more convenient.

Excelente producto, lo use para automatizar la puerta eléctrica de mi casa, configurado por comando de voz con Alexa. Fácil de configurar y conectar

We use this to perform some home automation tasks, it took me a while to find out how to set the inching on the relays, you find the settings under the timer option on the Tuya app.They work with low wifi signal, even though it reports in the tuya app, I can ignore it and the rssi is -76 which is fine.

Fácil configuración

Equipamento perfeito para utilizar num controlo automático de rega juntamente com uma fonte de alimentação para as torneiras.

I bought this to install inside my garage door opener specifically because this can not just turn on or off like a normal switch, but because you can specify the duration - meaning you can send a momentary 'push' of a button. And it works perfectly. It was simple to install, and easy to configure.The only catch and caveat is that it really struggled to connect to my wifi to start with because my router (like most routers nowadays) is dual band and 2.4ghz plus 5ghz. This device simply would not connect and I was really struggling. I ended up having to disable the 5ghz band on my router just to set this device up, and then re-enabling the 5ghz band once it was setup.Once done, the device connects every time to 2.4ghz but it was a bit of a faff to have to reconfigure my main house router just to get a device to connect in the first place.Going forward, if the makers could supply this in 5ghz also it would solve this niggly issue.Overall, I'm happy with the device and it works perfectly for what I got it - just be aware that setup might be tricky if you have dual band wifi :)
