Scott Greenwald –
Great product and perfect application!
I purchased this product to integrate into my pool pump to make it so that I can control from my phone. This device was very easy to set up and integrated it into the Smart Life app without any problems. I have it in a plastic waterproof container outside and have no connection issues to my Wi-Fi, even though the router is inside. Once to it. The quality is great and the product can be used for so many different applications. Automating a pool pump was so easy with this. After getting it working with the Smart Life app, I then integrated it into home assistant where I set up my schedule for automation. Couldn’t be happier with this purchase!

Great WiFi relay
Works great, paired to truck WiFi and quickly responds. Using it to disconnect remote Turn On wires for 8 ch amp and subwoofer amp. Also using two channels to trigger DSP presets with a negative contact. Works flawlessly. Will buy more for future projects

Pretty Good Switch but Not a True Latching/Bistable Relay
This is a decent well-built switch and would work well for a lot of applications that don’t require latching. As a 4-gang smart relay it worked perfectly and would be great mounted on a wall for garage doors or a gate. It was a bit large to fit in my Casablanca fan conversion but would have fit tightly.This was the only switch from MHCOZY that can have up to two interlocked pairings. I was looking to remotely reverse my 14′ high Casablanca fan motor, so I needed two interlocked “latching” relays (this one has an extra pair), but this relay isn’t a true latching relay and shouldn’t be sold as such. The relay memory setting could have mitigated this, but the memory function only worked 100% when interlocking was turned off. Even if MHCOZY fixed this to work fully with “latching”, the relay switch still isn’t a true latching or bistable relay since the switch coils need to be charged to maintain their state…*** All the switches toggle back to NC when power is lost! ***The memory feature can flip them back to their previous state once power is turned back on, but this obviously isn’t viable as a forward/reverse fan switch in my application. Instead, I purchased a smaller better-built MHCOZY dual interlocking switch and paired it with an OONO 12-volt relay that I set to 1-second inching (yes, inching works in interlock mode). This works great for motors and worked for my Casablanca Inteli-Touch 3 (IT3) smart conversion. This took a lot of trial and error. I hope this helps someone else!

Works EXACTLY as described and EXACTLY what I need!
I see in the description that Amazon states this is a “Frequently returned item”. I suspect that a lot of the returns are that people don’t really understand the device. For me, it is EXACTLY what I wanted. I need a WiFi switch that I can control my gate operator and garage doors remotely. This is GREAT for that purpose. I connected each of my garage doors to one of the 4 relays. I put the two wires from each to the “COM” and “NO” connections. I then set the control to “INCHING” for each and the inching time to one second. Now when I hit the app for one of the doors, the relay closes for one second then reopens. Just like hitting the button on the garage wall!As far as the review about it not being a “true latching” relay, I easily solved that by supplying power to this controller from the Uninterruptable Power Supply that I already had in the garage. Now it never loses power, so the relay always stays where I want them.

Great product!! Customizable programming is as easy as described for relay function and control!
I liked its overall ease and programabilty of its functions, relay inching capabilities which is why I chose it to make a IOT Remote Starting System and Door Lock and Unlock controls for my CAR!!! Which is now remote start and locks are controlled from anywhere in the world through the push of a button on my phone!! So no more going out in the cold to a frozen vehicle for me the rest of this winter!!@ and the best part is a remote starting system for a 2009 chevy malibu, costs over 500 to purchase and have installed usually and with the help of this product I was able to DIY my own for the grand total of $25 and limitless proximity range capabilites equipping the car with a 4 g Hotspot its always connected and ready to Start remotely from anywhere!!

Good simple wifi controlled relay bank.
I run my drip irrigation with this. Few 12 volt water solenoids, some outdoor cabling, and the standard 1/4” poly tubing. Ended up being a whole lot cheaper than the 4 channel irrigation timer and I can control it from my phone. I’ll have to put it in a weather resistant enclosure of some variety, but it’s currently stuck to the bottom of a solar panel with the $10 charge controller that’s been out there for 3 years now.I have a second one that’s lived in the utility cabinet so I can control the water pump, the water heater, and a dump load that’s been going for quite a while too.Connects to wifi easy, easy to set up timers, and the relays on the board haven’t given up on me yet.

WiFI Yes. Bluetooth NO. Cannot operate indepently without wifi
Wanted to use for a multi function Gate control at a location without internet/wifi. Setup will not go through without wifi connection. NO instructions at all for the Bluetooth. After finding bluetooth instructions online, run into similar issue that cannot add the devise via bluetooth without having wifi/internet connection. Ok so I go through all that at home with such, get it all working, but once move away and no wifi, no operation. The app will see it on bluetooth but not communicate with it. Going through the reviews, it appears most ppl are using on their wifi. But for my application cannot.

I used this to control lighting in conjunction with home assistant. I do not trust this type of equipment to switch 240V so it currently is switching 24V contactors which deal with the mains lighting.Easy to pair to the familiar Tuya app and works great with home assistant. I’m sure you can reflash this if you really want local access but I have found this to be rock solid as it comes.

Conexión vía WiFi a la APP Tuya rápida y sencilla. Lo alimento con un cargador de móvil. Acordaros que este modelo no se puede alimentar directamente a corriente de 230 v. Lo tengo en funcionamiento con 3 fases activas, 2 fases con 2 termostatos que encienden y apagan el quemador de la caldera de gas oil y 1 fase que enciende y apaga la caldera que es de gas oil. Funciona muy bien.

Einsatzzweck:Wir betreiben damit 8 Kontroll-Leuchten, die uns anzeigen, ob in einer Etage Fenster offen sind oder geschlossen.Lieferung und Unboxing:Das Relais wurde sehr schnell geliefert und war recht gut verpackt. Nicht zuviel Verpackungsmaterial, aber sicher eingepackt. Im Lieferumfang ist das Relais, ein kleines Micro-USB-Kabel und eine … naja … Anleitung kann man das schwer nennen. Ohne vergößernde Sehhilfen kann man der Anleitung quasi nichts verwertbares entnehmen, da selbst die Beschriftungen der Illustrationen kaum lesbar sind.Anschluss:Zunächst sollte jeder bedenken, dass man sowas nicht ohne fundierte Kenntnisse anschließen sollte. Alleine die üblichen, sehr engen Schraubanschlüsse lassen keine abstehenden Adern zu. Also immer mit Aderendhülsen arbeiten, starre Litze verwenden oder einzelne Litzen mit dem Lötkolben dünn verzinnen.Dabei immer mit Sorgfalt anschließen und auf den Berührungsschutz achten!Als Stromquelle für das Relais kann man Micro-USB oder ein 12V Netzteil verwenden. Bei mir war es ein kleines 12V DC 15W LED-Netzteil für die üblichen G4 Lampen. Damit läuft das Relais ganz hervorragend. Micro-USB habe ich auch erfolgreich getestet.Das Modul besteht i.d.T. aus vier Relais, die eine Zuleitung entweder auf Abgang 1 oder Abgang 2 schalten.Beschriftet ist das mit:Zuleitung = COM (Common)Abgang 1, offen Kontakt = NO (Normally open)Abgang 2, geschlossener Kontakt = NC (Normally closed)Die Umschaltung zwischen den beiden Schaltzuständen erfolgt dabei durch die APP, einen programmierbaren Timer, oder die Tasten auf dem Relais-Modul. Und das ganze halt MAL VIER!Auf der Rückseite hat dieses schicke Modul übrigens eine Klemme für die üblichen Hutschienen. Vorbildlich!Und da kommen wir auch zu unserer Verdrahtung:Wir haben einen L auf die COM verteilt und dann an NO jeweils eine rote 230V Einbau-LED angeschlossen (mit einer gemeinsamen N-Leiste), sowie an NC jeweils eine blaue 230V AC LED. Das Relais sitzt auf einer Hutschiene in einem Mini-Sicherungskasten und die LEDs haben wir in die Plastikcover für frei Plätze versenkt (6mm Löcher).Beim ersten Test mit den vier Tastern auf dem Modul lief alles sofort perfekt.Einrichtung:Der eingebaute Tuya-Chip ermöglicht eine schnelle und einfache Installation in Smart Life oder Tuya.Und danach geht es los. Alle vier Relais können sofort per App gesteuert werden. Eine Programmierung der Timer für jedes einzelne Relais ist auch möglich. Dazu kommt die Einrichtung von Interlock-Gruppen.Was Interlock-Gruppen sind, ist schnell erklärt. Man kann zwei Relais so einstellen, dass von diesem beiden immer nur eines den Schaltzustand NO und das andere NC hat. Schaltet man jetzt eines um, schaltet sich auch das andere um, da nie beide den gleich Schaltzustand haben können. Als Anwendungen kann ich mir Kreuz- oder Wechselschaltungen vorstellen.Soweit, so gut. 433MHz konnte ich nicht testen, weil mir hierfür die Hardware fehlt. Aber Wifi 2,4GHz geht ad hoc.Das ganze ist so schick und professionell geworden, dass ein Bekannter damit jetzt ein ganzes Kontrollpult aus 8 dieser Module und 64 LEDs realisiert. Damit überwacht er dann den Zustand von 32 Sensoren.Die Möglichkeiten für dieses Modul sind echt toll. Die Zuverlässigkeit und die Verarbeitung sind auch super.Über Smart Life lassen sich übrigens auch ganz andere Automatisierungen damit umsetzen. Auch muss man ja nicht zwangsweise 230V AC auf den Relais anlegen. Die Reaktionszeit geht übrigens auch vollkommen klar für ein Wifi-Relais.Bei uns triggern halt die Fenster-Sensoren die jeweilige Automation. So können wir auf einen Blick sehen, ob irgendwo noch ein Fenster offen ist, wenn wir die Etage verlassen.Fazit:Tolles Relais-Modul, klasse durchdacht, Schaltzeit kurz, Wifi zuverlässig, und soo vielseitig einsetzbar.
