  • Extensive customization/schedules, great implementation
Voltage: 250 Volts
I'm impressed at how much functionality is in this Mumubiz 4-channel Wi-Fi smart switch. Each channel is a 10A SPDT relay (normally-open and normally-closed contacts), for 120-240VAC or 30VDC. For basic functionality you press the buttons on the unit/remote/app and the corresponding relay toggles. In the app you have four switches and their statuses. With Google/Alexa they show up as four separate devices that can be turned on or off, along with a fifth device that turns them all on and off as a unit. The RF remote requires a fairly a small A27 12V battery which isn't included. For security the RF remote is not by default paired to the unit. Inside the unit there are pads for a 5-pin header to wire up external buttons or other controls for the relays (like pressing the button on the front). Fifth line is the common. There are also LEDs for the relay statuses but the case doesn't have holes to see them; easy fix to drill holes if needed. Connection to the app was easy and it works with the popular Tuya/Smart Life apps. There is extensive customization: Interlocks: relays can be put into groups where only one is ever on at the same time; turning another relay on in the group turns the first off BEFORE the new one (I verified that this really is done correctly). Toggle/momentary: the control buttons/5-pin header can either toggle the relay state or just momentarily click the relay only for as long as the button is pressed. Power-on default: all relays off, all relays on (unless interlocks are added), or restore previous state when last on. Each relay can have "inching", where it automatically turns off after a set amount of time, from 1 second to 1 hour, in second precision. You can set up a manual countdown timer for 1 minute to 24 hours for each relay. Each relay supports extensive scheduling. There can be multiple events for each type all at once. Each event is active for a set block of time on particular day(s) of the week. Schedule: turn on or off at specific points in the day Circulate: cycle on and off repeatedly with a set amount of time and set amount of time off for each cycle, e.g. turn a pump on for 15 minutes each hour, for four hours at 5 PM on weekdays. Random: turn on and off randomly (presumably not every often, to act like a person is at home turning lights on and off) Using USB the unit draws very little power, <40mA idle, 330mA with all four relays engaged. CAUTION: the AC power supply doesn't use an isolation transformer; it's just a buck converter running live (specifically, the ground of the low-voltage electronics inside is connected to the - output leg of the bridge rectifier that the AC goes into). The USB ground won't be safe to connect with, nor the 5-pin header inside. Note the the relay contacts are always isolated from everything so there is no issue with core functionality. ... show more

  • A little difficult with Tuya
Voltage: 250 Volts
This is a reasonably good switch once it's set up, but the setup experience was less than stellar. Although the device was immediately detected by the Tuya Smart app, the app would hang while trying to bring up the four virtual buttons and the settings necessary to pair it with the remote control. It seems like the app has to download who-knows-what from the Internet before it will work, which can take a long time (minutes to hours in my case). The remote uses a small 12V battery that wasn't included. I happened to have a 27A-size battery that fits and works with the remote, but it's a fairly unusual battery to keep on hand. Now that it's been set up, the relays work well and can be switched reliably using the physical buttons on the device, the app, and the remote control. I think the product would be a lot better if they made Tuya optional and provided enough information to set it up independently and control it with other software. ... show more

  • Dynamite comes in small packages
Voltage: 250 Volts
If you've used any IoT devices - smart switches or otherwise - and you need to control several circuits with great ease and flexibility, then this is the device you want to keep on hand. It's more than just a switch bank! There are 4 independent switches of course, but rather than the customary Normally Open contacts present on many other devices of this type, the Common, Normally open and Normally Closed contacts are right there - with screw down terminal blocks to attach your wiring. It's nothing different than having 4 remotely controlled SPDT switches at your command. This device may be powered by mains voltage (80~250VAC) or by the onboard Mini USB plug. I chose the latter. A really clean, good looking PCB with fairly heavy traces on the relay contacts. As you can see from the photos, the relay contacts are rated for 10A maximum current. So far things are looking great... Power this device up and load the SmartLife (Tuya) APP and you're ready to pair & name your device on the Wifi network of your choice. This device, like most other IoT devices, uses 2.4 Ghz Wifi only so log onto your 2.4 Ghz network to set this up and it only takes a few seconds of your time. I'm really pleased with the fact that the manufacturer did not obscure any of the components or their markings, this is a very easy to device to hack as you see fit. If you're wanting to use RF to control the 4 relays, there is an included (see photo) small remote control that you could possibly hand on your keychain. It's rather fragile though - maybe better to keep in your desk drawer in in your pocket. The RF remote uses a standard 27A type 12 volt battery. Although I did test my RF remote and it did in fact work just fine at close range, this will not be my means of controlling this switch array - at least you do have that choice though! It may be handy for the right application. My only complaint, however minor, is that the LEDs that show the state of each relay are obscured by the case (see photo) I plan on drilling out a hole over each and inserting a piece of glue stick to conduct the light from the LED so that I can actually view the state of the relay with the cover on. It's an effective method and I've used it before - however primitive it may seem. Mounting options are wide open as well. As you can see, there is a DIN rail mount incorporated into the rear of the case which is very nice to compliment a box full of DIN rail mounted terminal block that a lot of folks use. One could simply mount this device with double sided tape or hook & loop fasteners with equal success. This device consumes very little power! In standby, it consumes 100mA and with all four relays engaged it pulls a scant 350mA. This relative efficiency make this device a great candidate for solar powered/solar charged devices! With almost endless uses, ease of implementation and it's low power requirements - you've got the trifecta! Time to get down to the grit of your next IoT project - they've done almost all of the work for you. I've got nothing but good to say about this thing. I'll be requiring several more of these for lighting projects/signage as well as quite a few motor controls that simply must go wireless...Time to have some fun! Two big thumbs up to the folks at Mumubiz. Very well done! ... show more

  • Used to control all the garage door openers in our shed
Voltage: 250 Volts
Very happy with this. it has allowed me to have all three openers on one controller. It was simple to add to my home automation system allowing for easy integration into Alexa and the rest of my home. The CB3S chip is exposed and easy to flash if you need to change away from the Tuya cloud platform. having an 85V - 250V AC input eliminates the need for a power adapter. overall for $20, this is a great value for a live voltage powered relay board. ... show more

  • Works well with Alexa.
Voltage: 250 Volts
If you're looking for a way to control low-voltage devices or to voice-enable some other on/off switch, this device will do it. You can power it using hardwired AC or via a 5VCD USB plug. It also came with a four-button wireless keyfob that can turn each channel on/off. Handy little gadget if you have a use for it. ... show more
