Review: Made Alexa controlled switch for pellet stove thermostat - I wanted to use Alexa to manage our pellet stove. When we forget to turn down the thermostat, it would come on in the night and roast us out of bed. I tried a smart plug for power but found that if stove was running when Alexa powered it off, it couldn't finish it's cool down cycle. I shopped for an Alexa enabled thermostat, but they are all geared to HVAC systems and require a c wire for power. The pellet stove only has a simple two wire thermostat connection. Then I found this relay switch. I soldered a sacrificed USB power cable on, joining the s and + terminals to the positive wire and the - terminal to the negative wire, then cable tied it to a USB power block. I then split one of the stove's two thermostat wires and connected the ends to the center and left outputs(NO Normally On) and plugged the assembly into an Alexa smart plug. Works like a charm:) Alexa connects the thermostat on request or on schedule, turns off at bed time, and the stove maintains power to complete cool down as needed. Perfect little relay!
Review: Works Great... simple control relay - Before I give my review... I wanted to share some information. I have read a lot of the questions and reviews of this device and it seems there is a great deal of confusion as to what exactly this relay board is and what it is intended for. I've been in electrical engineering / technical trade for over 30 years. This is a very simple relay control board intended to allow you to control a heavy load (110VAC, 12VDC light, Motor, etc...) up to 10Amps.. although I would not actually try driving a full 10A with this board. It is NOT a power supply, it does not generate AC outptut, or DC power. It is simply a controlled switch. I have uploaded a simple circuit diagram that depicts this relay and how it might be hooked up to control a simple 110VAC Light / Lamp from an Arduino output. There are a lot of other examples of how to wire this board out on the internet. Now for my review... I have purchased about 5 of this relays over the past couple of years. I use them with the Wemos D1 Mini control board and I have 1 controlling my custom smart wireless doorbell (doorbell button sends signal to my D1 Mini to close relay and ring doorbell chimes). I also have several of these wired inside my arcade machines to power them on or off via Alexa commands. They have all worked perfectly and I have never experienced any issues with them. They are a great board for the price and I plan to purchase more for some other projects I plan to do for home automation.

## Features

- Microcontroller development board can be used as modules, can be used as appliance control
- 5V - 12 V control signal of the TTL
- Control DC or AC signals can control the 220V AC Load
- There is a normally open and open normally closed contact
- Useful to control a motor, a led strip, or any other module. How to use it: Just connect a digital output of your board to your relay module, and you can control a power-demanding appliance with the digital signal

## Questions & Answers

**Q: max wattage on 120v ac USA ?**
A: There is a tough to find data sheet that does spec this unit at a max of 30vdc. Refer to this link for more info, http://electronics.stackexchange.com/questions/97721/why-ac-points-on-pcb-are-separated-by-a-holeThere are products that are very similar and rated for 120v ac use.

**Q: Does it have optocoupler isolation?**
A: No opto-coupled isolation. There is a small transistor onboard that is driving the relay and as someone else pointed out, the coil has a diode across it to supress the counter EMF of the coil. This relay requires very little to drive it as long as it's wired correctly ("+" to 5-12VDC, "-" to Ground, "s" to your digital output. The output is active high (when your output is high, the relay energizes). The screw terminals (NO = Normally Open, NC = Normally Closed, C = Common).

**Q: How reliable are these? I bought one but it just died on me, the led lit but it wouldn’t switch anymore so I had to throw it away.**
A: I've had two of these in service for over 2 years now with no issues.  They are each separately controlling garage door momentary switches.  They are each in  a circuit with an Arduino activated by bluetooth to start the garage door motor from the momentary switch.  They've worked great for me.

**Q: Does this only work with official Arduinos?**
A: No, it will work with anything that sends out a 5v digital signal (though I also had success with a 3v esp8266, so input tolerances are probably fairly wide )

### ⭐⭐⭐⭐⭐ Works well once you find the datasheet
*by G***N on May 26, 2023*

Currently I use an Wireless Android Auto dongle in my car, and the USB port doesn't shut off by itself. I wanted to be able to use the adjacent 12V power source to control the power signal through the existing cable, so that when the car shut off the power to the dongle would be immediately cut. I originally wired a Y splitter cable to split the power wires off to a different cable, but it didn't work properly. This relay works perfectly for my use-case. For the control signal, I soldered the power wire of a cut USB cable to both the S and + pins (left/middle, tied together), and the ground of the cable to the - pin (right). The USB data wires were not needed. Next, I unsheathed a section of of another USB cable, and cut the power wire, wiring one side to the "NO" (normally open -- left) terminal, and another side to the "common" terminal (middle). I tapped into the USB ground wire and soldered that to the - pin where I had previously connected the ground from the other USB cable. You can search the Internet for "Keyes 5V Relay Module manual" to find some documentation.
