Make Any Device Smart With the Aqara Dual Relay Module T2 

What device will you make smart with the Aqara T2? amzn.to/3ROWt9j

Oh yes!! Thanks now I know this device support pulse mode. This is what I’m looking for.

I have the same garage door setup as you do with sensors. I soldered two wires on the board where the switch connects. You can then open/close the garage door by shorting those two wires or use a relay such as Aqara.

12:44 Mom: "Son, can you fix that railing in the garage I've been asking to fix for months while your back there?" Son: "No, but I can automate your garage door. How does that sound?" Mom:"Whatever, you little nerd."

this pole direction issue is why I swapped to button or tap switches, so that a push is either off or on. Although I realize this is a preference, it is because in the dark I find it frustrating if the pole is opposite of the way I expect. US switches are down for expected OFF and up for expected ON (I realize that it can be different in different countries). As a matter of practicality, I far prefer the use of either voice or smartphone control over stationary, classic pole switches (while realizing that the physical switch is of course necessary when the network is offline or unavailable). Expanding the interoperability of any manual switch just feels like a natural next step, not just for home automation, but general control

Hi Brett, what DC power adapter do I need to get to power for a garage door? Little confused which one to get. Any help would be much appreciated.

Hi Brett. Thanks for the very informative info. Can you tell me if I can connect the relay to a siren, so that I can use it with a panic button?

Great video! Thank you! The T2 looks impressive, I’m going to use to open and close garage door as an alternative to MYq since they locked down 3rd party access. I used to have an automation set up the would turn on over head light when the MYq sensed the garage door was open. Do you think the T2 can mange that along with opening and closing the garage door? Thank you!

Great stuff. Does it recognise triggering scenes on let's say double click on the button switch?

Thanks for shaing , its really helpful. I want to use fingerprint to open the garage . Are there any homekit products can do that?

That relay is BIG. Good luck cramming it and the switches back into the box.

Around 15:46 where are you are making a traditional switch into a smart switch that doesn’t actually directly power anything, you kept the red jumper in place. You can keep it in place, or you can leave it out. It doesn’t matter if there is zero load. You are not really using it in dry contact or wet contact mode in that case. You are using it simply as a controller for something else remote. The jumper passes power from the inputs to the relay side of things in wet mode so that loads can be powered. (It kind of surprises me that the wire jumper provided is so small considering the relay can supply up to 10 amps in wet contact mode. It must be rated for 10A @ 120V even if it seems small to me, though.)

Do you think this could be used to control Town & Country gas fireplaces?

Can you use the switch side as separate switches from the load side? Or if a load L1 and switch S1 are connected, they always work together? I could see some cases to separate them and control 4 different things.

Really like this, but got me thinking - what if instead of powering off or on, my primary want is to monitor power consumption? Have you run across something that could be connected to an outlet to see how much power is being pulled by perhaps a freezer versus a nightstand outlet? Is there a way to bypass the switch element so its not necessarily switchable but just monitors energy consumption? Or have you run across another device that would be better for the energy monitoring?

Pretty neat. How hard is it to pass the settings to the new owners if you sell the house? Having to undo it all would be a pain and the stuff would be useless to them if left in and they don’t know what’s up with it

Your US back boxes are MASSIVE. ours in the UK are under an inch in depth usually because our walls are solid.

Brett, there was mention to the fan light and 'fan'. Is the fan a DC motor fan or an AC? Mentioned in the earlier part of the video was the device works with DC appliances. Is that true with respect to fans?

So do these remember the last state? Eg door shut or light off. Power goes out... Will they stay that way after power returns?

I am wondering does this one work with 3-way switch?

Will this work with a fan that has a remote?

I have a pool panels inside the house you think I can control the pump on and off with the device

Does it need a capacitor for motor control (like your garage) or is an appropriate one fitted internally?

Could I configure my air conditioning with this device?

Can we change pulse mode without an Aqara hub? :-/

So what is the solution for the relay to work with a garage with sensors?

Cool video. Maybe it's just me but couldn't you turn the switches upside down so up is on and down is off?

Is this device UL Listed?

Ok so cool

Hi, I’m in UK, so wall sockets are obviously different, but would it work with wall sockets with built in usb ports?

What iPad are you using? That would be something nice for the wall.

At 11:35, how does it know garage door is open or closed? Do you also have a contact sensor connected? Great video.

Does this device definitely work with 12V DC, as the spec (show in the UK) states 24v. cheers

Does it require a neutral wire, or does it work without?

What /where did you get the power supply for the garage door?

In my testing, a button off the S1/COM1 only works with AC power and does not work on 24V DC power. My use case had to have a button on 24V DC so hopefully that is something that works in the future.

Can you actually power the relay with a 12v? I have tried and it doesn't work. Lights doesn't come on. I tried with a 240v and worked fine. 12v doesn't work. Can you confirm you actually used 12 and not 24? Would the amperage makes any difference? Can't find anything online.

If this needs to be connected via a hub, does this mean that when the company pulls it's servers or folds in a few years, this unit becomes useless and redundant? Also, I've never heard the phrase wet contact and dry contact. Is it the same as indirect contact and direct contact With regards electricity?

brett, what phone is that your using?

Garage door, Homekit - can I set garage door to open 50% (slider, automations, Siri)?

I would like to use it to replace a relay that controls 2 light points, could it be used by using a button instead of a switch?

Hi

Your mom did not look happy lol

hi, does this work with 2 way switch?

Hey there. Any ways to hook it up to the projector? Mine is a BenQ and it is being turned on from standby by one press of a button and turned off back to standby mode by pressing the button twice within short 1 or 2 seconds delay between (to confirm the need to turn it off) anyone done it?

This device appears to be 3 times the price of a Shelly device. Have I missed something? Does it also make coffee? Cheers

I don't see the point in having the relay behind the switch, Aqara sell an dual switch model and it still works even if the hub or Internet isn't working (unless this isn't for lights, as you're using it with a fan, which it's perfect for) it's interesting I did not know that it could also monitor power, I though only the switch model could do that I actually only came to watch a video to see if you actually mentioned what the button does if it's only used for pairing but you did actually mention pressing the button on the relay unit does actually activate the relay like on nest or hive heater controller I am very new to this company and I've gone full on with this I've got the M2 hub the temperature sensors, the 3 x smart thermostats (testing and I can't use them on my other 4 radiators because the valves under the TRV needs replacing or they bounce when nearly turning off, probably replace 4 radiators while I am at it as other 4 are from when we had a conventional boiler from 20-25 years ago and are only single width) and the relay unit I am in UK so use central heating system and radiators on walls

my main issue is the requirement of the "hub". Does it just plug into USB power? if it does then its not an issue (plug in anywhere), if it requires plugged into a computer, then its a no-go for me.

Or you could use a Tailwind IQ3 to make your opener smart

The pool panels inside the house is low voltage

Nice. I don't like it when a company says that you must use their hub. I use many brands of devices. I have a few aqara devices and most work just fine. I have 3 devices that keep disconnecting from my zigbee hub for no reason. All three device are close to the hub or other zigbee devices that also act as a router. LQI is high. Aqara stopped helping when I would not by and use their hub. All my other Aqara and other brand of zigbee devices work just fine. I use Home Assistant and only use local controlled devices. Just FYI.

is there a relay module that you can add into a electrical panel (for the whole home)?

I have sent the last hour to try and get this thing to work on 12 volt. No go. No blue light. Can not recommend at this time.

Hey Brett, I'm hoping you can help me. I watched your latest video and I am wondering if this relay might help me. I have 2 switches to my fireplace. One for the ignition and one for the blower. I installed a TV xStream Voice Fireplace Switch Works with Any Smart Plug. (with Power Adapter and 12" Micro USB Cable). This solved my blower switch but not the ignition switch. Could this relay work. I sent you a email with pictures. Thanks, I'll keep watching your videos for more tips for my smart home.

My inner electrician is screaming about how these devices are against electrical code as it relates to box fill percent.

hi

Adding that wifi module into the 2 gang wall box violates NEC code for box fill requirements.

Alright … I’ll post the dumb question. I can’t get this thing to power on. I’ve tried three different 12v power supply’s and two different relays. Nothing. Never make it to setup. Now what? I’m attempting the garage door install sitting the door with pliers works fine.

Make a Siri shortcut called shut garage / open garage then you don’t have to say turn on /turn off lol

Why not just install two smart switches. Then you don’t have to worry about someone shutting them off and no power

They look a lot larger than shelly.

Having the light switches be opposite is not ideal and mentally would drive me nuts and definitely the wife and fam would complain about it

again how is this significantly better than a shelly relay ?

Why would someone choose to automate a switch or plug this way rather than installing a smart switch or smart plug?

It won’t fit in most switch boxes.

My brain is not processing why someone would install this on lights or fans lol just get a smart switch and you wouldn’t have to shove that in the 2gang box with the switches

No matter?

I'd buy a bunch if it were Thread

Smart plug but not a smart plug

This thing is rated for 100-250V, 50/60Hz/Max.10A , your outlet is rated for 15A nominal... Not a good idea to have it inside an outlet and control one😞

If it can only work with the manufacturers app it’s worthless. If it can work with private apps it’s good.

Kind of lame, just use a smart switch for the fan and light, also that won't work on a security + 2.0 garage door.

Waste of money. I bought some of these and hooked them up to my employees and the didn’t get any smarter.

No good. Misinformation. This controller doesn’t work with 12v. I bought one and cut wire off of it. Will author do something about fixing it in the video?

This seems terrible. Just replace the switch with better tech.

proprietary zigbee hubs are total BS, no idea who would go into such setup or anything that isnt fully HomeAssistant wrangled.

Cycling your RESIDENTIAL garage door is a BAD IDEA. Those small operators and sometimes the plastic belts are junk and will break not to mention the rapid torque change from LIFTING TO PUSHING your door closed will without a doubt greatly lower the life of your operator!; Lazy tech means unwanted IO hacks.

I’m not sure if your video is supposed to be a tutorial or a demo but either way you just fly by zap in zap out of whatever you’re showing and could be the worst demo tutorial video ever.

I can barely get my switches in the switch box. How the hell am I suppose to get this box in there. LOL
