Single channel low voltage zigbee relay

[@EsotericArctos]

I am enjoying seeing these reviews. There are so many options out there now, it is good to see real life reviews.

[@csongorvarga]

Thanks, I also think this is a pretty simple and versatile unit.

Das Ding ist geil! Hab ich 😍

[@michaelw9758]

Sorry if this is too basic, but at 1:50 you mention powering the relay from the same power source as the appliance you're switching. What does that wiring scheme look like? Or am I misunderstanding? I am trying to confirm whether I can avoid having to plug this unit into an outlet separately--by installing "in line" with the low voltage appliance.

[@eddiet3026]

The board receives positive and negative from the power source. The relay interrupts the positive OR negative like a light switch. The other is wired directly to the appliance/light.

[@streptecoccus]

Congratulations, nice review, I have a question for you. I want to use the product on my manual doorbell that works with 12 volts. When I enter the 12 volt device from the line coming to the doorbell and make the necessary settings, I will be able to press the bell smartly from my mobile phone. Can I also operate the bell with the old manual button on the door? Is there a device on this device that I can connect the physical button to?

[@createforpeople]

What about power consumption in sleep mode?

[@74357175]

Very cool! Do you know what the controller power consumption is?

[@RND-USA]

Exactly my question! Did you ever find out?

[@74357175]

@@RND-USA alas, no. I'm actually wondering what the best way to calculate DC power usage on devices like this. We have AC power meters, and USB power meters. But DC power is still best measured with a multimeter, which is a pain and cannot easily be automated.

[@LorenzoClemente]

how much current mA does it draw from the power bank when idle?

[@declanhiggins8029]

I'm also keen to understand this. And to answer the wider question if it is feasible to run this unit via battery in the long term or would it require too many charges or battery swaps to be practical

[@burnjack291]

Can this be used with a 12v house number led outside light to turn on off? (Light at the house number address)

[@martinlawes1]

Great to here that I can connect my 12v led strip lights, but which two connectors do I use please, thats Martin

[@csongorvarga]

The input is straight forward, only two connection. Take the positive from the input, wire it to COM and wire NO to the positive of the LED strip. And the negative of the LED strip connects to the negative on the input. That should do it.

[@martinlawes1]

@@csongorvarga thanks but didn't really Understand could you draw a picture, I thought battery connection go to the 2 connection, and the Strip Light wire goes to two of the 3 connection?

[@martinlawes1]

@@csongorvarga Are got it, will try that then when I get the new one as the first one wouldn't find it on the network, thank you .....

[@lowrider2025]

What model would be appropriate to control garage door motor? I need dry contact zigbee relay that does not pass current to device. Only to act as a momentary switch that connects garage door motor wires for 0.5 seconds (inching mode)

[@csongorvarga]

This is a dry contact switch. So this is a good model for garage door motors.

[@xairoo2k]

Would be interesting if the 433 receiver will only works when the remote got paired and if it works by handshake - otherwise it would be too insecure. Spamming 433 MHz should be considered. Anyway, I'll remove the 433 MHz antenna to be on safe side =)

[@csongorvarga]

Yes, I think that is a good idea. This is my only issue with 443, it is insecure.

[@eddiet3026]

For modules with multiple relays, do you get 10a per relay?

[@venunarukulla907]

will it send a pulse in reverse polarity to turn off ?

[@csongorvarga]

What do you mean reverse polarity? But the answer is no.

[@RND-USA]

Does this have a manual on off mode that does not automatically latch on or off?

[@csongorvarga]

You mean a short pulse? Momentary mode?

[@RND-USA]

@@csongorvarga I’m not sure of the correct terminology 😂 but what's it called when a relay can be turned on or off for an indefinite time (in my case I’m thinking manually, or maybe having the relay turn off power at sunset and turn on at sunrise )?

[@csongorvarga]

@@RND-USA If you want to turn it off specific times, those are usually called Schedules. And you can define these for the device. When you want this for sunset/sunrise, those are automations but work the same way, just set it in a different place in the app.

[@RND-USA]

@@csongorvarga I looked it up 🤣according to this video I’m looking for a basic toggle switch.😂 However I do have uses for latching and momentary relays in the past. I’m glad to hear this has scheduling / time based automation too! I’ve been avoiding the Tuya/Smart Home ecosystem (feel like Homekit using Homebridge to sync Alexa, Yolink DIY ESP, devices with Aqara /Apple is already a lot😅). Hoping there’s a way to automate via Zigbee3 nicely without the Tuya app. Home Assistant is probably the best solution right?

[@csongorvarga]

@@RND-USA Well, I only tested this in Tuya. And to be honest, when I check a particular function, I can never tell what is done on the device and what is done in the cloud. But if you go with Home Assistant it is 100% you can create your own schedules!

[@singlespeedss5617]

Does this works with Home Assistant? Particularly ZHA?

[@csongorvarga]

I did not test it, but I am sure it would. This is such a basic sensor, it must be supported by any Zigbee implementation.

[@visionshades]

Hi, can you make a video or explain how to connect a led light strip to this using the same power supply (12v driver) as the relay?Many thanks 🙏🏻

[@quiglag]

To set up your LED strip, you must first split the Hot (+) and Neutral (-) wires from your power source into 2 pairs. Connect the first set of + and - wires to power the relay. Next, connect the second + wire to COM. Take a separate wire and connect it from NO to the + on your LED strip. Finally, connect the second - wire to the - on your LED strip.

[@BartTech]

When I don't pair a rf remote to it. Is the relay safe from rf signals? I mean, rf is not a safe protocol..

[@csongorvarga]

I would say that it is. Because unless you long press the button, it will not go into learning mode. And it looks like there is no way of triggering the learning mode in any other way (not from the eWeLink or Tuya app). Therefore as far as I can tell, it is safe.

[@LeiChat]

Thanks for the the really informative video. I am looking for a Zigbee dry contact, momentary relay like this that may be powered from 240V AC (UK) to trigger a roller garage door. I don't have a convenient way to run USB power.

[@csongorvarga]

For me it seems that all the dry contact relays need a low voltage power supply. So I am afraid just need an old phone charger which is permanently plugged in.

[@quiglag]

They make an 85-250v version.

[@gasmas21]

how to connect garage door on it?

[@jasam675]

Does anyone have any idea how to set the interval in inching mode? The preset (1 sec) is too long for my garage. Need around 0,2-0,3 sec and I do not want to loose Smart Life/Tuya cloud connection with some 3rd party firmware.

[@gasmas21]

Can you help me with my relay? i have almost the same but no connect to RF. i have fotos to send you if you have time.thnx a lot

[@csongorvarga]

I am sorry, but I don't think I would be able to help from a photo

[@martinlawes1]

Thanks lol

[@slruwanprojects]

app name ?

[@csongorvarga]

Which one, I used Tuya Smart and eWeLink apps.

[@bestekengg]

NO SHIPMENT TO INDIA.

[@larslehmann5832]

hey can I pair it also with an alexa studio ? if yes could you show how ?

[@csongorvarga]

I don't have an Alexa, so I can't show you.

[@metoo7587]

This is way overkill for my application. All I need is a solid state ZigBee controlled switch capable of switching on/off a 5V/3A source. The whole board including the Zigbee circuitry should be powered from the same source so that no extra power is needed to power the switch. How come nobody is making such a device?

[@csongorvarga]

Actually, most of the zigbee switches I have are what you need. Mains powers them and the switch mains power. But for certain garage doors, or other applications you need a simple relay contact. And those all have separate power input.
