Question

Anybody has experience with ZMB9-125 ARD? It is a wifi circuit breaker. In the user manual they just say put the red switch in Pairing position then it should flash but doesn't. The status ligth is red then a kind of purple but never flashes. Any suggestions?  

Answer 1

Keep in mind I'm searching for someone having experience with that stuff, not comment about how dangerous it could be  

Comments

@tamarau15972, I appreciate you are not worried about the danger, just make sure it passes CE and you are not going to invalidate your insurance etc as a house fire with suspect devices fitted will null any payout.  

---

@tendentious thanks good point. I won't use it as fuse, just circuit breaker

---

@tamarau15972, it's an interesting piece of kit, where did you get it? With the WiFi, can an electrician still lock it off for safety?  

---

@tendentious the famous from A to Z  

---

And yes can use it 'manually'

---

If you lock the MCB in the off position, I assume WiFi can't turn it back on?  

---

@tendentious yes you can, that's the beauty of the equipment

---

@tamarau15972, if we are talking the same thing, that definitely not legal in the UK unless it's made very clear on the distribution board it's in. Can you imagine an electrician locking the board off to work on it and someone turning it back on with WiFi? Definitely wouldn't meet regs or code here.  

---

@tendentious you are correct. That's why it won't be in the main board but a separate one juste before the pump

---

@tamarau15972, yea, I am gonna have to look at the regs as I am not sure how to get around it in the UK. It's incredibly dangerous so not sure a label would be enough. I like the idea though. Just maybe not looking like regular circuit breakers.  

Answer 2

Would not trust that to trip if needed.  

Answer 3

I imagine when it switches to purple, that’s the flashing. But I agree with @fort3, I wouldn’t depend on that thing actually working in the event you needed it to protect you from death.

@trainload just testing. Later maybe to switch off water pump remotely

---

@sorption correct

---

@trainload not recognized when fixed purple. Thx for trying

Answer 4

Couldn’t you do the same thing with the sonooff switch ?  

Comments

@sonja could 4ch pro then 4 64amps relais but here all in one

---

@tamarau15972 oh I see !  

Answer 5

Once powered up Can you find it on your wifi search? Normally has a number on the side of the device. I've used something similar.

@pavyer nop wasn't in ap mode. I checked  

Answer 6

Why would anyone want a wifi circuit breaker?  

Comments

@aboral that's when you just turn off the water main

---

@cards my RV’s HVAC system has an integrated thermostat so I can’t remotely manage the temperature in the RV while it is parked. With a smart breaker I could at least turn on the AC or the Heat (Whatever I last left it set to) before I leave home and have my RV at a decent temperature when I get to it. Right now I am having to get to my RV, turn on the heat and then wait 2 or 3 hours before the interior is warm enough that I can take my coat off. I’d love a smart breaker.  

---

@forlini a Honeywell thermostat will do all that right from an app on your phone. You don't need anything special for it.  

---

@cards not on an RV HVAC.  

---

@forlini I'd bet you could make it work. I can on my boat.  

Answer 7

I found the solution!  

Answer 8

The red switch is the equivalent of the onoff button. So you put it for 7 seconds to Pairing AND THEN BACK TO NORMAL POSITION. Black magic it flashes blue and I was able to add it in Smart Life App. Thanks for trying guys. All the best in the iot world.  

Answer 9

You sure all three legs (or at least a certain leg) don't need power to power the wifi and other circuitry?  

Comments

@sorption correct, as stated in the user manual. Did you see that I found the solution.  

Answer 10

Personally I would use a contactor that I control via a smart switch. It would feel a lot safer.  

Comments

@garrison9230 yep juste more diy.  

---

@tamarau15972 Yeah, buy two things and connect them with one wire to have a safe product instead of an unsafe one. Not a hard choice in my book.  

Answer 11

I hope you're not in the United States because those are probably not ul listed otherwise those wont meet fire code requirements. Sorry for the voice text typo

Comments

Some people just don't proofread what they type.  

Answer 12

This looks like a device designed to be permanently installed in a residential breaker box. It also looks like it came on the cheap boat from China. Are they UL listed? Sorry if I’m raining in your parade, OP, but direct-shipped Chinese products with no UL listings have been responsible for hoverboard, vape pen, and other LiON fires. I’d just want to ensure they really do break when triggered and don’t fuse close. Great idea though!  

Comments

@sorption Oh I agree, I’m typing this on an iPhone! CE is a good one too. You seem like you know what you’re doing. I felt the media never pushed the message out that although we can buy items direct from China now through so many ways, many are not sold in stores for liability reasons so we have to be extra vigilant when looking at these products. And yeah - I’m betting China and Korea supply a majority of my own electronics.  

Answer 13

Unbranded, Chinese, in your distribution board? You're brave!  

Comments

As opposed to branded Chinese? Because you should look at the “made in” label on your breakers. Most of them are made in China.  

---

To the standards of a major European manufacturer, yes. Are these cerified BS EN60888 & CE by someone you'd trust?  

Answer 14

I could totally use this where some smart outlets need to be power cycled in order to reconnect, which is super annoying! I would not, however, trust this packaging. I would have to buy from a reputable brand.
