I don't think that you are telling us everything. You want a magic wand, but won't tell us why.

Your answers, such as saying you can't open the box......is non-sensible and seems elusive.

How can we give meaningful suggestions, without knowing what you REALLY want to do?

And WHY you want to do it that way. Might be a better way, for whatever you want to do.

Why is getting answers from thread starters, like pulling teeth? Do you believe that we are just nosy?

It's been 40 posts, and I still don't know what a power box or power unit is, or what it looks like, or what it does.

Nor do I understand the un-authorized equipment or it's use..

What country is this in? Is this power box a meter......to charge money?

Questions, questions, questions.

Thats it

 

Ok.....and......so......is that it? It seems to me that that unit is easy to open. It ain't like it takes 10 bolts to get into it.

And it appears to me that any foreign equipment should be easy to spot. An insulated inspection mirror can sweep the rear of the cabinet in a few seconds. Offer a bounty to inspectors.

One tenth of one man-hour/inspection max. 200 mhr total.

Be creative. Call it a pre-warranty expiration, preventative maintenance procedure, that you can give a bulk discount price on. Looking for warranty repairs.

Then offer a cabinet security upgrade to prevent future encroachments. A secure locking mechanism and perhaps an alarm.

Think of all the cabinets that could have already been checked.

 

im working in a lab in which we should check 2000 sealed power boxes every day
one part of those boxes is empty but sealed. some people put this recievers inside those boxes to open them before we check it and they put a new seal on that box. so they can open the box everytime they want.. we should avoid them to put recievers inside the boxes.
we got many many problems here and im loosing my job just because of this.......

Are all of the "receivers" the same? Do they have a common access code? What happens when the receiver is activated?
I'm suggesting you might be able to transmit a signal and it will cause something to happen that you can detect without opening the unit.

 

Someday one of my friends who lived in US said to me "You should explain 10 times for american people to make them understand your question". i remembered this today !
in my country we dont need to explain a question... always there's an answer (i know / i dont know).
no need to explain why i asked this question ... Your ideas about my question so funny for me.

Let’s say you say to me, “I need a car, what should I get?”

I can give you an answer right away. “Buy a Hot Wheels Mustang”.

Is this a valuable reply? It’s all I have to say. If it’s not a good answer, ask yourself why it’s not.

I think you would say " I dont know, check the prices and the brands you like "
If i dont know all the details, I would'nt suggest anything to anyone.

They are working in 315MHZ but the brands are different
No i dont have any command or access code
The consumer make a shunt in his power meter, So the calculation of energy will be turn off

 

i thought that this forum has many literate and educated members who can help in electronics issues
unfortunately i see some stupid and primary comments on my question
i dont see any useful answer
you changed my mind about this forum
Thank you

Actually, you're lack of knowledge is preventing you from understanding why we are all asking the questions we are asking. Instead of dismissing our questions, try to understand what we are asking/stating. The fact that you can't understand us means you shouldn't even be attempting whatever it is you're attempting because it is way over your head.

We aren't responsible for your inability to understand.

And to be perfectly honest, this sounds to me like you're trying to break into people's garages by identifying and taking control of their openers. You haven't given us any reason to think otherwise.

 

As above, I think the use of the word "garage" was an unfortunate choice for a metaphor.

But, BM, I agree with everything else. The hardest thing to teach, or convince a newbie of, is that a good question is W.A.Y. harder to formulate than a good answer.

im so sorry about some fool people like you...
You are some kind of illiterate people who think he knows anything.
My question and the details i put in this forum was so clear and i think lack of Intelligence of some persons like you just made it hard...
once again im so sorry about this forum and some people who commented foolish answers on my post

 

My question and the details i put in this forum was so clear

As clear as very thick black mud.

 

You are some kind of illiterate people who think he knows anything.

Well that gave me a little giggle.

I think the people on this forum are highly intelligent, well informed and patient with newcomers like me. They have had patience when I've repeatedly asked for deeper explanations of things. When I have problems with understanding something, I try to make it as clear as possible to what I'm having trouble with understanding. And the members of this forum have always worked with me to find a way to properly phrase my questions and then go to great lengths to explain the answer.

I'm sorry that you don't feel that way.

 

Well that gave me a little giggle.

Me, too. Everyone knows that Colin and AG are the ones who know everything.

This thread kinda reminds me of one of my first projects. I tried to make an induction heater project WAY too complicated. People tried to tell me, I didn't listen (albeit slightly more politely), and in hindsight......I had learned a lesson.

I'm sorry too. Folks on this forum are here because we want to help, believe it or not.
Isn't it interesting that the consensus of the replies to your question are all along the "foolish" line?
When multiple people from all around the world, from different backgrounds are giving you basically the same answer, all you do is attack because you do not want to accept what is said?
Have you thought for even a moment, the problem may be your end?
You think your explanation is clear, but obviously, you are the only one that does so.
The whole of needing to find a random receiver in a locked box is odd, then you show us an open case.
You mentioned ...

The consumer make a shunt in his power meter, So the calculation of energy will be turn off

That sounds like a case for the police to me.

What does a receiver have to do with that?
Why is there a receiver in some boxes anyway?
What does it control?
You keep feeding small bits of info out and a lot of that can be important.
We are now over 50 posts and we are still fishing for details. For some reason, this is not uncommon for new posters. As has been mentioned above, asking the correct question can be pretty hard. We are trying to understand, but what you are giving is quite a way out of our experience and does not make a lot of sense at the moment.

I do not claim to know everything, but I have had over 50 years in the electronics industry. Working on 100KW HF transmitters, telephone systems, appliance repairs, designing and building industrial control equipment... And more. I am a Ham radio operator, 3D printer nut.. A pretty wide range of stuff. And I have learned there is so much I do not know. That is one reason I am on this forum. Others here have experience and knowledge outside of mine and I can learn from them.
So can you if you listen.
Still, we are willing to help you if we can. It is up to you.

 

I've been watching this topic for awhile and like many I'm puzzled by the possible application. I think @BR-549 got it right, I think the TS is looking for a bug detector but is unwilling to state that.

May i have your Email ?

 

I think we need a fresh start, maybe we can get past the communications issue. I had to go back and read through the posts to get a better idea of the device you are describing. I'm sorry some of the responses were so abusive, I will try to help.

Based on information you provided, I believe the device you are describing is a meter box for measuring electrical power consumption. The receiver you mention is placed in the sealed box by the end user in an attempt to bypass the metering application. They are trying to steal power. Your goal is to detect the receiver device but you are limited to external examination only.

Am I interpreting your posts correctly?

 

Thanks dear
Yes, The end-user put this kind of remote relays between input and output of the meter
So the calculation will be off.
When a meter expert goes there, the end-user turn the relay off. So everything will be normal for the expert
Here is a datasheet i uploaded which has some information about two kinds of conventional receivers in my country. They usually use these receivers in those boxes
