Probs with 433MHz remote

[Daniel Lowicki]

Hi everyone,

on this product page...

https://www.banggood.com/433MHZ-Remote-Controller-for-DIY-Smart-Wi-Fi-Wireless-Switch-p-1038027.html

.. it tells me something about a black button .. which doesn't exist.

Youtube vids tell me to press A+B in combination (it gets a bit wilder) .. but this doesn't work either.

Can anyone give me a hint .. about how to reset this remote?

Cheers,

Daniel

What device are you trying to control?

This is a transmitter and can't be reset, it's the receiver that will have the black button or similar depending on what it is.

My last challenge ist to copy code from one remote to another .. again all instructions I find are different .. if you have another bright idea you're very welcome.

[Glenn Chapman]

Try holding button A down and pressing B 3 or 4 times

[Daniel Lowicki]

no :-(

[Glenn Chapman]

When you press A& B together are you ensuring you press both at exactly the same time and you hold them down until the led starts flashing?

[Daniel Lowicki]

they don't start flashing .. they don't show whether a key is programmed either. I only see a constantly blue LED (as soon as a key is pressed) no matter how long I hold anything.

[Daniel Lowicki]

In the Q&A a user has asked about cloning .. the reply is .. no :-(

I have as many failed remote fobs as successful ones.  Unfortunately, they are extremely troublesome devices.  I can only give you three pieces of advice;

1. Trawl the internet and youtube and try the various different methods to get them into cloning mode as you can.

2. Order several from Aliexpress.  I found these to be the best

3. Do not try and get help from China - it will drive you insannnnnnnnnnnnnnnnnnnnnnneeeeeeeeeeee!!!!  If they don't work throw them away, crack open a beer and listen to Enya.

I wish you all the best

If i have the wrong end of the stick ignore me, but it sounds like you want to pair rf buttons to the 4ch relays??

fwiw i use similar keyfob 4 button controllers,,  

to pair a button controller use the tasmota console and the RFKEYX command  (check the wiki commands page) rfkey1 for button/relay1, rfkey2 for button/relay2 etc...

once issued the sonoff should beep, then all you need do is press the button on the rf controller you want to pair with that relay/button and if the sonoff receives the signal ok (within 60 seconds iirc) it should double beep and of course output the success messages in the console display..

[Daniel Lowicki]

Pairing is not the problem. You need to double tap a button and then you go into pairing mode .. very simple. But I cannot pair two remotes with one button. So I miss the clone function.

These remotes are made just for one device (they tell me) .. it even sais so in the first line of the bullet list. Since they all look alike I didn't pay attention for this detail. They are supposed to have a fixed code .. so maybe more remotes work in that scenario. Strange that I could pair them anyway .. maybe the 4ch is smart enough to adapt.

Ahh  to achieve multiple Rf controller buttons resulting in the same result a bit more needs adding to the equation.  

I use a rf bridge and nodered
the rf bridge receives all rf signals it can decode and echos them as an mqtt message, while you can pair upto 16 controller buttons to a rf bridge   the only difference between a paired button and a non paired button in the resulting MQTT topic/payload generated is the paired key value in the payload is 0 for unpaired buttons and 1-16 for paired buttons..  

So your control system in my case nodered can subscribe to the bridges messages and decide if the button pressed warrants further action. 

funny thing tho i wanted to cut n paste a few bridge mqtt examples but after upgrading to the latest f/w its stopped working   aarrgghhhh!!!  well it is the weekend..  

[Daniel Lowicki]

Your scenario is very complex .. mine is much easier .. I assign one remot to the 4ch's buttons .. and then simply clone the remotes. Doing this already with non-sonoff things .. no problem at all. But the remotes need to support cloning. So this is actually an off the shelf functionality .. no coding required :-)

[Greg from Oz]

I am using a RF fob like you have and I also have the sonoff rf bridge.

I flashed the sonoff rf bridge with Tasmota.

I didn't bother pairing the rf buttons of the fob as it sends out a unique code that I capture with node-red.

I have 4 rf remote control fobs and some of those have more than 3 buttons. I have them in different rooms and they all control different devices in the rooms but they ALL talk to the sonoff rf bridge.

Here is a post I did earlier:

https://groups.google.com/forum/#!searchin/sonoffusers/nodered$20sonoff$20rf%7Csort:date/sonoffusers/ezxDg0d9HQE/-9-OfbVoAwAJ

Basically what I am doing with node-red is seeing what code is received from the remote and depending on that code I send On or Off to the relevant device. Pretty simple stuff once you get your head around the concept. There might be a better easier way but this works really well.

Its easier with node-red......just saying.

[Daniel Lowicki]

Let's check if I understand this.

The rf bridge is made for you to be able to control RF devices via App. In our case it would be Tasmota app i.e. anything that you could do via ioBroker .. FHEM etc.

I don't see how this could be of benefit to me since I control a 4ch via RF remote which is controllable by Tasmota etc. by itself. So ultimately functionality seems to be 1:1 identical.

Plus .. the distance the remote could cover to control my 4ch would be depending on the distance of the remote to bridge + bride to device .. in my scenario I'd need to have the remote close enough to the 4ch itself.

Let's think about this scenario .. the RF bridge is in the house and you want to open the gate from your car .. arriving at your home. The RF remote is near the gate receiver .. but otherwise would have to reach the bridge for the gate to open.

Did I get this sort of right? If you still think it's recommended in this scenorio .. please help me understand better.

So you have the 4 channel pro?
http://ewelink.coolkit.cc/?p=458
If so then you should be able to allocate one button on the remote to open and close one of the relays on the 4 channel device.
If you don't have the pro version there it's no rf option on it and you would have to use Wi-Fi argue egg rf bridge off you wanted the remote control.
At least that is how I see it.

[Daniel Lowicki]

Exactly .. I have the 4ch Pro R2 .. sorry if I forgot to mention .. and the one remote I have works fine .. I just couldn't clone it.

I get it now .. the rf bridge is to control any wifi device via RF. Interesing .. and definitely something I will keep in mind. I just couldn't figure how it helps right now.

Thanks!

[Greg from Oz]

It may help you later on because if you use the node red option you can use lots of remotes with unique codes and you can make them all control the SAME device if you wanted to. Instead of cloning the remote to control the device you make node-red control the device but with a different remote (if that makes sens?)

The rf bridge gets the remote control data and passes the command via MQTT and then you use what ever you want to control it.

Below is from my rf bridge and I used a remote to turn on my light and then off again.

16:31:21 MQT: tele/rf-bridge/RESULT = {"RfReceived":{"Sync":9840,"Low":330,"High":900,"Data":"D578AF","RfKey":"None"}}

16:31:32 MQT: tele/rf-bridge/RESULT = {"RfReceived":{"Sync":9740,"Low":310,"High":930,"Data":"D578A7","RfKey":"None"}}

In node-red I look for the Data D578AF and send an On command to the lamp sonoff via MQTT

As you can see above I use 3 remotes and they could all turn on the same lamp if I wanted to do that.

When node-red sees D578A7 I send an Off command to the light.

[Daniel Lowicki]

Nice thanks .. at the moment I do these kind of things via voice commands (Alexa/Google) .. I also control the channels on the 4ch that way .. the remotes are  more for my family .. who don't like talking to things :-)
Like this I don't need to look for the remotes and I can also switch stuff in the dark.

A RF bridge sits and listens for RF signals it can decode (its not a complete set) when if receives a signal it can decode it issues a MQTT topic/payload which includes the code it recieved from the controller/sensor/alarm

So with control s/w like openhab nodered etc you can subscribe to the bridge signal topic and test the code recieved and instigate the action needed/required such as opening your gate via a further mqtt message.

to add a further button to the set of buttons that performs action-X  all you need do is watch the RF-Bridge console interface while activating the rf device/alarm/button,  if decoded a mqtt response will appear in the console window and you can lift the code for insertion into your control s/w..  

Range is an issue if your home spans a wider range than the bridge, I dont have that issue but adding a 2nd or 3rd bridge at the perimeter of your home may solve that..

btw current tasmota release may have a rf bridge specific bug i did an ota upgrade last week and when posting the suggestion above i realised its not receiving ANY rf signals atm..  as its currently only responding to 'Over-watering of the tomatoes and beans its not really a high priority to sort out asap but i am sure i only need to download (check my downloads for) an earlier release, for now.
