433 MHz Transmitter & Receiver
Hi,
3 Cables, one 433 MHz Sending Modul and one ESP, and it´s running fine:

The used library also supports receiving.
best wishes

Re: 433 MHz Transmitter & Receiver
Sorry to ask, what the point?
Don't speeak german.
And the Wifi modul ja has Wifi?

Re: 433 MHz Transmitter & Receiver
Nice one
I will try if the el-cheapo switches (Impuls Action) are working with this.
It is sort of RFXcom but much cheaper.
Switching these devices with MQTT (node-red) would be nice
@asm7100.
See it as an interface between wifi and 433mhz stuff.

Hi NietGiftig,
".. if the el-cheapo switches (Impuls Action)....".
Did u had a link?
The used chip in the transmitter is a HX2262, normally designed for IR Remotes.
U can recogniced them at the 5 DIP Switches in the transmitter, i thought these parts are the lowest-cost on the market.
best wishes

Re: 433 MHz Transmitter & Receiver
I use RFLink to control 433 Mhz devices with domoticz and it works very nice
http://www.nemcon.nl/blog2/
I hope for a version with 433 Mhz and 866 Mhz together

The problem with the el cheapo switches is that they all have slightly different timings
http://wiki.pilight.org/doku.php/impuls
I believe that the impuls switches use an LP801
I have also the rflink, but unfortunately the Impuls switches are not working.Ger wrote: I use RFLink to control 433 Mhz devices with domoticz and it works very nice
The developer has some timing problems, but he is working on it.
But with the rflink you also need to buy an arduino mega and it takes an USB port on the Raspi.
If you can use the ESP8266 and an simple transmitter it is cheaper.
And you can make very simple for every floor in the house an 433mhz access point witch is accesseble with Wifi (browser/app/...).

It would be cheaper and it would also solve the problems when having different floors.
It would also make it easy to make an 866 Mhz version.

Re: 433 MHz Transmitter & Receiver
I wouln't count to much on extended wireless support on the esp easy.
The RFLink is the perfect device for all wireless communication. Esp devices are cheaper, but come on... on Aliexpress.. what does a arduino mega Costs you? William, the developer of the RFLink is one of the best wireless protocol developers / reverse engineers. If there are timing issues with cheap ass action receivers he will fix it if that's possible. It might be questionable whether the few euro's per device will make a lot of difference given the fact that at Bauhaus 3 switches + 1 receiver (KaKu) will cost you about 21 euro's. Good quality widely support and proven stability.
Besides all that, the origin of this project lays in the nodo project, using nothing else then 433Mhz communication. The problems we where facing at that point where besides heavy use of this band, distortion, security and range issues, where the reason the developers looked at alternatives.
So yes, i agree a little support for wireless 433 communication might come-in handy, e.g. i have some 433 range issue's. If i could have one esp module capable of sending kaku signals when receiving a http command, it might be handy. As some kind of smart "repeater" (without repeating, just as a de-central sender). I will place that device on the second floor to be sure the signal is received.

Nevertheless it's a pity, but it is your project as i understand, so you have every right for this decision.
And so there is wireless and wireless.rtenklooster wrote: The RFLink is the perfect device for all wireless communication.
RFLink does not do wifi but has to be connected with USB to the HA server.
So "all wireless communication"is not completely true.
I understand that you like the work of William, that's alright so!
I have had some mail exchange with him and he is very helpful.
But at the moment my switches do not work with RFLink
Yes but I'm perfectly happy with my exsting switches (there working good with their own controller and with other projects with Arduino's) so I don't want to throw them away because of all the problems you describe.rtenklooster wrote:Besides all that, the origin of this project lays in the nodo project, using nothing else then 433Mhz communication.

So the combination of WiFi (ESP8266) and Arduino code for the 433mhz part is nice for me if it works.
Combining the old and the new until the old has aged to much, and that without investment.
Ah, Glad you agree to that!rtenklooster wrote:So yes, i agree a little support for wireless 433 communication might come-in handy,
Re: 433 MHz Transmitter & Receiver
This can be usefull to extend 433 range.
I'm using RFLink since his beginning, i try to help by testing more and more new plug ins and try to made supports for french people.
I'm facing a problèmes : my wind sensor is an Oregon and RFLink can't get it because he is too far (on house roof), i need still use my rfxtrx just for this wind sensor.
If Esp can be place on half way to catch RF signal and translate it via wifi to my PI it will be perfect !

Re: 433 MHz Transmitter & Receiver
OpenMQTTGateway or mqtt433gateway on GIT have that almost solved.
First uses RC-Switch to decode, the second uses pilight.
The second is working better for me still teething out issues though.
