Re: Controlling an RF thermostat

BTW, some relatively old WI-FI capable thermostats support simple REST-like API that can be easily used from any application via HTTP requests. For example, I bought thermostat in my house more than 7 years ago and it supports this API. I think that any of thermostats with trademark "Radio Thermosta...

Re: Receiving data from temperature/humidity sensors with cheap RF 433MHz receiver

Hi Vladimir, Too many questions at once :). I suspect that you can speak Russian. Please consider contact me directly by email or Hangout. You can find address on readme page on Github. I highly recommend to use f007th-send instead of f007th-rpi_send because it gives better results. The difference i...

Re: Receiving data from temperature/humidity sensors with cheap RF 433MHz receiver

Added new option -H <port> . If this option is specified then the utility will also serve HTTP requests on this port and send JSON file in response with current values of all thermometers. An example of JSON file: [ {"time":"2018-12-29 16:56:47 EST","type":"F007TH","channel":1,"rolling_code":207,"te...

Re: Receiving data from temperature/humidity sensors with cheap RF 433MHz receiver

I have implemented support of yet another temperature/humidity sensor: Auriol HG02832 (IAN 283582).

Merry Christmas!

Re: Ambient Weather F007TH with cheap RF 433MHz receiver

Let's start with simple questions. What are you going to achieve in your scripts/setup? I can just guess that you probably want to visualize the data on some web page. Then I don't think that you have to integrate this utility directly in something like php script. Basically you need something to st...

Re: Controlling an RF thermostat

Hacking of RF protocols requires a lot of experience and some times good luck. You can look at my project where I was able to implement receiving and decodin...

Re: Multi protocol RF decoder

It is impossible. Some sensors have FSK modulation. But even for ASK/OOK modulation there are many different protocols. Actually all senors have unique protocols and just some of them are similar to another and can be decoded to some degree. For example, there are descriptions of some of these proto...

Re: Radio sensors for weather data

Everything is possible if you put enough effort and money :). I did it but with other sensors. In fact a protocol for each such sensor is unique. Basically in my project I can receive temperature and humidity from following sensors: Ambient Weather F007TH AcuRite 00592TXR/06002RM LaCrosse TX7U (prob...

I have updated the utility. I added support for sensor LaCrosse TX7U. Sensors TX6 and TX3 may also work but I don't have them and I cannot test it. Please also note that these sensors send separate packages for temperature and humidiry and as result the utility handles then separately. JSON package ...

Re: RF 433 Mhz receiver only works at 3 cm.

From my experience this module is bad. I had 2 of them. One did not work at all. Another one works but has bad reception. I would recommend RXB6 or RF-R-ASK modules. Both of them work fine with 3V and you can connect them directly to RPi. RXB6 module (I got the link from the list of recommendations ...

Yes, I added antenna. I would say that with good receiver and not very long distances antenna it is not so critical.
