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

Major update of the utility. In this update I have introduced an experimental support of MQTT. Now it is possible to configure the utility to send data and/or command t MQTT broker. You can define rules that will controls what messages should be send and what conditions for sending them. There are 2...

Re: Portable wireless temperature sensors

Look at my project. I hope it will be useful for you: https://github.com/alex-konshin/f007th-rpi There is a thread about this project on this forum: https://www.raspberrypi.org/forums/viewtopic.php?t=173023 Basically it allows to intercept radio messages from such sensors. Then you can send it to ot...

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

I have updated the utility. In this update I focused on some usability improvements. Introduced configuration files. Configuration file can contain any command line options (long form only) and commands that cannot be passed on command line. Currently there is just one such command sensor that is de...

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

I have updated the utility. Implemented support for sensors FT007TH (Telldus or Renkforce), Fine Offset Electronics WH2. They use the same protocol but despite of similarity of their name the protocol is completely different from the protocol of Ambient Weather F007TH. I have no such sensors. I test...

Re: Interpreting Data from Weather Station

So, you can use RTL SDR dongle and decode it with rtl_433. B...

Re: Controlling an RF thermostat

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...

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...

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: 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...

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 ...
