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

I will take a look during next weekends. I briefly looked at it and it probably will not be a problem to implement it but I will need your assistance because I have no such sensors. Basically I will need examples of data from these sensors that I can use for testing my decoders. Please contact me by...

Re: Straightforward / bulletproof temperature logger

My utility https://github.com/alex-konshin/f007th-rpi supports DS18B20 too, despite the fact that the main purpose of the utility is to work with RF sensors. It can push data to InfluxDB, some REST server, and/or MQTT server. It can also work without any server because it has built-in HTTP server. H...

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

I have just released version 5.2 Changes: Added support of sensors TFA Twin Plus 30.3049 (also known as Conrad KW9010 or Ea2 BL999) . So far I do not observe any problems with this sensor. Added configuration command "dump" that instructs the utility to write received sequences to the spec...

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

Happy New Year! I have a present for you. I have released version 5.1 and so far I do not observe any problems. What is changed? More code refactoring. The goal was to separate sensor-specific code from common code. More work needs to be done but now it is better than it was before. Added support of...

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

This program looks AWESOME. And thanks for all the gifts you have created for us Alex. I do have one "small" problem though. I am trying to load it up on my Pi3 B with gpio 27 and all I am getting in the terminal after attempting to execute "sudo f007th-rpi_send -A -C" for testi...

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

I have reworked an example of HTML page. The previous one used Charts.js. It works but it has an issue: even if I specify options.scales.xAxes.distribution='linear' then it is still not linear. It looked odd. Then I tried to implement the same with MetricsGraphics.js. I could not make it work, it fa...

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: 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...

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

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: 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: 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...
