Re: compatible 433Mhz USB transceivers?

Fri Jan 12, 2018 11:58 pm

A URL would help. You can turn on email notifications for threads you're interested in so I just got an email.

You can edit a URL into your post or make a new one, but I've seen maybe dozens of transmitters and receivers. Aliexpress and eBay have a lot.

Sorry for that I thought the link in post #1 is sufficient.

I am talking/writting about this one:
https://www.ebay.de/itm/New-433M-CC1101 ... Ciid%253A1

I wanted to try it first on my Windows machine because my linux machine is not very accessible (behind a shelf)
Driver installation seemed to work and then I tried to use a scom assistant for debugging ... without any signal or reaction. So I hoped someone of this old threat found a solution and could share it.

Hmm, if you want to test transceivers you generally buy them in pairs so they can talk to each other. That's a pretty fancy one, the receivers and transmitters I have are basically a single transistor with a crystal. You can find those for around $3. But the two types aren't very compatible.

If you have access to an rtl2832 dongle to serve as a receiver, try running rtl_433 on it. https://github.com/merbanan/rtl_433 I've been using it about a year and a half logging temperature data from an Oregon Scientific outdoor temperature sensor that transmits in the 433 band. It should be smart enough to decode the numbers sent from the other end. As for any software that came with yours I have no idea. You could maybe build rtl_433 under Windows, it's mostly for Linux. You'd need at least a C compiler. Dealing with USB is more problematic under Windows than Linux, you should probably have a copy of Zadig running.

Spend at least the $11 to get a ZeroW and have another Linux machine. $35 for a Pi 3B and it's about 4 times as fast. Actually a Zero might not be fast enough for this, I haven't tried it. Rtl2832 dongles start under $20. There are many brands, I have 3 from here: http://www.nooelec.com/store/

When rtl_433 starts up it lists what drivers are built in, even with the old version I have I see:

Great reply! Thanks

I wondered if my remote control for 433MHz power points is recognized when i press buttons but nothing happens.
Maybe I have to really look for another solution as you proposed.

I have no idea, yours seems to be one of the more complex ones. If the codes don't match up right that could cause it to not respond. With most stuff I've seen, including garage door openers, each receiver/transmitter pair has to have the correct digital code set. It's meant for crowded neighborhoods, you pick a different code than your neighbor, that way you mostly don't interfere with each other.

Mine is much more basic, either the transmitter is sending RF or it isn't. Both systems have their advantages. I see a neighbor's something or other in my temperature data sometimes but I take it out by only looking for a specific sensor model number. And my nearest neighbors are 1000 ft (300 meters) away.

Rtl_433 will read everything it can and list out what it finds, including the codes, like

Code: Select all

2017-11-11 14:23:50 :   Thermo Sensor THN132N
        House Code:      80
        Channel:         1
        Battery:         OK
        Temperature:     -0.30 C
2017-11-11 14:24:29 :   Thermo Sensor THN132N
        House Code:      80
        Channel:         1
        Battery:         OK
        Temperature:     -0.20 C
