I am running crelay on an Ubuntu machine. I am replacing my conrad 4ch card with a sainsmart 16. when I run "crelay -i" i get: "Detected relay card type is Sainsmart USB 4/8-channel relay card (on FTDI chipid EECA5EC5, 8 channels)". I have tried both compiling from source and downloading the latest built binaries.

I have a Sainsmart usb relay card and an ICOM 7300 ham radio that is also usb controlled. Each works well independent of the other. I have tried using different usb ports but I am having usb conflicts. When I type in crelay -i, I get the Sainsmart relay card and a Conrad card marked as icom7300. When I try to use the Sainsmart card, it will allow me to turn a relay on but returns this error 'libusb_control_transfer error (LIBUSB_ERROR_PIPE)' if I try to turn a relay off. I've loaded the driver for the Sainsmart card only.

Is there something in the detection part of the program that I could modify to just have it look for that card and nothing else?

Hello,
I would like to know the USB relay based on HIDAPI are supported or hard to add support?
https://github.com/darrylb123/usbrelay

I'm interested by HTTP API.

Thx

I purchased a Sainsmart 16-channel USB relay. There is support for the Sainsmart 16-channel relay within crelay, but upon further inspection after receiving the card, the card that I purchased (SKU: 101-70-208) is not HID compatible, and instead shows up as: QinHeng Electronics HL-340 USB-Serial. I could be wrong, but I don't think this variety is supported yet by crelay.

After finally finding the serial commands under the sainsmart wiki for the part number, I adapted a python script from pyusb to get it working initially, although I couldn't get the board to return a status (and I purchased two boards), at least the relays would turn on and off:

Hi,

would you mind publishing a new driver binary for the current Raspbian kernel?
Thank you!

Is possible to control the HTTP Server listen on 127.0.0.1?
Thx

Hi Ondrej
Nice work all of have done. May I suggest to add a timer and/or a start/stop time?

Hi all,
I have a sainsmart 4 relay board, with these applications:

• relay 1: not connected
• relay 2: garage door pulse button
• relay 3: 240V light socket with two led bulbs
• relay 4: 240V magnetic water valve

Everything works fine, except relay 4. When I activate the relay through the web interface, the relay gets activated correctly and the page is reloaded as it should be. However, when I click to deactivate the relay, the daemon terminates with this in /var/log/messages:

Oct 26 20:23:39 localhost vmunix: [ 6640.879106] usb 2-1: USB disconnect, device number 4
Oct 26 20:23:39 localhost vmunix: [ 6641.143125] usb 2-1: new full-speed USB device number 5 using ohci-pci
Oct 26 20:23:39 localhost vmunix: [ 6641.335615] usb 2-1: New USB device found, idVendor=0403, idProduct=6001
Oct 26 20:23:39 localhost vmunix: [ 6641.335994] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
Oct 26 20:23:39 localhost vmunix: [ 6641.336475] usb 2-1: Product: FT245R USB FIFO
Oct 26 20:23:39 localhost vmunix: [ 6641.343317] usb 2-1: Manufacturer: FTDI
Oct 26 20:23:39 localhost vmunix: [ 6641.350241] usb 2-1: SerialNumber: AI02JFXJ
Oct 26 20:23:39 localhost vmunix: [ 6641.371600] crelay[2861]: segfault at 40001fd ip b767cee6 sp bf8ca8c0 error 4 in libc-2.19.so[b7607000+16e000]

So it seems the relay board gets disconnected and connected again. Maybe there is kind of an issue with the board itself, which is weird because everything worked fine before when relay 4 was used for a light socket.

When I reload the daemon, all works fine again until I deactivate relay 4 again, after which the relay is correctly deactivated but the daemon terminates again due to this disconnection issue.

I use crelay 0.13. The CLI doesn't work either:

root@alix:~# crelay -i 3

Detected relay cards:
  #1	Sainsmart USB 4/8-channel relay card (serial AI02JFXJ)

Thanks!

libudev won't install until you :

• sudo apt-get install pkg-config libusb-dev

Hi,

Will this project only work in a OpenWrt environment. Or can I get this to work on a standard Linux PC.
If yes, how?
I am somewhat missing How to get this to work for me. And I really would like to get this to work.

Kind regards,

Luc

Hello,

Could this work on OpenWRT (linux-based) routers?
It would be great to be able to control relays with the only device that is turned on 24h/day in my house :-)

Thanks,
Joaoabs

I have 2 channel HID interface relay board. It's successfully running under openwrt in daemon mode but I have problem with controlling it under PiRelay android app. Application have a problem with checking relay status after start and always sets relays as OFF. Is this a problem in PiRelay or my crelay configuration?

Hi - maybe a stupid request, but I can't seem to get multiple relays to fire at the same time (not multiple boards, just multiple relays on a multi-channel relay)

This seems to work fine for me:
curl -d "pin=3&status=1" http://localhost:8000/gpio

but posting multiple variables doesn't seem to work no matter what syntax I have tried so far.

This currently suports the Sainsmart 4- and 8-channel relays which use FTDI, but the Sainsmart 16-channel uses USB-HID, and looks different from the current hidapi driver.

Has anyone tried the Sainsmart 16-channel. A very poor attempt at documenting them is on the Sainsmart page for this part:
http://www.sainsmart.com/mouse-over-image-to-zoom-sainsmart-16-channel-controller-usb-hid-programmable-control-relay-module-kit-sainsmart-16-channel-controller-usb-hid-programmable-control-relay-module-kit-sainsmart-16-channel-controller-usb-hid-programmable-contro.html

Hello. I am still in the early process of learning all things for raspberry pi, and has just discovered this amazing thing. I got it set up and web interface is working. I just have one problem. when i switch the relay(s) on, in my web interface (Probably the same if i use the POST or GET requests.), it gives me an error.
ERROR: Unable to pwrite 1 to gpio value: Operation not permitted
and the same with when i switch it off, of course.
ERROR: Unable to pwrite 0 to gpio value: Operation not permitted

This is probably a easy fix. Any help is accepted. :)

Is it possible to make this work with ifttt? As in, "If You say "turn on relay", then Make a web request" with the webhook applet. Thanks.

In the Readme file, the interactive command line syntax is given as: crelay [-s ] -i | [] [ON|OFF]. For someone well versed in Linux, the syntax may be obvious from the above. But I am not, so it took me a long time to figure out that you have to repeat the crelay command after the pipe. What worked for me was: crelay -i [-s ] | crelay [] [ON|OFF]. I also put "-i" before the serial number. Perhaps you could give some example commands in the documentation to make it clear to newbies.

process_http_request() (and the comandline, I think) can only deal with one relay at a time per call. It would be nice if there was a way of dealing with multiple in the one call.

Hi Ondrej
Thanks for a handy program.
The path to a device, that has no serial number, is changing depending on other factors than physical connection (linux). This makes it hard to configure for multiple relays, of the same kind.
I need a stable identification to a bunch of relays without serial numbers.

would you accept a pull request, with an alternative path, based on HW bus connection?
I would much prefer to contribute to an existing project, rather then creating a new one.
I imagine it will be a rewrite of the detection logic, using the underlying libusb-1.0
I would be unable to test on windows and mac.
Would that be within you scope for this project?

best regards

Hi Ondrej,
I have been using Your Software crelay for some time now. Is there a way to add some kind of access protection? Currently anyone on the local area network is able to switch. An access string (=password) that has to be added to any curl command, could be set in the crelay.conf file. I know this protection is definitely not "top notch", but it should be enough to stop random prank "attacks".
Best regards
Johannes

Apparently the HID path for my sainsmart16 is not stable.
If I unplug the device and then plug it back in again, the path is different.
I can see this in dmesg as I remove and re-insert the device into my machine:

[2332915.679529] hid-generic 0003:0416:5020.0005: input,hidraw0: USB HID v1.10 Device [Nuvoton HID Transfer] on usb-0000:00:14.0-4/input0

I cannot see a good way in the HID API to find the underlying USB path, which as you can see IS stable "usb-0000:00:14.0-4" (and my second device on "usb-0000:00:14.0-1". I am open to suggestions?

Example: Sainsmart 8-channel GPIO relay card. Relays are activated by output of LOW value (0) instead of 1. The result is, crelay web interface first activates every relay and then shows wrong states.

Hi.
Im doing some stuff on an OpenWrt install.
I have a noname generic usb relay card(HMI), that can be controlled via crelay.
Then i add a usb<->serial ttl thinghy.
Either a cp210x or an ft232 thing.. In both cases crelay latches on to those, and wont recognize the relay any more.
I can still use the usb2Serial to talk to the sensor, but the relay is off line
Is there any way to force is, so it uses the correct card ?

Hi,

I am new in using relays, I see this https://www.raspberrypi.org/forums/viewtopic.php?t=110710 Please Help Noobs control 8 channel relay post and issues regarding it.
I have everything installed and I have connected my raspberry pi to a 8 channel usb relay. The device is detected.

pi@raspberrypi ~ $ sudo crelay -i
Detected relay cards:
#1 Sainsmart USB 4/8 channel relay card (serial AI04XQI3)
pi@raspberrypi ~ $sudo crelay 1 on
pi@raspberrypi ~ $

I have it up to the above point. I cannot turn on the relay or turn it off. I get no output!!! Please help. Thanks in advance.

after compiling with "make" and running crelay I got the follwoing message:

crelay, version 0.14

This utility provides a unified way of controlling different types of relay cards.
Supported relay cards:

• Sainsmart USB-HID 16-channel relay card
• Generic GPIO relays

why is the conrad card not listed as supported?
Currently is no card attached to the PC.

On Fedora, libftdi is actually libftdi1, and the headers are in a subdir of /usr/include.
I had to change the Makefile locally to handle that, and also add -I/usr/include/libftdi1 to properly find the headers.
I'm not sure the right way to change the makefile to deal properly on all platforms.

Hi, i’m new to all this linux stuff, but the problem is that crelay sees my 3d printer as sainsmart relay and my printing software doesn’t see printer when crelay is on. How can a fix this problem? I use orange pi on armbian

Can anyone suggest hardware for a total of 48 relay outputs?
Another thing, it needs to handle 16A @ 250VAC (at least for some of the relays)

I apologize if this is not the correct forum/channel for questions like this.

Hi!

I have a problem. I use crelay on my OpenWRT router. It succesfully installed and it control my 1-CH relay card properly.

Unfortunately, crelay always crash after undefinied time (~1 minute - ~1 day). Sometimes a fast router-reboot is enough, but usually I have to re-install the package.

This issue is very weird, because I can't find any reasons. It happens randomly. When I use (switch on/off) the relay, suddenly the web UI disappear, and my web broswer can't estabilish the connection with crelay anymore. Moreover, PiRelay neither. It sends me an error message:

"Pi (server) not detected on network"

Do you have any ideas (or solutions?)

Thank you in advance! ;)

I'm having an issue getting crelay to properly detect my relays; I've got a pair of sainsmart 16ch relays. I'm running crelay on a raspi with either of the relays attached, but the code runs through autodetect without finding them. Any recommendations or suggestions?

Much appreciated!

Great great work! Simply amazing.
Everything went nice and smooth. Installation on Ubuntu 18.04 without any hiccups.
Just wanted to say thank you ❤️ 🚀
