OK I have resolved my issue by starting from scratch and re-installing everything.
My issue appears to be caused by the old OS I was running – Angstrom – which is what the BeagleBone originally came with back in 2014.
I flashed the latest Debian image to the eMMC with image “bone-eMMC-flasher-debian-10.3-iot-armhf-2020-04-06-4gb.img.xz” – downloaded from https://beagleboard.org/latest-images
I found instructions here useful for performing subsequent updates and disabling unneeded services – https://www.selectiveintellect.net/blog/2021/8/15/setting-up-a-beaglebone-black-with-debian-buster-for-iot
I then installed the Unified Firmware with these instructions – https://openthings.freshdesk.com/support/solutions/articles/5000631599-installing-and-updating-the-unified-firmware

Works now 🙂

I got a hint from another user @sakos on how this could be achieved in this post – https://opensprinkler.com/forums/topic/pre-configured-sd-card-image/#post-41383

Quote:
– Control of relay on legacy Opensprinkler Pi boards.
To assign the relay to a station just configure the station as “RF” and set “0” as RF code.

I downloaded their SD card image to try to figure out what changes they made.
They made changes to the function switch_rfstation in OpenSprinkler.cpp

The function has slightly changed in the latest Firmware 2.1.9(9) from what sakos had. So I took what sakos did and tried to make it work.
What I came up with is this:

void OpenSprinkler::switch_rfstation(RFStationData *data, bool turnon) {
ulong on, off;
uint16_t length = parse_rfstation_code(data, &on, &off);
#if defined(ARDUINO)
#if defined(ESP8266)
rfswitch.enableTransmit(PIN_RFTX);
rfswitch.setProtocol(1);
rfswitch.setPulseLength(length);
rfswitch.send(turnon ? on : off, 24);
#else
send_rfsignal(turnon ? on : off, length);
#endif
#else
if (((char*)data)[0]==’0′ && ((char*)data)[1]< ‘0’) {
//Single zero character of RF code
digitalWrite(PIN_RFTX, turnon ? HIGH : LOW);
} else {
// pre-open gpio file to minimize overhead
rf_gpio_fd = gpio_fd_open(PIN_RFTX);
send_rfsignal(turnon ? on : off, length);
gpio_fd_close(rf_gpio_fd);
rf_gpio_fd = -1;
}
#endif

}

… and it works in controlling the mini-relay!

I understand the PIN used by the mini-relay has been repurposed in the code for the RF functionality.
It would be great if @Ray could implement a way to choose if you are using the RF functionality or the mini-relay.
Perhaps it could be handled with the argument to the build.sh script? something like:
sudo ./build.sh osbo_relay (for the relay)
sudo ./build.sh osbo_rf (for RF)

But for now I guess I’ll have to live with my hack.

Sorry to dig up old thread.
I also have an OSBo and would like to make use of the mini-relay.
I have recently upgraded to Firmware 2.1.9(9).

@nystrom – were you able to get the mini-relay working? If so, what changes did you have to make?

@Ray – I know you said the mini-relay has been discontinued, but it would be great if it was still useable for those that have it. Can you provide pointers on what changes we can make ourselves to use the mini-relay?

I tried to see if I could figure out a solution myself.

This first issue appeared to be:
E: Unable to locate package libmosquitto-dev

It appears that package isn’t available for the BeagleBone.
When I search, there are packages available with a slightly different name:

ubuntu@arm:~/OpenSprinkler-Firmware$ apt-cache search mosquitto
libmosquitto0 – MQTT version 3.1 client library
libmosquitto0-dev – MQTT version 3.1 client library, development files
libmosquittopp0 – MQTT version 3.1 client C++ library
libmosquittopp0-dev – MQTT version 3.1 client C++ library, development files
mosquitto – MQTT version 3.1 compatible message broker
mosquitto-clients – Mosquitto command line MQTT clients
python-mosquitto – MQTT version 3.1 client library, python bindings

So I tried installing libmosquitto0-dev:
sudo apt-get install libmosquitto0-dev

I thought I was on a winner, but unfortunately now I get a whole new set of errors:

ubuntu@arm:~/OpenSprinkler-Firmware$ sudo ./build.sh osbo

And so I am stuck again 🙁

[noski]

I have tried the instruction in the wiki and all the commands worked, but when I disconnected from the internet and rebooted, the time doesn’t get set properly.

ubuntu@arm:~$ date
Fri Jul 17 21:58:17 EST 2015
ubuntu@arm:~$ sudo hwclock --rtc /dev/rtc1 -r
[sudo] password for ubuntu:
Sat 18 Jul 2015 08:05:48 PM EST  -0.714392 seconds

Where do I see the output from the echo commands in /etc/rc.local to confirm what it is doing?

[noski]

Thanks Ray. Just for clarification, for the relay, by slightly bigger you mean v1.0 is rated 120VAC/2A and v1.1 is rated 250VAC/3A?

[noski]

Hi ray, is there any difference between v1.0 and v1.1 other than change in layout?
Openlab in Australia is still selling v1.0. Just want to know if I would be missing out on something new/important if I bought it?

[noski]

Hi danico, I joined the forum so I could enquire about your setup as it sounds like something I want to do. Can you provide more details? Did you get it up and running?
Is your ‘storage battery’ 12v? Are you connecting it directly to your opensprinkler or are you converting it? What types of lights are you running?
