Can this repo work with RM4C mini?

[sangnguyenz]

I wonder if this repo can work with this model (RM4C mini) as link below? https://www.amazon.com/Broadlink-BestCon-Universal-Control-Compatible/dp/B07ZGH8CLL Thanks for your contribution.

[eschava]

It should, do not have a device to check

[sangnguyenz]

Thank you

[sangnguyenz]

@eschava I have a question, can this publish a message from laptop to RM Mini 3 to control the devices? Thank you

[eschava]

@sangnguyenz This utility is MQTT based so you can use any MQTT client for sending a command to the device. For console I use mosquitto_pub

I have an RM4C mini, but am not able to record. The below is the terminal output:

pi@raspberrypi:~/broadlink-mqtt $ python mqtt.py
[2020-04-27 20:59:26,762] DEBUG Connected to 'RM4' Broadlink device at '192.168.1.117' (MAC 24:df:a7:4f:7c:e6) and started listening for commands at MQTT topic having prefix 'broadlink/'

[2020-04-27 21:00:18,951] WARNING No command received

I am able to record commands using the Broadlink app.

Is there anything I can glean at this end to help?

[eschava]

Could you please try to record commands using broadlink_cli utility from python-broadlink package?

[digitlength]

I can't seem to get the python-broadlink package to discover my device.

Here's what I've done:

apt-get install -y git python3 python3-setuptools python3-crypto
git clone https://github.com/mjg59/python-broadlink.git
cd broadlink-python
python3 setup.py build
sudo python3 setup.py install
cd cli
python3 broadlink_discovery

When I run that last line, I get the following:

python3 broadlink_discovery
Discovering...
Traceback (most recent call last):
  File "broadlink_discovery", line 14, in <module>
    devices = broadlink.discover(timeout=args.timeout, local_ip_address=args.ip, discover_ip_address=args.dst_ip)

    cs.sendto(packet, (discover_ip_address, 80))
TypeError: str, bytes or bytearray expected, not NoneType

Not sure what to do from here...!

[eschava]

Hmm. Pretty weird. The same result with broadlink_cli?

EDIT: Ignore all the below, other than as a reference. I now have it working, and the only thing I've done different to what's written below is used python3 rather than python when running mqtt.py.

pi@raspberrypi:~/broadlink-mqtt $ python3 mqtt.py
[2020-05-03 16:10:50,482] DEBUG Connected to 'RM4' Broadlink device at '192.168.1.117' (MAC 24:df:a7:4f:7c:e6) and started listening for commands at MQTT topic having prefix 'broadlink/'

Original comment below:

OK, after patching the python-broadlink source with this and this I finally got the cli scripts working:

pc@pc:~/Documents/src/python-broadlink/cli$ ./broadlink_discovery --dst-ip 192.168.1.117
Discovering...
###########################################

I couldn't get ./broadlink_discovery working without the --dst-ip argument.

I can then use the --learnfile argument for broadlink_cli to learn the IR command from the remote:

pc@pc:~/Documents/src/python-broadlink/cli$ ./broadlink_cli --type 0x62be --host 192.168.1.117 --mac e67c4fa7df24 --learnfile BEDROOM-LIGHT.power

Now, back to broadlink-mqtt:

Great, we're connected to the device, and to the MQTT broker. I now send the following command to the broker:

pi@raspberrypi:~ $ mosquitto_pub -t 'broadlink/masterbedroom/light/power' -m 'record'

And the response in broadlink-mqtt is:

The two strings (BEDROOM-LIGHT.power and power) do not match!

I can run the following, and it works - the light toggles on and off:

pc@pc:~/Documents/src/python-broadlink/cli$ ./broadlink_cli --type 0x62be --host 192.168.1.117 --mac e67c4fa7df24 --send @BEDROOM-LIGHT.power

But if I run the following, it doesn't work - the light doesn't change state:

mosquitto_pub -t 'broadlink/masterbedroom/light/power' -m 'replay'

I have tried overwritting the content of power with BEDROOM-LIGHT.power, but that doesn't seem to work either, unfortunately.
