Comments

I have purchased this item to give it a try in the hope that this device is a clone of HEIMAN HS2IRC (https://www.zigbee2mqtt.io/devices/HS2IRC.html).
External converter (see in "external converter" part) which was replicating HEIMAN HS2IRC's device didn't help to get any response from AUBESS device (send "create" device command, "get_list"). Sniffing didn't show reply from device, but I am not very competent in that area.
One thing I didn't try is to revert latest fix of heimen.js converter which force manufacturer to null on message toZigbee for HS2IRC.
This could be a track to explore.
Note that with or without external converter battery level exposure is causing non fatal errors as the Aubess device has no battery at all and obviously can't expose any...

I'm waiting for a tuya hub to sniff the protocol and add the device.

[JoshuaDodds]

I have a similar device that i bought for the same reason (was hoping it was a clone of the Heimann). This one is from Tuya (rebranded by Moes) and looks like it might be the same as your Aubess device. Let me know if i can help with anything would like to get mine working as well. I dont have a Tuya smart hub and this device just came in today so I haven't played with it much yet.

[mak-42]

I've received tuya hub and tried to sniff communication between the hub and the device. I think I know how to made the device receive a command from a remote control and transmit it.
It should be enough to control simple devices (fans, lights, etc.), but is not enough for something smarter like climate control.

It seems the full protocol is quite complicated. I'll try to puzzle my brain over it a little bit more.

Look at the packets which hub sending to the device. Maybe you can see something.

1. "Power on" command of Chinese fan (taught it for the first time):
   {"key_num":1,"delay":300,"key1":{"num":1,"freq":38000,"type":1,"key_code":"A/IEiwFAAwbJAfIE8gSLIAUBiwFAC+ADAwuLAfIE8gSLAckBRx9AB0ADBskB8gTyBIsgBQGLAUALA4sB8gRAB8ADBfIEiwHJAeARLwHJAeAFAwHyBOC5LwGLAeA97wOLAfIE4RcfBYsB8gTyBEAFAYsB4AcrCYsB8gTyBIsByQHgPY8DyQHyBOAHAwHyBEAX4BVfBIsB8gTJoAMF8gSLAckB4BUvAckB4AEDBfIEiwHJAQ=="}}
2. "Power on" command of Chinese fan (same button, taught it for the second time):
   {"key_num":1,"delay":300,"key1":{"num":1,"freq":38000,"type":1,"key_code":"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"}}
3. "Power on" command of an old Dune HD player (selected from the device vendor's database):
   {"key_num":1,"delay":300,"header":"00040ED8010010390015001500150040010004015A00AD00000106015A00560015","key1":{"type":0,"key_code":"00 00 BF 43 BC"}}

"key_code" contains the sequence (in base64) the device sent when it recorded pushing button on a remote control.

[mak-42]

I dug out the documentation of Dune HD player. It says:

All Dune HD IR Remotes use NEC IR protocol. Different generations of Remotes use different NEC IR customer codes:
...
Previous generation (Premium IR Remote + discontinued models): 00 BF
...
IR HEX codes (latest Remote models use CF CF instead 00 BF):
...
POWER 00 BF 43 BC
There is the description of NEC Protocol.

I captured POWER button of an Dune HD player two times and sends it to the device:

1. {"key_num":1,"delay":300,"key1":{"num":1,"freq":38000,"type":1,"key_code":"B08jRhFwAvsB4BUDAVwG4A0DQDfgAxtAD+ADA0Ab4AcPQBPAAwf7AXACXAZwAg=="}}
2. {"key_num":1,"delay":300,"key1":{"num":1,"freq":38000,"type":1,"key_code":"B0gjQhFvAv8B4BUDAVoG4A0DQDfgAxtAD+ADA0Ab4AcPQBPAA0AbQAsPKaBII2IIbwL//0gjYghvAg=="}}

It does not look like I expected. All the ideas how to transform NEC protocol code to the "key_code" value are welcome.

Anyway. I'm going to make a custom script to support this device. It'll allow to learn keys returning the "key_code" value and send keys.

[kds69]

Thanks you so much for looking into it.
Unfortunately, I can't help you on this. We'll probably come into play as you manage to create a script to learn keys.
I actually do have robot vacuum cleaner for whichkeys from manufacturer (navibot) can be found on the net and I'll try in parallel now that I have the structure of messages thanks to you.

[mak-42]

One does not simply write the script. It looks the developers of the device invented a custom protocol incapsulated into ZigBee packets. It requires to sends and received a sequence of ZigBee packets (usually command packets of six types) to transmit one IR command. I still don't understand how to make it right way. It seems it'll take more time when I expected.

[mak-42]

I've managed to send one of previously written ir code to my fan using my awfully written script. It switched the fan on. I hope I'll finish the first version of the script at the weekend.

[mak-42]

I've finished the first version of the script. It looks nasty, but should work.
Please, check if it works with your devices. If everything is ok, I'll make a MR to support the device out of box.

Adding the device:

1. The script file with external converter has to be unzipped next to the "configuration.yaml".
2. Set the Zigbee2MQTT log_level to debug and enable the external converter by adding the following to your Zigbee2MQTT configuration.yaml:

advanced:
  log_level: debug
external_converters:
  - TS1201.js

3. restart zigbee2mqtt.

The device should be recognized and ready to use.

The device exposed three properties:

1. "learnIRCode" - turn it on to switch the device into learning mode.
2. " learnedIRCode" - displays previously learned IR code.
3. "IRCodeToSend" - paste one of previously learned IR code to send it by the device.

Hi! The original Aubess IR device removed from the Aliexpress shop. Now you can by this new one directly from Aubess, I hope this also work with your scripts, but I don't know, what will be the difference:
https://www.aliexpress.com/item/1005004222101838.html?spm=a2g0o.store_pc_allProduct.8148356.1.27453847L42QDD&pdp_npi=2%40dis%21HUF%21HUF%2013%2C001.11%21HUF%208%2C711.89%21%21%21%21%21%400b0a187916527052859052723e9fa1%21%21sh

[nmaster2042]

I may be wrong but I think previous version of the device is always avaliable, see here:
https://fr.aliexpress.com/item/1005003793186067.html?spm=a2g0s.8937460.0.0.3f3d2e0ePuePy3&gatewayAdapt=glo2fra

There is another one, but physically different:
https://fr.aliexpress.com/item/1005003878194474.html?spm=a2g0s.8937460.0.0.3f3d2e0ePuePy3&gatewayAdapt=glo2fra

[sipossz]

Ok as I see the difference is only the power supply: the new one works with 2xAAA betteries against USB charging. I order one, and I'll try it, how it works with your script.

[mak-42]

sipossz, I think the script should be modified for new device, because it should report battery status at least. Please send a database entry when you receive the device and I'll try to modify the script for you,

Hello all.

I have some problems with my newly obtained Moes UFO-R11 device.

First of all, I managed to properly set it up, receive codes, send new codes, set up with HA, so everything looked fine.

But after some time, the device seems unresponsive. When I send the code, nothing happens. I tried to reset everything and start from scratch (of course except the IR code which I already knew), the device worked perfectly. But after some time it had problems (the first command wasn't delivered at all, the second it was delivered with delay, and the third almost immediately). When more time passed, the device looked totally unresponsive.

If I remove the battery, and reinstall it (i.e. "force reboot it" ) then it becomes responsive again.

This is the debug log, when I try to send commands when the device is not responsive:

debug 2022-11-18 01:21:55Received MQTT message on 'zigbee2mqtt/pc_irda/set' with data '{ "ir_code_to_send":"BxcjVBGeAhECgAMDWgaeAsALQAfAD+AHB0Ab4BcDwDPgCyfAG8AHQCPACwPCTZ4CQA/gAwPAG+ADE+AHC+AbI+AHM+ADDwtaBp4CWgaeAhECngI=" }'

The behavior is completely different. To my newbie eyes, it looks like a power saving issue to me. If the device is not used for long periods of time, does it go into some kind of "sleep mode"? If this is the case, any way we can prevent this? Any ideas?

Hi! I just set up my UFO R11 as well, but after sending commands nothing happened. Could you please describe how did you learn codes and send them?
P.S. Sorry, there is no personal messages :(

Hi! I just set up my UFO R11 as well, but after sending commands nothing happened. Could you please describe how did you learn codes and send them? P.S. Sorry, there is no personal messages :(

@Saharok14 I flowed the documentation and used commands, for example similar to this:

mosquitto_pub -h 192.168.1.4 -u user -P passwrod -t 'zigbee2mqtt/bedroom_irda/set' -m '{ "ir_code_to_send":"BUAjkBFb..." }'

To get the code, click on the web interface to send the command (learn_ir_code -> on) and you'll see the result in the learned_ir_code field

[Saharok14]

And I did the same but never worked for me, looks like the device (Moes IR blaster) is rebooting after sending the command (from the Zigbee2mqtt logs, announce of the device after sending the IR command). I already ordered one more, will see what will
happen :) thanks for the information!

[helepeut]

Same problem as @Saharok14. I have 3 of them.
2 are working as expected, they are connected to the same coordinator.
But the 3rd seems to sleep. It's connected directly to the central controller, and I have to remove batteries everyday in order to wake it up. Z2M is telling me that it hasn't been seen since X days / hours (depending on the hard reboot).

@Saharok14 : are your test with the 2nd one better ?
I didn't try with a Tuya hub

Thanks !

[Saharok14]

I just returned it and got a Wi-Fi one. So, this device didn’t work for me…

[helepeut]

:-(
Thanks for your feedback @Saharok14 .
Which one did you choose ?

[Saharok14]

Try “Tuya IR remote Wi-Fi” I just got a first from the list in the local store… in my case - https://allegro.pl/oferta/smart-remote-uniwersalny-pilot-ir-wifi-tuya-11425213322

[LindsayReid]

Is it possible to simulate up a sequential multi key sequence such as "123" to enter a three digit number. I can't "learn" a multi-key sequence or set up a script to emulate one. The remote only seems to want to do one single discrete command at a time.

[andrewcchen]

Awesome, thanks! I have another question. Does anybody know how the ir codes are encoded? I want to control my ac and be able to create my own ir codes. Other people have reversed engineered the NEC ir codes so the hard part is already done. Does anybody know how I can turn the output ir codes into NEC (or bits) or something else that useful?

I figured out (enough of) how the devices custom encoding works to send any NEC command. I wrote a node js function to convert nec codes into this device's encoding. The script and a description of the encoding are here: https://gist.github.com/andrewcchen/f16eb20d19ea64d9f997c470e2addeaa

Can you help me out
Have same device i guess
It pairs in z2m, but then it is always offline
Tried changing batteries, repairing multiple times
Always the same
Lear switch is also inactive

[c4coer]

can you make it work under deconz, thanks

Hi, I guess TS1201 is still not supported. I have no clue how to add external converter. Could sb help me out with this?

Hi everyone! I managed to crack the custom encoding of IR codes used by Tuya IR blasters.
I've documented the format here: https://gist.github.com/mildsunrise/1d576669b63a260d2cff35fda63ec0b5
With this I've successfully decoded codes learnt by the blaster (to use them with other non-Tuya blasters).

Hi @mildsunrise, thank you for your excellent documentation!

Please take a look over here: zigpy/zha-device-handlers#1687.

We have the same device and are working to understand the codes, too.

I found your Gist, and would like to dig deeper on the protocol used by Tuya IR. Perhaps we can work on a conversion tool? I see your FIXME comment... 😆

Many thanks!

it should use the same format, just try it and tell me if decode_ir works.
if it doesn't, please provide some sample strings so that I can take a look :)

Perhaps we can work on a conversion tool?

encode_ir and decode_ir should be all that you need to convert between a signal and a code string accepted by the blaster.

I see your FIXME comment... 😆

oh, no worries, encode_ir already works, it's just that it produces long strings.

besides, I've just implemented the compression so it should now give reasonably small strings :)
much smaller in fact than what the device usually produces (so you can use the functions to further re-compress a code string).

As the script is currently written, would it be possible to send the exact key_code and header to the device like in the last message through zigbee2mqtt?

I did not implement this because I have no idea how to obtain the value of header. Have you got any idea?

@mak-42 Do you still have the sniffing logs for this format ?
I would like to implement this functionality in ZHA but it seems that the zigbee command flow is not the same as the format without the header keyword.

[mak-42]

Do you still have the sniffing logs for this format ?

I'll try if you tell me the command in the original application you want to sniff.

[ferehcarb]

I'll try if you tell me the command in the original application you want to sniff.

It doesn't matter, for example Fan -> Westinghouse -> Power.

Something have changed since the previous sniffing. I have not much suitable remote controls (Smart Life makes me press buttons to add new one).

The codes for lamp remote control (ERA):

{"vir_id":"bf7e96d7bc918d49a2fbih","key_num":1,"delay":300,"key1":{"keyids":186,"type":1}}
{"vir_id":"bf7e96d7bc918d49a2fbih","key_num":1,"delay":300,"key1":{"keyids":1,"type":1}}

The codes for Dune player (I added 2 years ago):

{"key_num":1,"delay":300,"header":"010ed8000000000200700150040015a005600ad06580e74","key1":{"type":0,"key_code":"01$^002000FD28D7@&$%@*"}}

it does not look like the code sniffed before:

{"key_num":1,"delay":300,"header":"00040ED8010010390015001500150040010004015A00AD00000106015A00560015","key1":{"type":0,"key_code":"00 00 BF 43 BC"}}

Thanks for trying, I finally bought a sniffer and a Tuya GW (actually 2 because I didn't know that the wireless version doesn't support the IR blaster...) to do tests more easily.
