Add support for IR blasters

[lindsaymarkward]

Thank you for your work on this integration.
It finds my Tuya IR Blaster, but when I try to add it, I get the error:

Connection to device succeeded but no datapoints could be found. Please try set-up again. If problem persists, create a new issue (including debug logs).

I see that the upstream repo has an unmerged PR: rospogrigio#1597
thanks to @ynsgnr
Can you please look at this PR and see if you can add IR blaster support to your project?
Thank you.

Hello, I have answered this before here #81 however I know it's possible to make localtuya sends commands through IR remote, however thanks to the PR author and the original author mentioned in the PR topic it's looks it possible to send IR signals, But the PR you mentioned is completely uses "button" platform as a button entity to sends IR signal unlike the upstream this fork uses the button platform for other purposes as well.
I don't I won't add it, however, I don't have Tuya-based IR Remote for now I may buy one to see if there's better way to handle this.

[lindsaymarkward]

Thanks for the prompt reply!
I have a cheap IR blaster that I want to use to turn my air conditioner on and off. A button would work fine for me.
I understand that the "button" is like a quick fix and you want a better solution.
Thank you for looking into it.

from two options

1. should we rely on the method you mentioned in and get the IR Keys from cloud.
2. We use learn and send command on ha remote this way we learn the button in HA and use it later.

Update: If you set the DPID to 0 go to re-add the device and choose DPID 201 and receive id default 202

note: saved buttons won't be deleted even if you deleted the device.

Hi xZetsubou and lindsaymarkward, could you guys help me please? I cant seem to learn the command. i get the error Failed to call service remote.learn_command. Failed to learn: Power.

I added the remote (didnt input anything for the manual dpss during setup >>>> configured device manually >>>>chose Remote>>>>> under DP ID ... I had 201 >>>> I named it Study IR>>>>> show the entity in this catgory = none>>>> receving signals DP is set as 202.

Then I went to services under developer's tools.>>>>Service: remote: ealrn command>>>> CHOSE THE DEVICE - Study IR >>>> Device ID to learn command from = "Study Aircon">>>>> Command = "Power">>> Command type = IR, Timeout = 30secs>>>> call service>>>> went to press the remote power button at the device but get bacl the error msg Failed to call service remote.learn_command. Failed to learn: Power

Can anyone help me ? What am i missing please?

@Minniemie Post your device diagnostic. You can download it from the device page in HA.

Strange the remote stopped working today. Had to re-add the device. The values look different now

[lindsaymarkward]

Mine stopped working a few versions ago, but I haven't made time to troubleshoot. I was hoping a new version would fix it, but I'll try re-adding the device soon.

[lindsaymarkward]

I just deleted the device and re-added it, setting the Manual DPs to 0 (because I got the error in my first message at the top of this discussion the first time). It worked and I did not need to re-add any of the configured buttons. Happy again :)

[xZetsubou]

I just re-test it on "beta4" and it still works fine for me try it. @Minniemie does the device LED light on when you submit learn command ? also the device diagnostics you posted isn't full so I can see how did your device configured. :)

[Minniemie]

Hiya Zetsubou - yes the blue light turns on but then again its always on. will try to re-add it again Could you have a look see at the steps beloew to see if I did it correctly? Thanks a bunch !

Delete the device and re-add it using the latest beta version to ensure the issue still exists on beta.
HACS -> Localtuya -> re-download -> toggle on beta version.
Ensure to select any other version then select beta5 back. then install -> restart HA re-add the device.

If the issue still exists you will need to enable the debug for both "device and integration" then try learn/send command using smart life this will reports logs post it.

[Minniemie]

gave up on this haha. i think its either my devices (I had 3) have issues or something els ewrong that I'm doing =( went to buy 3 broadlinks hahah. Thanks again for your help.

[xZetsubou]

If you can add the device and check the debug for the device and enable debug for integration as well it will be clear of what happen, when you enable debugs try learn/send from HA then again try learn/send but using smart life. then I can tell what actually happen and help you :)

Just wanted to add a bit there, as I managed to set it up with a completely random Chinese IR device, thanks to wonderful @xZetsubou new commits and a bit of tinkering.

First step is adding your device with 0 in the DPS field:

Once you've done that, you can usually hit the "reconfigure device" option, and tick "Add new entity".

Most tuya IR devices have 201 and 202 as DPS but it will likely be auto-recognize. Select "Remote" as the device type, then check for those 201 or 202 code. One is marked ir_send, the other ir_learn or ir_receive I believe.

Add both of those entities, and turn them on in your device (they should show as turn on/off switches.

From there, head over Developper Tools > Services to start leaning your commands. This is the start of the tricky part (if there's an easier way, I'm curious to know)... So read till the end so you don't forget to save command names if you don't have SMB.

The setup should look like that:

• Service:

Remote: lean command

• Device ID:

A unique identifier you want for the device you are building / learning commands of

• Command:

the name of the command you will learn

• Command type:

only bother if your IR receiver has both ir/rf modes

• Alternative:

self-explanatory, for devices like Aircon remotes that send different signal for On and Off buttons with a single button

Hit the "Call Service" button, likely your IR receiver will turn its LED on to show it's ready to receive. As soon as you press the button on your Device's remote, the "Call Service" button will flash as a green checkmark to tell you it saved the code !

As I mentioned, you should read till the end because...the codes are stored locally in your storage. So 2 ways, either you save the exact names of the commands you just learn along the way (I obviously didn't), or you enable Samba integration and do a bit of digging...

You must enable "Show Hidden Items" and go to the .storage folder:

From there you will find a file called "localtuya_remote_codes" where all your commands were neatly saved !

If you want a bit of a headstart with how to build useful buttons, automations/scripts and helpers with that, I found a quick video that essentially goes thru the same process than us with Broadlink in a short time and summarizes what I explain above (altho not thru our marvelous localtuyaxZetsubou ;-) )
