Home Assistant and IR gateway problems

And when pressing your remote control do you see a “datastring” on your mqtt broker?

That’s the thing. When using clients like MQTT.fx or MQTT Explorer I don’t see any topics pop up in auto discovery when I press buttons on the remote. I see led blinks indicating it got the message but that’s it. All I did with the default config was to disable gateways other than IR, disable wifi manager and put all my connection details (network/mqtt) in the user_config.h. I dunno, maybe I’ll reflash with defaults and change everything in WiFi Manager :?

Been a while. I redid my setup with Wemos D1 Mini with IR shield and still can’t get the gateway to work with my Haier UNIT.

IRdump works, decodes the key presses, but with OMG I get unknown and nothing is posted to the topics. I tried sending codes I got to IR_RAW, but it did not work. I know I’m being annoying, but is there anything I can do to debug this to make it work? Halp!? :slight_smile:


Could you try this to receive the raw payload with OMG (it wasn’t the MQTT length in my case but the raw buffer; the payload from my AC split unit is also 112 bits and only the first part of the message was read)?

Sorry for such late reply, but I had quite a week at work :frowning:
OMG! You are a genius! I just flashed the gateway with the suggested change and bam, I can see stuff in IRtoMQTT topic:


This is great! Apparently Haier is also 112 bits like in your case! Ok, now I need to think how to make it work with HA and how to actually send anything :smiley:

Ok, now that I finally getting some progress, I got some questions.

The lack of “raw” value is because I need to enable raw forwarding in config_IR.h, correct? Do I need it if I have “value”?

When I try to publish to
my gateway restarts and is unable to reconnect. I tried with the same message I got in IRtoMQTT topic but result is the same.

If I have Serial monitor open I see this:

Hey I got a callback
MQTTtoIR json
MQTTtoIR data || raw ok

Is this due lack of raw data?

Actually Florian figured it out in the first place (I just provided detailed info of the problem :slight_smile: ).

In order to publish the raw values for the unknown protocols such as those for AC units,
#define pubIRunknownPrtcl should be set to true in config_ir.h

To add support for the specific brand and not use the raw value, the payload should be decoded. Here’s what I managed to work on about two years ago when I’ve started using OMG (just a printscreen of the excel file, as it’s not advisable to open excel files from strangers on internet :slight_smile: ).

I started by writing down each command values from the remote and the code in hex. After splitting on individual blocks, several patterns emerge: first 10 chars are constant, field 11 is on/off indicator, 13 is for mode, etc.

In regard of the temperature field (15), the function in cell AC5 is as following:

The problem is that fields 27 and 28 are the result of checksum validation. Although I applied the same steps as for temperature (conversion to bin, replacing 1 with 0 and reversing), I didn’t got to the same result so I didn’t continued and just used raw values which was much easier in HA.

You have two options to set it in HA: as a switch (recording only IR for on at say 16 degrees and off commands), then a thermostat that controls it (see below; the payloads are huge and have only included parts) or (much more complex but uses all functions of the remote) as HVAC (however, this one needs all button combinations to be recorded as raw, which are in the range of hundreds; I have both set but after HA 0.96 the HVAC component is broken so the simple thermostat is better :smile: )

Thanks again! First I need to investigate the exception. Also I am getting sort-off proper value in the IRtoMQTT topic for my codes, just I was wandering about empty “raw:” part. Maybe despite getting the value I need to work with raws like you described, hm :thinking:

I flashed (not without issues) 0.9.2 today. I had troubles with changes to the libs (troubles like where are they :wink:), but managed in the end.

But to the point. It does not crash on send like before, so it seems the bug reported in other thread is fixed and that made it work for me as well.

Few notes though:

1.Gateway name changed (to home/OpenMQTTGateway_ESP8266_IR/IRtoMQTT in my case), got me confused at first but I found the correct one with MQTT.fx discovery
2.I am getting double messages.
One like:


The other just the value:


3.I don’t know why, but when I enable scan, instead of expected (I think :thinking:):


I am getting:


So the old gateway (it even reports as 0.9.1 in Version topic) and the new one. I have only one OMG so this does not make sense. All the subsequent topics found are from the correct version/base topic.

4.Still can’t send :frowning: But at least it does not crash.
When I publish to
I am getting:

Hey I got a callback
MQTTtoIR json
MQTTtoIR value || raw || datasring ok
Pub json into:
Pub data per topic
Hey I got a callback
Store str
Hey I got a callback
Store str
Min ind:

JSON str

I feel like I’m beating a dead horse with this one…

I’m not doing anything fancy…

  1. Downloaded CODE from releases
  2. Unpacked somewhere and opened it in PIO
  3. Build the project
  4. Uncommented default_envs = nodemcuv2-ir
  5. Made changes to IRrecv.h (kRawBuf up to 300 from 100)
  6. Put in my MQTT and WiFi settings and uploaded.

This Haier is really not playing nice with OMG…


For the point 1, yes there is an overload of the gateway name for each env. In your case with IR I put this name but feel free to change it.
For 2 this is due to the activation of simple publishing, since your post I removed it for all the env except the ones with all the modules that are for tests purposes.
For 3 you should delete the old messages with mqtt explorer or equivalent. Indeed they are retained by the broker.
For 4 I need to think on it more

And sorry if the last changes introduced with pio was disturbing.

For 1. Cool, I will take a look. I assume I change this line in platformio.ini

build_flags = 
  '-DGateway_Name="OpenMQTTGateway_ESP8266_IR"' <---

For 2. So User_config.h values are overwritten by platformio.ini? Because I have it disabled in code, but I see this:

lib_deps =
build_flags =

So I assume I change DsimplePublishing to false and we’re good?

For 3. Got it! Thanks, indeed I was able to remove the old topics from MQTT server using the explorer tool.

For 4. Ah, no rush. Sorry I’m causing so much trouble :wink:

PIO is great, but I think the change should be a bit more documented. I still managed to run it, it got all the libraries and all, but for someone that VS Code is not a daily editor this is a bit more complicated than Arduino Studio :wink: I still don’t know for example if I should update libraries like PIO is asking me all the time, I assume not, so I’m disregarding those notifications.

Still…great work :+1:

Good Sir, did you, by any chance, had time to take a look at the problem I reported?

Yes exactly

Not all but at least the ones in the example given (platformio.ini), I’m enabling step by step this overload capacity, if you have special request don’t hesitate to ask me.


I’m thinking on adding to a chapter on uploading with Arduino IDE

Thanks for answers but I mainly wanted to know if you had the chance to look at what I reported in earlier posts - Home Assistant and IR gateway problems

I’ve just made a big update (library and code) for irremote esp8266

Note that the protocol_name should be directly the protocol itself in capital letters like here

If you can test with it, I corrected some issues

Perfect, thank you! I will as soon as I get my back online. It decided to eat my memory card and I’m toasted at the moment. I will be moving it to Docker on the server I’m in the process of setting up. I’ll report back as soon as I can, thanks again for all your hard work @1technophile :vulcan_salute:

Actually…I now that I think about it I’m a dummy, I don’t need HA for that :slight_smile: I’ll try to test it by the end of the week cause I curious about the improvements I saw on Github :slight_smile:
