OMG IR Gateway not working with AC

Theengs OpenMQTTGateway Infrared gateway
1

Hi @1technophile.

First, let me thank you for the amazing work already done :slight_smile:

I’ve been trying to setup my A/C unit using the IR_Gateway.
I have a Junkers (Bosch) Excellence AC. This is basically a Gree A/C, that equips many units out there.

I tried every thing already, and I cannot get it to work. I tried to use some demos from the IRRemote library and I manage to send the poweron and poweroff commands already, so I know my setup is working properly (NodeMCU + ir receiver + ir emitter + transistor + resistors).

This is what happens when I receive on the sensor.
Below the MQTT i receive for several AC inputs.

And here what i get on the log, for the last command:

Hello,

Thanks for this timely case, I was looking for some verification of IR gateway before releasing v0.9.3.

First are you using v0.9.3rc?

What do you want to achieve, i suppose controlling your AC with OMG but I see only logs on receiving and no attempts to post an MQTTtoIR command?

Hi

Thanks for the reply.
Yes, I’m using the current development version (from 2 days ago).

I was trying to get the RAW values and use them.

Nothing happens to my A/C if I try to send any of the received commands.

MQTT pub command

Log on arduino:

Thanks for the details;
Could you try sending the hex value instead of the decimal one

mosquitto_pub -t home/OpenMQTTMasterRoom/commands/MQTTtoIR -m {"datastring":"2,50,60,09,0B","protocol_name":"TECO"}

Pub command
mosquitto_pub -t home/OpenMQTTMasterRoom/commands/MQTTtoIR -m {"datastring":"2,50,60,09,0B","protocol_name":"TECO"}

I see activity on the led (using my phone). But nothing on the AC unit

Just some more info.
I’ve set #define pubIRunknownPrtcl true

Then I sent some random commands to the receiver.
Swtich ON, Mode Auto Cool, Mode Dry, Mode Vent, Mode Auto Heat, Mode Heat/Cool, Switch Off.
This is what i got on MQTT.

Tried to send some of them, nothing worked. Led illuminates :frowning:

There is something to do with the data string:
by checking what you receive and what is defined here maybe you could try that

{"datastring":"02,50,60,09,0B","protocol_name":"TECO"}

And replace datastring with the different values captured below as “hex”:

Still not working :frowning:

Endless road ?

You’ve tried with the 0 in front of the 2 ,
{“datastring”:“02,50,60,09,0B”,“protocol_name”:“TECO”}

And with different codes?

10

I have found an issue in the code, I will correct it and come back to this topic

@cinzas
I corrected it in development branch:

You can now use:
mosquitto_pub -t home/OpenMQTTGateway/commands/MQTTtoIR -m '{"hex":"0x25060090B","protocol_name":"TECO"}'

instead of datastring
