Unable to Send IR Signal

Gateways Infrared gateway
#1

Hello,

I’m using OMG with only ZGatewayIR. I have tried both master & development branch.
I’m using default pinout on ESP8266.

RX is OK.
TX doesn’t work.

I have tried IRSendDemo for my Sony TV to Power ON & OFF, it works with D0/PIN16.
With OMG I have replace with a normal LED. I see the blinking while sending…

FYI, the message format on repeatIRwMQTT is wrong :

home/OpenMQTTGateway/commands/MQTTtoIR 1587664935

must be :

home/OpenMQTTGateway/commands/MQTTtoIR '{"value":1587664935}'

I have tried to send Raw signal, but it still doesn’t work. MQTT message is at 1024.

I don’t understand why it fails.

Here is an example of my serial output :

Using NEC protocol
MQTTtoIR OK
Pub json into:
home/OpenMQTTGateway/IRtoMQTT
{"value":4294967295}
Hey I got a callback

thanks for the help.

PS : OMG in développement branch reboots while using protocol IR_Sony.

Sorry to hijack this thread but I have a similar problem as well with my wemos D1 mini and Lolin IR shield. I do not seam to receive any IR signals looking at mqtt explorer.
I can see in mqtt explorer, the gateway topics of LWT and Version only for OpenMqttGateway.

what am I missing or doing wrong?

Hello,

You should add the protocol to the payload, it should be IR_SONY

I was receiving 2 messages on RX. First one was incomplete, so value was wrong. it works great with the 2nd message. I ran a IR receptor on Arduino to compare signal between remote and esp8266 to understand.

Could you post for the others an example of working messages please?

Hi,
I saw this post while trying to understand why my Sony TV did not receive IR signals which seemed to be correct:
mosquitto_pub -t home/OpenMQTTGateway/commands/MQTTtoIR -m '{"hex":"0xA90","protocol_name":"SONY"}'

By reading the code, I understood that “Sony devices expect the message to be sent at least 3 times.” Now, that works:

mosquitto_pub -t home/OpenMQTTGateway/commands/MQTTtoIR -m '{"hex":"0xA90","protocol_name":"SONY", repeat:3}'

It might be a good idea to add this in the doc or, maybe to automize sending 3 messages when protocol_name is SONY?

Thanks

Hi,

Thanks for pointing that I will automate it
