how to playback IR (irsend)

Post by czosnekno1 » Wednesday 04 April 2018 13:49

Hello
Using the example sketch from the https://www.mysensors.org/build/ir


, I managed to program a few pilot buttons in the domotic. (IR codes are of course entered in the section: IRCode PresetIRCodes [] = (...).
I would, however, "upload" a few IR codes to Domoticz, which would control my TV and AV via the IR diode from the Domoticz level.

In this example, there is the sendRCCode () function, which, in theory, sends an IR code (previously uploaded to Domoticz) via IR diode, if of course it will get
message.type == V_IR_SEND.

I added in arduino sketch an additional declaration:MyMessage msgIrSend (CHILD_ID, V_IR_SEND);

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

 *******************************
 *
 * REVISION HISTORY
 * Version 1.0 - Changed for MySensors usage by Bart Eversdijk
 * Version 1.1 - Added option to record manual presets up to 240
 * Version 2.0 - Migrated to MySensrors version 2.0
 * 
 * DESCRIPTION
 *
 * IRrecord: record and play back IR signals as a minimal 
 * An IR detector/demodulator must be connected to the input RECV_PIN.
 * An IR LED must be connected to the output PWM pin 3.
 *
 *
 * The logic is:
 * If a V_IR_RECORD is received the node enters in record mode and once a valid IR message has been received 
 * it is stored in EEPROM. The first byte of the V_IR_RECORD message will be used as preset ID 
 * 
 * If a V_IR_SEND the IR message beloning to the preset number of the first message byte is broadcasted

}
but in Domoticz there was no additional Device that would be responsible for sending IR codes.There is only one children: V_IR_RECEIVE.
I think I probably need to do an additional Dummy Switch, which will send an IR signal transmission command to the gateway / node using JSON.
I'm thinking about it for a long time and I have no idea how to do it in DOMOTICZ.
Please help me how to do it.

Re: how to playback IR (irsend)

Post by lamptah » Monday 15 October 2018 5:30

Hello, not sure if you are still looking, but if anyone else comes across this ...

There was a bug in domoticz that prevented the sending of any codes via V_IR_SEND. That is fixed in the latest beta, (commit https://github.com/domoticz/domoticz/co ... 4dcc1543b3). With this fix, any code that was first received by domoticz (and created in the hardware) can now be sent back again by activating the switch that was created. This will play back the exact code received, in your screenshot code 26. It is handled by the same child that manages V_IR_RECEIVE.
