Open source ESPHome IR blaster?

ESPHome
42

I like how that sounds, but tbh I’m not able to read thorugh that code and really understand it yet.

Is it something like this?
If remote_learn_switch is on (done using a button?),
then take the IR command (that starts with "Pronto: Data = ") from the log and put it in learned_command?
publish_state is new to me, maybe something like ‘save and make available’?
I’ve got some reading to do :smile:

and thanks… I don’t want to trample all over this thread with me getting my head around things though, better in the one I started while getting mine going?

Hey All,

I found a simple schematic online for a IR blaster.
I made a simple kicad drawing for it:

Dont mind the fan header :rofl: that is supposed to be the IR reciever.

The schematic:

It is based on a wemos D1 mini (this way I dont have to design the usb and such). And it can be soldered closer to the PCB for a flatter design.

If any one is interested i could put the project somewhere on GIT :slight_smile:

Just food for thought.

I use those cheap ($5 CAD) aliexpress tuya Wi-Fi based IR emitters that use the Beken microcontrollers and flash it with OpenBeken. They work very well and communicate using MQTT. OpenBeken works very well with HASS, the only downside is having to flash the chip which requires disassembly and soldering (or fly leads).

Might be 5 bucks, But where is the fun in that :wink:
Also MQTT is nice, but it is yet another item in the chain.

This is just esp home - > IR Might be 10 bucks, maybe 20.

But I get to do it myself and point all the IR leds in the direction i need (from the couch to TV straight ahead :slight_smile: )

Cheap aliexpress is not always the answer

Neither is reinventing the wheel.

That’s fair, I was just putting info out there for thought. Injection molded cases go a long way these days. I have a plethora of esp based ‘thingies’ everywhere, some are bare some have 3d printed cases. Sometimes it’s just easier to repurpose what others have already laid down the work for.

All that said, I also enjoy building things for the sake of building them, so I understand your train of thought.

You can also control the Kincony KC868-AG without using ESPHome using RESTful Commands. You can apparently use MQTT also, but this is easier. Regardless I’m probably going to have to use ESPHome according to the docs due to the different RF commands because it only supports 2 EF protocols but the raw data can be used. They also have some device/brand automations for learning IR/RF.

Hi All,

I have made my own IR blasterV2. It has a range of about 5 meters now.

As you can see there is still one design flaw on my pcb, but not too bad.

It has 3 resistors (1k and 47 ohm) 1 transistor bc337, and a ir reciever

Happy to share a gerber folder if you want to order one yourself :slight_smile:

Maybe the documentation explains this but, I havnt looked at it. What is the benefit of using multiple IR led"s?

It makes sense to me that increasing voltage/current close to the led max, that will increase IR range for sure but, how does just adding more led’s make it better especially when they’re all facing the same direction?

I could also see the benefits of putting IR led’s all around the circumference so it transmits 360 degrees but, whats it doing by having them all on one side and facing the same direction?

Its for my specific use case, and it works perfect. My TV is picky about the IR angle, and i point 3 straight at the soundbar and 3 straight at the TV ad a different angle but still pointing forwards :slight_smile:

Its an easy design and with 6 leds you could adapt it to make something like this:

Now you can point them all at a different direction. its opensource, do with it as you please :slight_smile:

Oh, I see. That makes sense if its for a specific use. Did you not want to add or need RF too?

I was thinking about doing both if i make one because some devices use IR and others RF. Having both in a single box sounds like a good plan to me.

The simplest way to add RF or any other extra item is with the grove cable:

the m5 stack eco system is vast, you can add so many i2c devices behind it :slight_smile:

But if you must want it to be in a all in one package you can design the board in a manner that it accepts this:

then its a all in one package :slight_smile:

I already use several rf transmitter/receivers. I actually prefer rf way more than I do IR. It seems like the range is far better and there doesn’t need to be line of sight and there’s less signal loss from walls and obstructions that you get from IR.

Other than common transmitter and receivers, I’ve become very fond of these 4 way transmitters. They’re super easy to use and the range is very good.

About?
Does receiver have raw non decoded output?

I havnt checked actually. At the moment, im only using 1 of the sets I have and I use them to open/close a group of solenoids.

Hi, @Fallingaway24. I have RF ceiling fans I’m looking to automate. You mentioned you use RF receiver/transmitter, would you have a write or resource on how this can be done?
