SerialTransfer VS IRremoteESP8266

If I were you, I just go with serial transfer. https://github.com/PowerBroker2/SerialTransfer This library provide data packet, header, CRC.

It is this library here and the tx/rx datum examples which are super basic

I found this: https://github.com/PowerBroker2/SerialTransfer/blob/master/examples/i2c_tx_data/i2c_tx_data.ino

My plan is to send the button and stick values over to Arduino with serial using SerialTransfer.

I am planning to do this soon(TM).

Probably starting with ESPHome to control my heat pumps over IR.

The remote works but I forget to turn it off when not in one of the rooms, and it can't do smarts like keeping temperatures in desired bounds.

An ESP32 running ESPHome with high power IR LED, a presence sensor, temperature sensor, and some pre-built library to control heat pumps[1]. it looks like it should be fairly simple to implement with Home assistant.

Now if I could only disable the beep from the heat pumps receiving commands.

I would like to do smarter lighting, but the lack of decent smart light switches that support local control and are also licenced for use in AU are a blocker there.

ThermTerm solves all the problems I've had with these physical controls, while integrating the heat pumps into Home Assistant via MQTT. Additional sensors pipe temperature, humidity and light data, for statistics and automation. Out of the box, ThermTerm supports Mitsubishi's infrared protocol, since that's the system I have. Thanks to integration with IRRemoteESP8266, you can make ThermTerm work with your own heat pumps by writing a few lines of adaptor code.

This library has the IR codes defined for tons of heat pumps. The only thing about node red is that it uses Java to build the UI on the webserver. If your already familiar with Java then no big deal, but it's just one more syntax to learn lol.

I used this library with a D1 mini. I then use this to put in my dashboard There are some examples one is a receiver code that you can get your codes, they also have a lot of ACs codes already. There is also an IRServer example that integrates with MQTT and has some stuff to put in your configuration.yaml so you can get it into HA easily I used this for 6 Samsung ACs, LG Dryer, some basic fans with IR. Samsung is the same each command is like all commands in one on, temp, etc. It has all this built in. I think if you have a IR receiver on your esp board and it will sometimes pick up the commands sent by the regular remote so if someone else uses the dumb remote it will update in HA. It's not perfect but it works pretty well. you can get all in one boards on ali express if you search iresp8255 they have transmitters and receivers.

I have tried https://github.com/Arduino-IRremote/Arduino-IRremote and https://github.com/crankyoldgit/IRremoteESP8266, both cause the same error.

First, try to remove the resistor(i was made an ir remote using the top circuit for ir sender). check the components, maybe one of them are dead. Second, check the gpio and config. Third, maybe the problem is the code. Maybe you should try the original IRRemoteESP8266 library first: You should checkout the original esp8266 ir remote library first: https://github.com/crankyoldgit/IRremoteESP8266 checkout my project: https://github.com/KD-MM2/MHI-AirCon-ESP8266/blob/main/Ver-1_Webserver_IRRemote/TurnOnMitsubishiHeavyAc.ino

I was able to finally read one of my remote codes that my other receiver couldn't with the flipper. I then used this library with a D1 mini.

My AC is fujitsu and I found library to control: https://github.com/crankyoldgit/IRremoteESP8266/blob/master/src/ir_Fujitsu.cpp

If it has a remote you can try to control it with an ESP32 with an extra infrared led. Check if it is supported by this library. Some coding would be needed.

I am using the this library and the irmqtt server example. But one thing I did was use a NPN Bipolar Transistors PN2222. I have one leg of the transistor on ground, one leg on a 220ohm resistor ( I think that's the one I used) to the D4 pin and then the ground of the ir led on the last leg then the + side of the led to the 5v side.
