Climate IR driver for the Daikin BRCxxxx remotes?

Coenenp · August 13, 2022, 4:02pm

The refresh did the trick. Now getting correct values.

hagak · August 13, 2022, 4:23pm

Awesome let me know if you have any other issues. I need to clean up that repo before I do a PR. Was not familiar with how esphome is tested and was do tons of small commits. Want to refactor into a single commit.

Coenenp · August 13, 2022, 5:39pm

Thanks a lot! It’s working really nice for ‘Cool’ now. I did notice however that for dry and fan mode the temperature sets to 45C. I don’t use dry and fan modes anyway and on my remote there’s no temperature for those modes. Although the default temperature for those modes is 17C.

What actually bothers me most is that it should remember my temperature when I go back to Cool mode. Even though my remote uses 17C in dry and fan mode, it remembers the temperature for cool. I’ll probably try to solve that in home assistant.

hagak · August 13, 2022, 9:15pm

Yeah behind the scenes the system sets the temp to a preset temp when you change modes to DRY and FAN. The protocol requires you set the temp. fields so it should be 17C for you but I missed that when i made the changes. I will correct it but probably not until tomorrow.

Now then I do know about the issue with maintaining the last set value when changing modes and that is still an issue, not sure any of the climate ir modules handle this, but I would like to come up with a way to deal with it in the esp itself. Probably could have a an event on mode change store the current value and restore when the mode changes back. But would need to make sure you are not also setting the value when changing modes cause that would be annoying.

hagak · August 15, 2022, 12:54pm

Just updated the FAN/DRY mode to properly set the C temp. to 17C.

Coenenp · August 16, 2022, 12:05pm

Thanks, I’ll update my IR devices tomorrow.

Note I just submitted a pull request for this change into esphome.

Really appreciate this work! Hoping someone can help me troubleshoot: I have a newer Daikin mini-split with a BRC52B61 (or 62/63/64) remote and the external components from @hagak repo. Using esphome and an esp32 with a 940nm transmitter bulb, TSOP38238 receiver, and a dht11. I also installed a 2n2222 transistor to boost power to the bulb.

I’ve verified it is transmitting - I have an older Pixel phone without an IR filter so I can see the bulb blink. My receiver also picks up the codes when I transmit which I can see in the logs. However the Daikin unit won’t react to any command. I’ve even held the bulb right next to the receiver on the indoor cassette with no change. Is it possible there are different codes for this model even though it is also a BRC? Anything I can provide to help troubleshoot?

hagak · October 2, 2022, 8:51pm

First off is your unit on Channel 1? The BRC default to that and if you or the installer did not change it, i would expect it to be on that channel. The code I wrote only works on Ch 1 since that is all I have.

Also make sure the ESP32 is not rebooting due to a brown out. I ran into this issue due to trying to use a USB cable to power it that was long and getting a pretty hefty voltage drop that when the IR LEDs are activated it would cause the voltage to drop below spec for the ESP32 and it would reboot.

Lastly I have a BRC4C163 (US model) and I found one other person who had another model that worked in C. Discovered that the models are hard coded to work in either F or C and they actually change the temp. encoding based on this. Wonder if your model has some other encoding issue that is off. When you do received signals from your remote is the info printed out in the logs match with what you expect?

planetix · October 2, 2022, 11:29pm

It’s on channel 1, yes.

I don’t believe the ESP32 has a power problem as I’m watching the logs in ESPHome while transmitting and there’s no indication it’s gone offline or otherwise restarted but if there’s something I should look for I will try it again.

When I use the BRC remote my receiver picks up Pronto-format codes that look similar but would it help if I collected some for you? Tell me what commands to try and I’ll paste the output for both the remote and what I get when I use the ESPHome emitter.

planetix · October 3, 2022, 5:57pm

@hagak Here’s the log output, I can’t claim to know enough about IR hex to understand if it is a problem, but the output captured when I trigger the ESP (via Home Assistant’s climate/thermo) to turn the unit on/off or set to cool is different than the output my receiver picks up from the BRC remote. Anything useful here?

The pronto codes are not all that useful for me.

BUT when you use the IR Remote and the Esphome receives the signal, does the output in the logs “Fan Speed, Target Temp, Mode” match what you send with the remote?

planetix · October 3, 2022, 6:53pm

Ah, got it. No, what you see above is all I get when I use the BRC remote, the raw/pronto codes. The climate component doesn’t react.

hagak · October 3, 2022, 7:04pm

you get the data, but does the data match what you send. I can not tell you because I do not know what you are pressing on the remote.

No climate message sending state, etc.

Ok so it does not even understand the data coming in. So looks like the protocol is pretty different. Would be hard for me to debug/fix without the hardware.

Shoot. Are you in the US? I’d be willing to send you my remote to test with if it by itself would be helpful?

If you have a rpi you could do the reverse eng. work.

If you can get that info I might be able to update the code base.

planetix · October 3, 2022, 8:04pm

I will take a look, I have some Pi’s and other related gear laying around. Are you looking for the output from decode.c?

hagak · October 3, 2022, 9:51pm

yes the output of that. You have to keep ALL settings the same and have an output for each change with notes of what changed. I also need atleast 2 entires for temp. changes. And each of the fan speeds.
