fujihk's Issues

Can I contribute the design of a small PCB that serves as a shield for the M5Atom Lite?

I have designed and produced a PCB specifically for this project following your schematic, if you like I can pass you the Gerber and BOM.

Let me know, anytime!

Hello.
Hello, I have a compilation problem.

I have this error:

C: \ Users \ Dell \ Documents \ Arduino \ fuji-hk \ fuji-hk.ino: In function 'void homeSpanEventHandler (int32_t)':
fuji-hk: 491: 10: error: 'HOMESPAN_WIFI_CONNECTING' was not declared in this scope

Do you know how to solve the problem?

Maybe you have a compiled version.
Is it possible to share?

bin File does not work at all

Hi, I flashed the .bin via NodeMCU PyFlasher, the procedure seems to have been successful.

I disconnect and reconnect the Atom but when I try to run the procedure to start the SoftAP for pairing, the led doesn't flash and I don't see any AP to connect to.

So I thought I'd see from the serial monitor what was going on and that's what the Atom repeatedly spits out:

Sorry, newbie here … a few basic questions

I apologize if it’s not correct protocol for even posting such questions under ‘issues’. I was excited to see this project but it will push my lack of skills around coding and even basic electronics to the limit. Before I even attempt any of it (even though I have purchased the basic components already, LOL) can anyone let me know whether it will work with my setup? I have a Fujitsu 208737 heat pump. It already has an a WLAN adapter which works with FGLair app on iOS. The step that is of greatest concern to me is ‘Connect the M5Atom to the AirConditioner via the 3-wire interface (see example circuit) or via the com connector on the indoor unit (will need a logic level converter)‘. Any clarification around that (assuming that it’s even applicable to my setup) would be appreciated.

Unable to add accessory, the setup code is incorrect

Hi, I have configured everything as per your instructions but, I have changed the configuration code and checked that the terminal returns the correct code I entered.
When I try to do the procedure to add the accessory, both iPhone and iPad (iOS 16 and iOS 15.7 respectively) return the error "Unable to add accessory, the setup code is incorrect" and the terminal tells me "SRP Proof Verification Failed".

Am I doing something wrong? Can you help me out?

Nearly working - commands not reaching controller

Hi - thanks for the amazing project, I wonder if you would mind advising me on where to go from here please?

I have a Lolin D32 esp board with LIN transciever and buck regulator as usual but most importantly, this exact hardware works with the derived project https://github.com/FujiHeatPump/esphome-fujitsu. All i did to try out the native homekit solution from this project is re-flash it, I didn't change any connections.

I want to try native Homekit now, so with your fine project, all I changed is in the Arduino IDE the board of course, and the serial port pins for my already built hardware:

#define RX_PIN 16 (RXD2)
#define TX_PIN 17 (TXD2)

NOTE I do not have a neopixel connected in case that's important.

I can pair the unit in homekit (actually took a few attempts, probably not related), but get no control or status, continually get "no response". HVAC continues to work fine on the wall panel/remote, no errors or anything.

Would you mind looking at the logs below and any advice on how to troubleshoot?

Maybe it is to do with "UNSUPPORTED MODE IN convertACModeToHKMode 0! RETURNING 0" ?

I have triple checked that my LIN chip RX pin is connected to GPIO16 and TX to GPIO17 as it seems everything works but it's not communicating to the Fujitsu remote. Could the pins be updated elsewhere or do the logs tell you something different is the issue....?

I believe that the lines "update(): coolingThresholdTemperature -> using midpoint 21C instead" show the commands i am trying to give from Home app are getting to the device, but it's not communicating to the HVAC. I could be on totally the wrong path though :-)

Everything has been power cycled many times. The esp board is powered via regulator from the remote's 12V line.

It must be something simple, it's the same schematic as shown on your pages, with only a difference in serial port pins.
