Nearly working - commands not reaching controller #6

Closed YouCanNotBeSerious closed 9 months ago

YouCanNotBeSerious commented 10 months ago

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.

A good start would be to add hp.debugPrint = true; just after the hp object connects: https://github.com/unreality/FujiHK/blob/3856c17ebb1a7e9938d94b8faac02dd32d44f5cd/src/fuji-hk.cpp#L410

It should print out the frames it sees on the bus. If you dont see any coming in, then your rx/tx lines might be mixed up, or the LIN controller not working correctly...

YouCanNotBeSerious commented 10 months ago

Thank you, I am trying that now... could it be related that i have trouble adding the accessory to home every time, it takes a long time and multiple attempts. Also noted the serial debug terminal stops responding after maybe 30 sec - I have time after flashing to set my wifi, then it stops unless i reboot the board. The debug frames below never stop though so maybe the setup terminal is only active on startup by design.

OK some more - the debug info above corresponds and updates with my actions on the remote control panel - here i turned it on, changed the temp to 30 - and it seesm to be commuicating. Very cool!

So comms seems to be OK - but please note it still takes many atempts and a long time to add the accessory to Home. This is probably more of a pointer to the problem now....

Focussing on my hardware differences, i am using a Lolin D32 board, I don't have the neopixel connected, and i don;t have a pushbutton connected. Could there be any dependancies there? I also am still having trouble adding the accessory to Home, it eventually worked but since flashing the debug frame line above i can;t add it - am going to remove that ine since it seems to have shown the issue is not comms with the fujitsu unit.

Is it expected that the serial terminal stops responding after about 30 sec on boot btw? I have to be quick to get my wifi settings done....

OK - I have progress.

I think it is some kind of lockup or crash issue.

What I have proven over at least 2 dozen attempts is that the serial debug comms stops after as little as <30s when i am using the debug tools i.e. set wifi, pairing code, or as long as a couple of minutes when watching the LIN frame info stream past. Also this is why i have had trouble adding the accessory to my Home - if i do it quickly after boot it works fine, if i am too slow the process starts but then times out after the board stops responding.

I did in fact catch the Home app communicating with the esp as shown below, but then the comms stopped - suspected board lockup. Serial comms only comes back if I reset the board,

Any ideas? Surely it has to be an Atom --> My D32 board difference....? I am compliing in the latest released Arduino IDE, no errors, selecting the D32 board in the IDE...

The Atom seems to use ESP32-PICO-D4 and my board uses ESP32-WROOM

Noted that if I press "W" in the serial terminal and scan for available wifi, then do not enter anything, it stays responsive for many minutes where normally it stops responding.... maybe that points to which area of code is in play.

SOLVED!

As usual when troubleshooting these things, I feel a bit silly now, but will leave this issue here so others might benefit.

The “button” pin in the code happenned to map to a TOUCH sensor input on the dev board i used! Naturally this pin had to be one that was unconnected ;-)

A floating input is never wise, but a sensitive touch sensor input..... well, it resulted in this issue and has been solved with a simple 10k pullup resistor.

If I had implemented the button this would never have come up, but the dev board is hidden behind the drywall behind the Fujitsu wall remote so I saw no need for a button.

ALWAYS check the basics.....

Maybe I redeem myself slightly if I mention that this all works fine with MCP2021-330 for the LIN transciever which was easier to source for me....

Thank you for your help @unreality and more so thanks for this fantastic project. My Fujitsu ducted whole house HVAC now has a new lease on life, automations will be coming out my ears to turn it off when no one is home, preheat/cool the house on a schedule and all sorts of things.

Proven working fine more than a month later, check and doublecheck your hardware definitions is the lesson I learned :-)
