Heat pump monitor ESP8266 problem

Et0:

I haven’t manually entered network addresses since about 2002! But OK I’ve just tried that and it did not work

How did you do it? what subnet mask and gateway?

borpin:

The solution is to force the device you are using to an IP say 192.168.4.2

Et0:

I’ve just tried that and it did not work

If a phone did you disable mobile data?

Et0 · 2019-10-08T16:32:03.039Z

subnet mask 255.255.255.0 and gateway 192.168.4.1
All guesswork of course!

Yes, mobile data turned off on the phone, I saw that advice in the instructions (although I am on iPhone not Android).

Thanks

Et0:

compiled the 8266 firmware

Did you do this with PlatformIO or Arduino?

Et0 · 2019-10-08T16:37:22.495Z

Arduino.

@glyn.hudson Can you help?

I did read that as well. Mine doesn’t look like it’s crashing (not resetting anyway). But in any case I don’t know what espressif8266@1.8.0 is or where it lives - it’s not in the library manager or referenced in any source file as far as I can see.

Me neither .

Thinking about buying a pre-flashed ESP board, de-soldering the module and fitting it to the heat pump monitor board.

According to this thread: ESP continually resetting. Any ideas? - #15 by danbates - the “correct” esp8266 board package to use with Arduino is version 2.4.2. I was using the latest, which is 2.5.2, so I downgraded it. This now doesn’t build, lots of errors as below.

Hi Evan,
This guide needs updating to make clear the pio method isn’t working at the moment with master branch.

If you’re compiling emonESP master branch use Arduino with ESP 2.4.2 installed from the board manager.
If it’s the timer branch you’re using with the hp monitor then compile with pio.

I’ve never seen those errors before! Looks like a windows thing. Which version of Arduino is it? Might be worth trying to uninstall and install again the IDE or the ESP board package.

If using Arduino there are a few libraries to download also. Have you tracked them down?

The 1.8.0 thing referenced above is just PIO’s version scheme for the esp core, it actually uses ESP core 2.4.2 within it. If you’re compiling master using pio and espressif8266@1.8.0 is used, it should theoretically work the same as arduino compiling with esp8266 2.4.2 from the board manager.

Hi Dan thanks for the help.

This guide needs updating to make clear the pio method isn’t working at the moment with master branch.

OK, I’m not, but I volunteer to edit the instructions to say that, if (and it’s a big if) I ever get this working!

I’ve re-installed Arduino, bringing it up to the latest version, 1.8.9. I’ve also removed/reinstalled the ESP board package to 2.4.2. Same weird errors. If I change the board package to 2.5.2 it DOES compile but obviously still doesn’t work. Changing back to 2.4.2: errors.

I am using the emonESP main branch, from a couple of days ago.
I did search for and install various libraries, I can see ESP_Async_E1.31, ESPAsyncTCP-master, ESPAsyncWebServer-master and PubSubClient in the libraries directory. I think were some others found via the library manager.

danbates · 2019-10-10T22:22:10.993Z

Not sure what ESP_Async_E1.31 is doing there but eveything else looks fine.
How about flashing pre-compiled binaries?
Or do you want to change the code?

Et0 · 2019-10-10T22:27:23.137Z

The guide does not mention pre-compiled binaries, and I can’t see any binaries in the github…

danbates · 2019-10-10T22:54:22.245Z

That’s definitely something that needs updating in that case.

Flashed to the device with esptool.py with command:

esptool.py --baud 460800 write_flash 0x0 ./bin1.bin 0x300000 ./bin2.bin

Dan

Are the binaries master or timer branch?
They may need explicitly identifying.

Ian`

danbates · 2019-10-11T15:15:17.000Z

I’ve put master in master. I haven’t checked timer as I thought the binaries were already there.

Et0 · 2019-10-11T16:47:53.941Z

Dan, thank you VERY much, that worked (esptool.py write_flash 0x0 src.ino.bin 0x300000 src.spiffs.bin)

So, is it worth updating the guide to instruct loading these pre-built binaries?

If I understand right neither of the two options described to build the source are usable at this time - platformio per your comment above, and also this issue I just noticed on GitHub: “Compile error with Arduino IDE #66” - this is the same thing I am getting.

danbates · 2019-10-12T10:55:01.010Z

Noticed, thanks. I’ve updated the guide so am waiting for the PR to be accepted, just need to confirm with Glyn.
ArduinoIDE 1.8.9 I’m using on a Mac.
