External regression - Si1145 Project doesn't compile anymore

[Lefuneste83]

The problem

I have noticed that I cannot compile my weather station project anymore. It has been working for years but probably due to a change in the libraries dependencies, it refuses to compile anymore, It seems to miss one library since I last updated Esphome.

/data/weather/.piolibdeps/weather/Adafruit SI1145 Library/Adafruit_SI1145.h:25:32: fatal error: Adafruit_I2CDevice.h: No such file or directory

I have tried to force previous versions of the Adafruit SI1145 Library but with no success. If I place this library Adafruit_I2CDevice.h by hand in the /config/esphome directory, it then complains about Wire.h missing.

I think something has changed with the Adafruit SI1145 Library as it now installs the Adafruit BusIO as a dependency which I believe was not the case.

If anyone has some idea on how to solve this as it seems a widespread issue with the Adafruit BusIO Library.

Which version of ESPHome has the issue?

v2021.12.0-dev

What type of installation are you using?

Home Assistant Add-on

Which version of Home Assistant has the issue?

core-2021.11.5

What platform are you using?

ESP8266

Board

D1 Mini

Component causing the issue

SI1145, I2C, Wire

I have tried both

• adafruit/Adafruit BusIO @ 1.9.6
• mertmechanic/Adafruit BusIO @ 1.7.3

Without any change is the error. Also trided various versions of it.

Note that the Adafruit_I2CDevice.h file is present in the ESPhome container under the Adafruit BusIO directory, while at compilation time it complains that it is not found under the Adafruit SI1145 Library directory. I have tried to manually put it there with the associated cpp file, but it then complains about Wire.h missing.

[raphis]

I assume that this might be an issue affecting multiple libraries - in my case it's missing SPI.h and EEPROM.h

.piolibdeps/d1mini-somfy-wireless/SmartRC-CC1101-Driver-Lib/ELECHOUSE_CC1101_SRC_DRV.cpp:16:17: fatal error: SPI.h: No such file or directory

.piolibdeps/d1mini-somfy-wireless/Somfy_Remote_Lib/src/EEPROMRollingCodeStorage.h:4:20: fatal error: EEPROM.h: No such file or directory

I see this starting in 2021.11.1 running in docker - if I go one version back compilation works again.

[Lefuneste83]

This is interesting. So the regression would be linked to HA...

[oxan]

We turned off the PlatformIO LDF in 1.11, so libraries need to be explicitly specified now.

I have tried both

• adafruit/Adafruit BusIO @ 1.9.6

Did you add this one to the libraries key, before the SI1145 library? I should expect that to solve the problem.

I assume that this might be an issue affecting multiple libraries - in my case it's missing SPI.h and EEPROM.h

Try adding SPI and EEPROM to the libraries key.

[Lefuneste83]

Compile issue is solved with the following additions

includes:
   - SI1145.h

 libraries:
   - SPI
   - Wire
   - adafruit/Adafruit BusIO @ 1.9.6
   - "Adafruit SI1145 Library"

Unfortunately after deploying the new firmware, the ESP8266 stays in a stale state and does not act as expected. the ESP LED Flashes several times when booting, where it should flash only once. I am still able to reboot it manually and push a new FW version meaning it is not totally dead as it is able to connect to Wifi and receive FW upgrade.

After commenting all sections about SI1145 (includes, libraries, plaform custom & sensors), recompile, and push the FW, the behavior is as expected.

So there is some form of regression in focing the SPI and Wire libraries. Maybe this has to do with the default I2C Frequency as I recall we had some issues with this when we initialy adapted the SI1145 to ESPHOME 2 years ago.

If anyone has former experience with this kind of behaviour let me know.

[Lefuneste83]

I believe this has to do with my custom library which does not interact properly anymore with the other ones

#include "esphome.h"
#include "Adafruit_SI1145.h"

using namespace esphome;

class SI1145_sensor : public PollingComponent {
 public:

  Adafruit_SI1145 uv = Adafruit_SI1145();

  sensor::Sensor *visible_sensor = new sensor::Sensor();
  sensor::Sensor *ir_sensor = new sensor::Sensor();
  sensor::Sensor *uvindex_sensor = new sensor::Sensor();

  SI1145_sensor() : PollingComponent(1000) { }

float visible;
float irlight;
float uvindex;

  void setup() override {
    uv.reset();
    uv.begin();
  }

  void update() override {
    visible = uv.readVisible();
    visible_sensor->publish_state(visible);

    irlight = uv.readIR();
    ir_sensor->publish_state(irlight);

    uvindex = uv.readUV();
    uvindex_sensor->publish_state(uvindex / 100.0);
  }
};

Ok I have rewritten the custom library carefully following the instructions from the custom sensor components and it compiles and seems to work now. I have also rearranged the variable declaration and calls so that they match the order of the Adafruit Library (doubt this has any effect). I have removed the reset call that was necessary before and did some other minor changes. Hope it's good now... Will see how it stands in the next couple of hours.

#include "esphome.h"
#include "Adafruit_SI1145.h"

using namespace esphome;

class SI1145_sensor : public PollingComponent {
 public:

  Adafruit_SI1145 uv;

  Sensor *uvindex_sensor = new Sensor();
  Sensor *ir_sensor = new Sensor();
  Sensor *visible_sensor = new Sensor();
  
  SI1145_sensor() : PollingComponent(2000) { }

  void setup() override {
    uv.begin();
  }

  void update() override {
    float uvindex = uv.readUV();
    uvindex_sensor->publish_state(uvindex / 100.0);

    float irlight = uv.readIR();
    ir_sensor->publish_state(irlight);
    
    float visible = uv.readVisible();
    visible_sensor->publish_state(visible);
  }
};

libraries:

• SPI
• Wire

Indeed - the problem was the order of the libraries - after I put SPI + EEPROM to the top it's working with the latest esphome as well. Thanks for the pointer.
