Oh! Thank you so much! That would have been a nightmare to debug (I hope you didn't have to debug for too long... My mistake)

from esphome-core.

It wasn't "fun" to debug, in the end I used my Logic Analyzer and hooked it up to see what was going on :)
But don't worry, thanks a lot for esphomelib!

Oh noes... Sorry about that.

As a tip, you can set the debug level to VERY_VERBOSE and you will see the entire i2c traffic in the logs 😉 https://esphomelib.com/esphomeyaml/components/logger.html

Sorry for replying to this closed ticket, but I'm trying to debug an issue with TSL2561, and wanted to set the logging level as you suggested:

#define ESPHOMELIB_LOG_LEVEL ESPHOMELIB_LOG_LEVEL_VERY_VERBOSE
#include <esphomelib.h>
// [...]
    auto *log = App.init_log(230400);
    log->set_global_log_level(ESPHOMELIB_LOG_LEVEL_VERY_VERBOSE);

but I don't get any additional log entries :(

from esphome-core.

That would be because #define before an include only works with header-only libraries :)

So to set the log level to very verbose you need to set it inside platformio.ini:

[env:YOUR_ENV]
build_flags = -DESPHOMELIB_LOG_LEVEL=ESPHOMELIB_LOG_LEVEL_VERY_VERBOSE

Do you know an easy way to do this using Arduino?

from esphome-core.

Puh... that might be difficult. I've never really used the Arduino IDE before, but maybe this could help?

I decided to simply cheat, by modifying log.h :)
