Test if running on real device?

Is it possible to test whether an app is running in the IDE or on a real device (Bangle 2)? For example, E.getBattery() always returns zero in the IDE so it's hard to check if a low charge warning is needed. Thanks and sorry if I'm missing something obvious!

maybe there is better version but check output of process.env

>process.env
={
  VERSION: "2v16.1",
  GIT_COMMIT: "1a18b5384",
  BOARD: "EMSCRIPTEN2",
  RAM: 0, FLASH: 8388608, SPIFLASH: 8388608, HWVERSION: 2, STORAGE: 8388608,
  SERIAL: "00000000-addeadde-addeadde",
  CONSOLE: "USB",
  MODULES: "Flash,Storage,hea" ... "tensorflow,locale",
  EXPTR: 155840 }
> `

so you may test process.env.BOARD or the SERIAL

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here
```
Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
