Great catch! I haven't looked at it from that angle.
However, I'm using escape sequences like the one above to include parts (2 to 32 bytes) of a binary protocol . They are sent out on the serial interface.
Replacing all printable characters in the sequence would be cumbersome and error prone. Can such warnings be disabled?

Will the firmware update of Espruino Pico utilise the USB DFU function of the ROM Bootloader?
I noticed that the build environment is using http://dfu-util.sourceforge.net but im curious if the DFU function is only intended for the development phase? -

@Gordon most sensors measure temperature and humidity (the accuracy of the humidity sensor is however debatable)
@MetallixBrother Yes range is a problem... if you still have to apply additional nodes as repeaters the advantage of using prebuilt temperature and humidity transmiters is little.
Sidenote:
I tried two different receivers in for my project, the cheap MX-05V

Have you considered buying Oregon Scientific or similar transmitters and just implementing the receiver on the Raspberry Pi?
Receiver Library is available on GitHub https://github.com/daveblackuk/RPI_Oregan
Just be careful not all transmitters use the same protocoll. -

According to http://www.espruino.com/Clocks the Watch Crystal will automatically be detected and used.
I don't have an oscilloscope or a frequency counter.
Is there any way to verify that the Espruino did indeed switch to the crystal like a function that prints the status?
The alternative forms look nice! Thank your for the suggestion.
