Linux command to read Temperature Sensor(s)
Hi,
I would like to turn a kobo touch into a weather station. I would love to display the actual room temperature. Is there a linux command to read the actual cpu or battery temperature of the kobo touch? thanks a lot in advance! |

Not sure about the Kobo Touch.
The Kobo H2O has a MAX17135 sensor. Or at least, that's the only sensor driver enabled in the kernel. Quote:
There actually is a /sys/devices/platform/mxc_epdc_fb/graphics/fb0/temperature and it says 23 for me which happened to be the room temperature... but I just put it out in the cold and it still says 23 so... maybe something else after all. lm-sensors doesn't find anything. PS: it did go down to 22 while writing this post. |

Thank you for your reply!
is it possible to search for *temp* in /sys/devices ? I hopefully get the kobo touch at the weekend, then I see for myself |

find /proc /sys -iname "*temp*" is what I did (same for therm) and that's what I found on the H2O...
As a weather station you have to get weather info from somewhere too, so maybe you could acquire temperature from one of your other devices this way too. Good luck. |

Hi,
thanks again for your input! I rooted my kobo touch and with this command i can read the temperature sensor: cat /sys/devices/platform/tps6518x_sensor.0/temp_input This command gives me "21". I assume this is the correct temperature reading. |

Scusami, but i found for Glo
This path only for Touch? I looked Glo hardware, also used TPS65185. But i not find like /sys/devices/platform/tps6518x in Glo. I am looking for a way to read and write value VCOM. Also for Touch |
