    Wasn’t there a post here a while back about how half the people here are only here because they were too toxic to be anywhere else? If I’m not remembering wrong, I feel like that post could be relevant.

    Anyway, I read the entry from the original post and it’s not entirely wrong, thought it definitely depends on the instance you use. Still, some of it is pretty damning for the concept as a whole. Hopefully some standard health/safety features become the norm.










  • Are you setting the multiplier value to the voltage? If so, that’s not correct. It’s not a literal value but a ratio.

    On my Heltec V3s, I have been fine with the default firmware values (they’re on the linked page below).

    ADC Multiplier Override

    Ratio of voltage divider for battery pin e.g. 3.20 (R1=100k, R2=220k)

    Overrides the ADC_MULTIPLIER defined in the firmware device variant file for battery voltage calculation.

    Should be set to floating point value between 2 and 6

    Calibration Process

    1. Install the rechargeable battery.
    2. Charge the battery until full. Indication of this state may vary depending on device. At this point, the battery voltage should be 4.2V ±1%.
    3. Input the “Battery Charge Percent” displayed on the screen or in your connected app into the calculator below.
    4. If “Battery Charge Percent” (e.g., B 3.82V 60%) is not displayed on the screen, it means that the default value of “Operative Adc Multiplier” is too high. Lower the “Operative Adc Multiplier” to a smaller number (it is recommended to decrease by 0.1) until the screen displays “Battery Charge Percent”. Enter the current “Operative Adc Multiplier” in use into the “Operative Adc Multiplier” field in the calculator. Also, input the “Battery Charge Percent” displayed on the screen into the calculator.
    5. Click the “Calculate” button to compute the “Calculated New Operative Adc Multiplier”, and set it as the new “Operative Adc Multiplier” for the device.

    The calculator is below that on the doc page: https://meshtastic.org/docs/configuration/radio/power/
