That's good to hear, you power readings were very similar to mine. I pessimistically rounded up when the values were fluctuating. Where would be the best place to publish these readings in the documentation? Prior to measuring the power readings myself I tried to search for OVMS power consumption in the docs but could not find any results. How about adding a new section to readthedocs called "technical specs"? On Wed, 23 Oct 2019 at 18:32, <ovmsdev-request@lists.openvehicles.com> wrote:

Glyn,
Powered exclusively by ext12v, @12v, I get:
Wifi off/sleeping: 25mA Wifi only: 49mA Wifi + 3G: 85mA
Powered exclusively by USB, @5v, I get:
Wifi off/sleeping: 46mA Wifi only: 104mA Wifi + 3G: 180mA
Note that in areas of low signal, the 3G power consumption can be higher. Similarly, if GPS is enabled that can have an affect as well. I?ve never seen it go over about 220mA (and even that was just for short bursts).
If I power it from both USB and 12V simultaneously, I get:
Wifi off/sleeping: 8mA (USB 5v) and 19mA (ext 12v) Deep sleep: 8mA (USB 5v) and <1mA (ext 12v)
(The 8mA is mostly from the CP2102 which is powered off when not in use)
Regards, Mark

I've just measured the power consumption of the OVMS V3 module using a bench power supply set to exactly 12.0V.
OVMS consumed:
60mA = 0.72W with WiFi on (AP active) and GSM/GPS modem off 100mA = 1.2W with everything switched on.
This is less than I was expecting, I would take weeks for OVMS to drain a healthy lead acid battery.
