Greg, Mark disabled the 12V alerts on the roadster firmware some commits ago. Regarding the alert configuration: commit 9c1a991a9a27de8afdc9fd408262a2fe0be7aef4 Author: Michael Balzer <balzer@expeedo.de> Date: Mon Apr 30 22:39:05 2018 +0200 Vehicle: 12V battery monitoring & alert New configs: - vehicle [12v.alert] = 1.6 Voltage drop alert threshold in V vs. reference New metrics: - v.b.12v.voltage.ref 12V reference voltage [V] - v.b.12v.voltage.alert Alert status (bool) This works like the old V2 12V monitoring, just a bit improved. The reference voltage is taken after max 15 minutes calmdown time after 12V charging stops. The initial reference is the first voltage measured at boot. Also, the AD conversion needs to be calibrated for each module, to compensate component tolerances. If you haven't done that for your modules yet, their 12V measurements will differ. To calibrate, measure your real 12V level and change config system.adc factor12v accordingly for each module. Regards, Michael Am 19.05.2018 um 02:26 schrieb Greg D.:
Hi folks,
I'm getting alerts from OVMS that my 12v battery is failing, as it's dropped below the threshold, which is set to 13v for some reason. So I get a notification every time the car transitions from awake to asleep.
I don't see a configuration item, nor anything in the OVMS v2 app. Oddly, the threshold is 13.2 for my v3.0 proto module, but I can't find a config item there either.
How do I change the threshold?
Greg
