Hi all, Thanks to Michaels last message to remind me to ask a question here: Since a few months, maybe a bit more because it happens only once in a while, I have noticed I wasn't receiving the SMS alerts (feature on SMSIP mode) , and sending a "Stats?" only gave me the nasty access denied answer. It turns out, using the application, I noticed that the phone number was getting corrupted (afaik, it's the only setting affected) Normally: "+33651886877" it became "+336k1886877" or "+33651886Z77" etc... like a solar flare bit flip ! It seems it happens only upon reconnection of the ovms module the the OBD plug (Twizy) as, well, the 12V battery, though brand new, can't last a weekend (car parked underground, I suppose the GSM needs to force a bit too much) So question: Has any one suffered from such an issue ? And, otherwise, Michael might be able to tell: Would having the feature on SMS only (without IP) consume less energy ? If so, would it possible to imagine a Hybrid mode, IP active only if vehicle on charge or keyon ? Thanks, JaXX, PS: Despite winter, thinking of building a solar panel + thin plexi sandwich for the rooftop, just because of the 12V battery :-) Only recent twizys can charge the 12V from the traction battery when resting.
