All seemed acceptable.<div class=""><br class=""></div><div class="">There is really not much we can do about power consumption when the system is operational. These modems use power (especially when they transmit). OVMS v2 used linear regulators, and v3 uses switching power supplies, so this is probably as good as it will get.</div><div class=""><br class=""></div><div class="">What we have done in v3 (apart from change to switching power supplies) is make sure we have full sleep and power control of each and every peripheral. This means that in software we can selectively sleep/awake and power on/off individual devices as necessary. This is done right down to the individual component chip levels. In full deep sleep, with everything unessential powered down, we can get to about 1mA. The partnership with Hologram should also allow us to put the modems into sleep mode, and use SMS messages (sent via Hologram API from the OVMS server when an App connects) to wake up.</div><div class=""><br class=""></div><div class="">Regards, Mark.<br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On 12 Mar 2018, at 6:08 PM, M B <<a href="mailto:vwir@outlook.com" class="">vwir@outlook.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class="">
