The ELM327 devices are great to tinker around with but they’re a bit hard to build a “polished” application around. And monitoring without a mobile device and the car on just won’t work with them.
For production Carvoyant accounts, we have several devices that we support (we don’t build our own hardware, we’re a middleware/api platform that uses off the shelf hardware that we purchase wholesale). Pricing for consumers currently is $99 / year. That includes hardware, connectivity and unlimited (both loosely throttled) API access to your account. If you’re interested in buying hardware, you can order it here. Developers looking to build and distribute applications on our platform have different pricing arrangements. Drop me an email offline (firstname.lastname@example.org) if you want more information about that. I don’t want to this into a marketing thread :).
@zj4x4 - Couple of things. The feature we are showing here are ignition start and stop and geofence based on GPS location. Lock and unlock of vehicle doors are not supported by the current generation of consumer OBDII devices. GPS will work on all OBDII equipped vehicles. Other features are dependent on the year/make/model. Pure electric vehicles have very poor support in these devices. Hybrid vehicles or vehicles with engine off economy modes (ie, engine off at a stop) will collect data but the “ignition” cycle is detected when the gas engine turns on or off. If you let me know what kind of vehicle(s) you’re looking at connecting I can let you know our experiences with them, if any.
For all purchases, we do offer a full refund within 60 days if the device does not work as expected in your vehicle. As I said, consumer pricing is a flat $99/year/device, API calls are included in there. The $1/month pricing is if you are selling an application that other Carvoyant users are using, which is probably not applicable to anyone on here.
Having said all that, I really really would like you all to play around against our sandbox before you consider a hardware purchase. We’re new to SmartThings and it’s quite likely the code we posted will need some tweaking. I don’t want anyone ordering under the assumption that it’s going to work a certain way in ST and then it doesn’t. Of course, you’ve got 60 days to return it if you decide. Your call!
