My Devices VS Hologram.io

I've used outdoor soil sensors from mydevices.com. Once I told them to stop trying to upsell me on the Lora gateways and use Helium, its worked flawlessly. Its been like 6 months and the battery still registers 100%. Reports every 15 minutes and the data credits find their way to 3-4 different hotspots in the area. Source: over 2 years ago

OVMS is a not cheap module. It comes with a hologram.io SIM card, but you can use any data-only LTE plan. Cost for the module is over $250, and then you'll have to pay somewhere south of $5/mo for a data plan if you go with hologram.io. Source: about 1 year ago

An LTE plan from hologram.io is a few bucks a month... And I'd gladly pay it and not give my money to OnStar's broken stuff :-). Source: over 1 year ago
