So you’ve disabled the Cloud connection then, relying on a local connection only, I presume? I mean, after all, Particle is a third party as well… Plot.ly is a third party as well…?
You could host a DIY server solution that’ll store/plot this data for you. If you do a quick google, I’m sure you’ll find plenty.
If that’s not what you’re after, then maybe, just maybe you’d need to put in a bit effort of your own, and set aside your prejudice against third parties. Ranting about the current situation isn’t going to be much of a solution either, unless that somehow magically solves your issues.
What is your final goal with these devices, might I ask? They’re labeled as ‘development kits’, the ‘development’ part is there for a reason.
Again, instead of complaining about the lack of something to control the relays, why not making an effort to create it? (never mind that there are several easy to use solutions out there already) The platform is open-source, and as such it’s intended for people to at least make an effort. If that’s not something you’re willing to do, then perhaps you’re better of buying a finished product, or hiring someone to build one for you.
You can’t compare a linux board to an embedded device, they each have their purpose. Just my two cents.
