@roberto Really supportive of the community to join this discussion.
I see there is a desire by the community unmet by what you're able to provide: local LAN controller. The obvious reasons include both the complexity that you might have in various cloud services that would be difficult to setup in a small LAN, the variance in server hardware or software to host the controller, and the IP that might become obvious if you ship a parsed language such as python.
This might actually be mitigated if you're willing to offer a docker image of a controller: supporting (or not-supporting: support yourselves, hackers!) is more consistent if one docker image can run on whatever orchestration we use, and we gain the ability to hit a local resource without uptime and latency and cloud-ness to worry about.
Understanding the subtle-but-continuous increase of cost in cloud services, this allows your uber-elite users that may generate above-average query load to shunt this load to their own resources.
Additionally, you'd seem like even more awesome people for doing this. Very cutting-edge. Define the next level of customer interaction and independence, GDPR privacy issues, etc.
I bet if you made a dummy service -- some go routine or python flask that simply responds with logical bogus values -- the open source community would build the docker image for you. Overnight.
Anyhow, it's a thought.
