Bit of a non-technical one, sorry if this is the wrong sub-forum.
I run facilities for three hotels. We have about 40 sensors on Hermetry right now, mostly boiler room temps, a few water meters and the walk-in freezers. Works fine, the boards are great for my team.
Now our new IT lead keeps saying we should be on something “fully open source that we host ourselves” so we are not locked in. I don’t really know how to answer him. His questions, more or less word for word:
- where physically is our data
- can we get all of it out if we leave
- can it run on our own servers
I’d rather not move everything, it took me months to get here. Any of you had this conversation with IT?
Had nearly the same chat with a client’s IT last year. Pretty sure you can run it on your own box, there’s a docker image somewhere? Don’t quote me though, we’re on the cloud one.
A docker image would make him very happy. Where would I find that? I looked under Settings and only see Residency, Data Export and the usual stuff.
Careful, I don’t think there’s a download-and-run image. The plans page says on-premises installs are agreed with their sales team, same as Enterprise plans, so that’s a conversation, not a button.
For the other two questions you can answer him today, I did exactly this for our compliance people:
Where the data is: every organisation has one home region, EU, US or Turkiye, picked when it was created. Devices, telemetry, alarms, boards, flows, audit log all live there. As owner or admin open Settings, then Residency (it’s at /admin/settings/residency). It shows the home region, any residency requirement, the region facts, the sub-processors and where backups are kept. I screenshotted that page and that was most of the answer.
Getting it out is two parts. An owner can pull a JSON export of the organisation (devices, boards, members, settings, webhooks, part of the audit log). Telemetry history goes separately, with the history API or the download on a chart card, and board files you download one board at a time. I wrote a little script that pulls hourly averages per device into CSV every month, so we always have our own copy.
Page I sent our IT: Regions and data residency, plus the “Export your data and close your organisation” one.
Tyler this is perfect. Showed him the Residency page (we’re US, no residency requirement set) and he calmed down a lot once he saw the export plus history API route. He wants your monthly CSV idea as a standing job, so I guess that’s my next project. Not mentioning the docker thing again, lol.
Yeah my bad on the docker bit, I was mixing it up with a local Node-RED box we run. Good to know about the sales route for on-prem though.
