I heard from a gas guy that this is to ensure that only connectors made for gas usage are used and people don’t build crazy contraptions with plumber gear for flammable gases… Kinda makes sense.

I do not know Airtable too well, but n8n might have a connector for it. Then you could use the rest. good luck!

I am using appsmith for the app, with a pgsql db. Then n8n to query pgsql with its JSON functions and finally sending it to apitemplate.io to generate a PDF from the JSON and a template. The PDF then goes into nextcloud. With apitemplate you get 50 executions a month for free, which is enough for my use case. Hope this helps. (The use case is an equipment maintenance tool for the SCBAs of our fire brigade, where I need reporting for proving that maintenance was carried out)

You are welcome!

In Chemistry (where it originated) it is still called NMR. There is no image produced, but a spectrum (graph).
