Hello,

I am a brand new member on this fabulous forum. I have created a MySQL DB to collect datas from buildings (with Node-Red). I would like to connect Haystack to my database. How can I do ?

If you want to let people read your data via Haystack, then you would create a Haystack server that fronts your RDBMS. Depending on what kind of data you are storing in the RDBMS, you might implement a few ops like "read" and "hisRead" to let clients access your data. Or even more simple maybe just create a script to dump your database to one of the Haystack formats such as JSON.

OK, thank you. I have cretad a json file with Node-Red. I need this file to be readen by Haystack now.

Check out this project for some reference material on Haystack:

Thank you. I have setup this project in my server. I can read sites and points with this kind of url : http://192.168.69.10:8080/haystack/read?filter=point.

But, I don't know how to integrate haystack tags and values of my points.

I use mosquitto broker and Node-Red. My datas are sent to MySQL.

In these settings, I don't how to implemente Haystack.
