Minimum SQL Security Requirements for Catalina API

Minimum:
db_datawriter
db_datareader
db_ddladmin

If you are going to use our userMaintenance web service, to manage SL user logins, it will also need:
db_securityadmin
db_accessadmin

Also note that by default, we normally install our scripts under the dbo schema. So, you also have to give the user, we are connecting as, execute on that schema.

eg. grant  execute on schema :: [dbo] to usernamehere

PH and Temperature Hydroponic Monitor using MQTT

There have been quite a few requests for the code for my MQTT posting IOT project for testing PH and Temperature of my hydroponic towers. This code is several years old and I haven’t looked at it for at least 2. But, I figured I would put it out on GitHub.

The main purpose of this code is to monitor the PH and temperature in a water tank for my hydroponics and then use MQTT to post to io.adafruit for a dashboard.
