Witch Plugin I can use to do an event table, example:
High pressure, 2021-05-11 12:00:00
low pressure, 2021-05-11 12:10:00
I am connecting bool(false or true) value into a DB, I will also need an example
There are lots of databases that you can use. Do you have any databases (Prometheus, Loki, InfluxDB, MySQL, Postgres) installed already?
Grafana is a visualization tool that you can use together with a lot of different databases.
Maybe InfluxDB together with Grafana would be suitable if you are measuring pressure.
I think most databases can do that. If you have any experience with a database then I would use that. If this is your first time using any database then something like InfluxDB or Loki is probably the place to start.
The Loki data source is already included in Grafana. You will need to either set up Loki yourself (it is open source): Grafana Loki | Grafana Labs Or you can use Grafana Lab’s Hosted Loki that comes with a free tier: Get started with Loki on Grafana Cloud | Grafana Labs
InfluxDB is a time series data but is also commonly used for logs/events. Link in previous post. InfluxDB also has a hosted version.
