Points to Consider
- HVAC equipment (and IoT in general) often differs from server architecture (Grafana origins) in regards to data bandwidths, with some devices connected on SIM cards or radios with very little data use available.
- Needs to remain compatible with the standard 5 level MQTT structure (Network_Id / Node_Id / Device_Id / Group / Key) so that dashboards based on named devices can be shared easily. The Network_Id will be the only variable that changes.
- With limited data bandwidth, installations can make use of a data concentrator, a controller that generates summary statistics and alarms from groups of devices on a local network, that can then be sent over the limited uplink bandwidth.
- It is required to make use of a data request function (a sync), whereby all (or specific) data on a device can be requested for publishing. This allows for high resolution historic data held on a controller that would not normally be published, to be remotely requested, published, and then accessed in the even of problems. Such a function would also apply to detailed system data and files.
- Two communication is required, with a need to implement user commands. Examples include remote control over central heating, or the facility to switch equipment between on / off / auto states.
Setting up for reverse proxy
Open a console into container.
Shell into Grafana and edit ini. May need to install nano
apk update apk add nano
nano /usr/share/grafana/conf/defaults.ini
Scroll down and alter to...
# The public facing domain name used to access grafana from a browser domain = hwwiki.ddns.net # Redirect to correct domain if host header does not match domain # Prevents DNS rebinding attacks enforce_domain = false # The full public facing url #root_url = %(protocol)s://%(domain)s:%(http_port)s/ root_url = %(protocol)s://%(domain)s:/dashboard/ # Serve Grafana from subpath specified in `root_url` setting. By default it is set to `false` for compatibility reasons. serve_from_sub_path = true
At the bottom you can also set an anonymous login to allow access without a password.
Restart container
