As far as I know are the "PHR" series connectors a variant of the "PH" connectors. They also have a 2.0 mm pitch, but they differ slightly in their housing design. The primary difference in the "PHR" connectors is the presence of a latching feature on the housing. This latch helps to secure the connector halves together, providing additional stability and preventing accidental disconnections.

Thank you. You wouldn't recommend it's frontend for larger datasets either?
I'm already using Grafana but hoped for a seeming less integration in HA
