From 962dc58e13349c7c9947dceec3ad62777afc06e2 Mon Sep 17 00:00:00 2001 From: Jussi Koskela Date: Mon, 29 Jun 2020 16:35:59 +0300 Subject: [PATCH] Configurable prefix and suffix text for monitors These can be used to show the attribute name and unit while keeping the value editable. To be decided if this should be merged to Platform or if the implementation should be duplicated to product.
