+  * sunspec: package the vendored SunSpec plugin as nymea-plugin-sunspec-etm01.
+    The plugin was added to the build by the vendoring commit but never
+    packaged, so dh_missing found its .so in debian/tmp with nowhere to install
+    it and aborted the whole source package: no binary package at all came out
+    of this branch, not even for the four unrelated plugins.
+  * sunspec: add the Fronius vendor. A GEN24 answers for the inverter on one
+    unit ID and for its Smart Meter on another, behind the same host and port,
+    so one froniusConnection thing now carries two SunSpecConnection objects.
+    The meter connection is brought up only once the primary has finished
+    discovering, and the parent connected state follows the primary alone.
+  * sunspec: correct the storage setpoint chain - charge and discharge rates
+    read back from InWRte/OutWRte instead of the read-only gradients, the rate
+    range widened to -100..100 so forced charging can be expressed at all,
+    enableDischarging reconciled from StorCtl_Mod, and the revert timer armed
+    with every setpoint so one left behind by a stopped HEMS expires.
+  * debian: add libnymea-sunspec-dev to Build-Depends. Upstream does not need
+    it because it builds libnymea-sunspec from the same source tree; this
+    repository vendors only the plugin and links against the installed library.
+  * The new binary package conflicts with, replaces and provides
+    nymea-plugin-sunspec: it ships the same plugin file and the same pluginId
+    as the upstream package this repository already mirrors.
