Does the iotawatt base unit include a wall mount allowing mounting the unit to European DIN rails?
I do not believe so, the image below shows the mounting bracket I received with my unit. It is more designed to mount to a flat surface. The piece with 4 screw holes mounts to a solid object such as a paneled (wood) wall. The second (smaller) piece with two screw holes attaches to the back of the IoTaWatt unit and they clip together.
