I only just started playing with RM 4 today and I'm trying to use the Connectors and Global Variables for the first time as well (I know, I delayed this for a LONG time).
In any case I'm trying to update a global variable and have it display on the dashboard but I'm obviously missing something.
Here's the connector device page states (Virtual Omni Sensor):
So the GV seeems to get updated correctly by the rule but these updates are not being reflected in the Connector device. I added the connector to a dashboard as a Variable String and if I change the value through the dashboard, it updates correctly on the device page. For some reason setting the GV value in a rule does not reflect in the device attibutes.
Looking more closely at your GV section, there is not * for the "In use by" column. So remove that connector, and do it again. There must be an * showing for it to work.
This time I deleted the GV altogether and recreated both the GV and the connector. Still no *. I'll try recreating the rule unless you have another suggestion @bravenel.
@bravenel, I also just realised I'm running 2.1.4.111 on my dev hub. It may be an old bug since there have been a few updates since then. Going to update a d they again.
Sorry for wasting your time Bruce. I updated to the latest firmware and when I created the Connector it was a RM Connector Variable instead of a Virtual Omni Sensor. All is working as designed. Not to self...always check firmware version before posting.
