I'm using an ESP8266 NodeMCU-12e, connecting to Cayenne IOT platform. Most things work fine (I can update most widgets using virtual channels), but some widgets are unavailable (greyed-out), or simply don't work.
For example, trying to add a Generic Sensor (or generic actuator etc):
...or Luminosity Sensor:
...the "Select Device" drop down is greyed out, and I can't proceed any further with configuring and adding the widget.
If I manually add a 2-State widget, I can configure and add it, but even though the on/off trigger data is being received by Cayenne, the widget does not toggle on/off. It remains in an always-off state no matter what.
I've tried adding my device as a Generic ESP device, as well as a "Bring your own device", to no avail.
I've scoured for hours online, but haven't found anything. Does anyone know what the problem may be?
