I am using a Reactor plugin to read temperature values via http-get command from Tasmota devices and write them to VirtualSensors in Vera. All works great thanks to the genius plugins from Patrick H. Rigney.
Just have one exception that I would like to catch. If anything wrong happens and Tasmota does not supply the current temperature - the Expression holding the value in Reactor is set to (null) - as desired.
But when the Device Action SetValue is executed by Reactor against a VirtualSensor with that (null) value - nothing happens.
The VirtualSensor still retains the previous value, instead of getting a value of (null).
This is misleading, because in my dashboard I see the old value, and I would like to see that the Tasmota sensor failed and that I should fix it.
Is it possible to change that behaviour?
Can I set the value of my VirtualSensor to (null) with the Reactor plugin?
