The NodeRED node Emoncms does not post numeric value zero

Hi,
The input value in emoncms.org is not changing if NodeRED node Emoncms posts numerical value zero. It works fine with other values except zero. Also if value is boolean FALSE than value zero is received.

Already discussed with NodeRED community and testing shows the node Emoncms is probably working correct:

It looks like emoncms does not processed the JSON post if value is zero.
Any suggestions or similar experience?

Regards, Igor
