x10 with Heyu Unable to get status of devices

[lukxz76]

I've configured Heyu and all works fine without an essential command:
"heyu status Hx"
It's strange because in heyu monitor the 2-way module answer correctly but heyu does not receive the command correctly. I would like to schedule a "heyu status" in order to catch device changes operated directly using home switch that heyu does not received without that command.
I've tried using both v2.10.1 and v2.11-rc3 with the same issue

below the result of "heyu status A10" command

following "heyu monitor" result
05/20 22:28:11 sndc addr unit 10 : hu A10 (no_alias)
05/20 22:28:12 sndc func StatusReq : hc A
05/20 22:28:13 rcvi addr unit 10 : hu A10 (no_alias)
05/20 22:28:13 rcvi func StatusOff : hc A

at the same time, the "heyu status A10" command returns:
Unable to send command bytes

following output of "heyu -v status A10" commands:

Unfortunately, Yahoo groups have been decommissioned, and I have no idea if any group archives exist. Converting to QA discussion anyway.
