M-Bus

[stonecroft]

Hello.

I'm trying to read M-Bus meters with external Serial to M-Bus gateway (Tecbase Mbus 10 RS232-Mbus) according to http://openrb.com/m-bus-integration-in-lm

When I try to read meter data I get *nil in return.
Scan the bus and change short address is working so connection to M-Bus meter seems to work.
Any ideas what I'm doing wrong?

What error do you get in Alerts tab?

No error in Alerts tab, just *nil in Logs tab.
If I try to read wrong short address or change short address I get meassge in Alerts tab.

Example script is wrong, it should have log(res) instead of log(data)

Perfect, now it works 

Thanks
