Thanks..
1) Firmware 5.3.0 but same behavior on 5.3.4
2) UI and firmware match on both cases, and now double-checked on 5.3.4
3) It's a node server to control lamp switches. So ON/OFF is just to turn them on/off...
4) Trying to do it on the java console, ISY is connected to Node Server, the status of each item on node server get updated to ISY (physically turning them on, gets updated to isy, but I cannot send any command from isy to them, so no programing or scenes are possible
5) Yes MAC OS, but I'm a long term user of it, never created any problem for me with ISY over more than ~10 years
6) Yes, from Brazil
Already looked into the errors but found no clue in how to fix it.
Tried with @xKing because it's involving a node server wrote from him, but after sharing some info, the issue was narrowed down to a point where ISY receives updates from the node, but cannot "start or send" communication/commands.
I've really digged into several pages here, could not find some clear answer to it... I don't recall having to open a ticket so far, but I'll do it. THANKs !!!!
