Ab und an verliert Homegear-Gateway die Verbindung zur Basis. Leider stelle ich das erst fest, wenn mal die weit entfernten Geräte nur verzögert oder gar nicht reagieren.
Es wäre schön, wenn man in node-blue auf das nicht erreichbare Gateway reagieren könnte. Im Admin-UI wird das Gateway als disconnected angezeigt, die Information ist also da.
Interessant waere auch rauszufinden wieso die Verbindung verloren geht … also jetzt nicht als Status, sondern so generell …

Ja, du hast recht. 
Ich schau es mir mal an:

Kann es sein, dass die Verbindung immer wieder zusammenbricht, aus irgendeinem Grund und irgendwann die verfügbaren Verbindungen auslaufen?
Diese Meldungen kommen teilweise sekündlich (über Stunden), und verschwinden dann sang- und klanglos wieder.

Ich weiss, cool wäre es, wenn die Daten besser zusammenpassen würden, tun sie aber nicht. Es gibt aber schon ein paar Zeilennummern und Anhaltspunkte:
Da müsste man mal reinschauen, ob das miteinander zusammenhängt.
OK,

Oha, das schlimmste, was passieren kann. Eine Exception beim Exception-Handling. Da muss @sathya ran.

Und noch einmal.
Entweder habe ich etwas falsch verstanden, oder hier tritt das Gleiche auf. Kann natürlich auch sein, dass die angegebene Zeilennummer nicht die Zeile der Exception, sondern nur die Zeile des Outputs ist.
Hallo @job,
Genau, das ist die Zeile, in welcher die Fehlermeldung generiert wird, nicht die Ausnahme selbst. Anletztere Info kommt man in C++ (meines Wissens) leider nicht ran.
Der RPC-Server erlaubt am Gateway nur eine Verbindung zur Zeit. Diese scheint aber inaktiv zu sein. Trotzdem wird sie nicht geschlossen und das Gateway erlaubt keine neue Verbindung. Die Fragen sind also:
Ich habe schon einmal kurz geschaut, auf den ersten Blick sieht alles gut aus. Ich muss mir das aber noch einmal genauer ansehen.
Zu deiner initialen Frage:
Du kannst in einer function-Node $hg->listInterfaces(); (https://ref.homegear.eu/rpc.html#listInterfaces) aufrufen. Da siehst du, ob dieses verbunden ist, oder nicht (Schlüssel CONNECTED).
Viele Grüße
