    <description>&lt;P&gt;Hallo,&lt;/P&gt;&lt;P&gt;ich benutze einen Vitodens 100 mit Vitoconnect OT2. Seit etwa einer Woche kann sich Vitoconnect nicht mit dem Wi-Fi verbinden, was durch ein rotes Wi-Fi-Symbol auf dem Gerät angezeigt wird.&lt;/P&gt;&lt;P&gt;Ich habe die folgenden Schritte zur Fehlerbehebung ausprobiert:&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;UL&gt;&lt;LI&gt;Die Android-App neu installieren&lt;/LI&gt;&lt;LI&gt;Die Daten und den Cache der App löschen&lt;/LI&gt;&lt;LI&gt;Vitoconnect zurücksetzen (den Knopf auf OT2 für 30 Sekunden halten)&lt;/LI&gt;&lt;LI&gt;Vitoconnect OT2 ein- und ausschalten&lt;/LI&gt;&lt;LI&gt;Vitoconnect OT2 mit verschiedenen Wi-Fi-Routern und Netzwerken verbinden&lt;/LI&gt;&lt;LI&gt;Vitoconnect OT2 mehrfach zu meinem Viessmann-Konto hinzufügen&lt;/LI&gt;&lt;/UL&gt;&lt;P&gt;Ich habe auch Vitoconnect-Logs gesammelt, Die Log-Datei enthält mehrere Fehler.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Jan 1 01:02:04 vitoconnect local1.info lightls::model[386]: Setting data (id='25', value='3fcd02', quality=0)&lt;BR /&gt;Jan 1 01:02:06 vitoconnect local1.info hb2networkcontrol[386]: Changed Network-Property = network.wlan.sta.credential_status&lt;BR /&gt;Jan 1 01:02:06 vitoconnect local1.info hb2networkcontrol[386]: Changed Network-Property-Value = correct&lt;BR /&gt;Jan 1 01:02:06 vitoconnect local1.info hb2app[386]: Storing system properties.&lt;BR /&gt;Jan 1 01:02:06 vitoconnect local1.crit hb2commonpropertieshb2common[386]: updating md5(/etc/hb2app.conf): 3489082ba206ec193ade0d4bd75c5784&lt;BR /&gt;Jan 1 01:02:06 vitoconnect local1.info hb2localhandling[386]: device_error_state_ = kErrorState_Active&lt;BR /&gt;Jan 1 01:02:06 vitoconnect local1.info hb2dceadapter_[386]: USING DEFAULT URL!&lt;BR /&gt;Jan 1 01:02:06 vitoconnect local1.info hb2dceadapter_[386]: Successfully requested connection to backend (code 0)&lt;BR /&gt;Jul 13 20:45:41 vitoconnect local1.info lightls::dhw[386]: Setting temperature setpoint (t=50.000000)&lt;BR /&gt;Jul 13 20:45:41 vitoconnect local1.info lightls::dhw[386]: Result=0&lt;BR /&gt;Jul 13 20:45:41 vitoconnect local1.err hb2dceadapter_[386]: ID TimeProgramActiveSetpointCh1 not sent: invalid size (7 bytes of max. 0)!&lt;BR /&gt;Jul 13 20:45:41 vitoconnect local1.err hb2dceadapter_[386]: ID HeatingCircuitStateCh1 not sent: invalid size (11 bytes of max. 0)!&lt;BR /&gt;Jul 13 20:45:42 vitoconnect local1.info llsadapter[386]: On data value (id='56', size=3)&lt;BR /&gt;Jul 13 20:45:42 vitoconnect local1.err hb2dceadapter_[386]: error: DCe connection reported error 8.&lt;BR /&gt;Jul 13 20:45:42 vitoconnect local1.info hb2dceadapter_[386]: Backend connection reported an error!&lt;BR /&gt;Jul 13 20:45:42 vitoconnect local1.info hb2localhandling[386]: device_error_state_ = kErrorState_Active&lt;BR /&gt;Jul 13 20:45:44 vitoconnect local1.err hb2dceadapter_[386]: error: DCe connection reported error 8.&lt;BR /&gt;Jul 13 20:45:44 vitoconnect local1.info hb2dceadapter_[386]: Backend connection reported an error!&lt;BR /&gt;Jul 13 20:45:46 vitoconnect local1.err hb2dceadapter_[386]: error: DCe connection reported error 8.&lt;BR /&gt;Jul 13 20:45:46 vitoconnect local1.info hb2dceadapter_[386]: Backend connection reported an error!&lt;BR /&gt;Jul 13 20:45:50 vitoconnect local1.err hb2dceadapter_[386]: error: DCe connection reported error 8.&lt;BR /&gt;Jul 13 20:45:50 vitoconnect local1.info hb2dceadapter_[386]: Backend connection reported an error!&lt;BR /&gt;Jul 13 20:45:51 vitoconnect local1.err hb2dceadapter_[386]: ID wifi_strength not sent: invalid size (1 bytes of max. 0)!&lt;BR /&gt;Jul 13 20:45:51 vitoconnect local1.err hb2dceadapter_[386]: ID wifi_channel not sent: invalid size (1 bytes of max. 0)!&lt;BR /&gt;Jul 13 20:45:54 vitoconnect local1.info hb2localhandling[386]: Toggle accesspoint mode (UI)&lt;BR /&gt;Jul 13 20:45:57 vitoconnect local1.err hb2dceadapter_[386]: error: DCe connection reported error 8.&lt;BR /&gt;Jul 13 20:45:57 vitoconnect local1.info hb2dceadapter_[386]: Backend connection reported an error!&lt;BR /&gt;Jul 13 20:46:01 vitoconnect local1.err hb2dceadapter_[386]: ID wifi_strength not sent: invalid size (1 bytes of max. 0)!&lt;BR /&gt;Jul 13 20:46:01 vitoconnect local1.err hb2dceadapter_[386]: ID wifi_channel not sent: invalid size (1 bytes of max. 0)!&lt;BR /&gt;Jul 13 18:46:02 vitoconnect user.info kernel: [ 146.865275] wlan.sta: deauthenticating from 36:e3:48:cc:df:f3 by local choice (Reason: 3=DEAUTH_LEAVING)&lt;BR /&gt;Jul 13 18:46:02 vitoconnect user.debug kernel: [ 146.902744] cfg80211: All devices are disconnected, going to restore regulatory settings&lt;BR /&gt;Jul 13 18:46:02 vitoconnect user.debug kernel: [ 146.902773] cfg80211: Restoring regulatory settings while preserving user preference for: DE&lt;BR /&gt;Jul 13 18:46:02 vitoconnect user.debug kernel: [ 146.902790] cfg80211: Kicking the queue&lt;BR /&gt;Jul 13 20:46:02 vitoconnect user.notice root: /usr/bin/cm/ap/././../common/destroy_wlan_interfaces.sh: WLAN wlan.sta interface destroyed.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>
