Hi. I know this is an old post and you are probably ok now however one thing I have found from experience is that mysensors data doesn't always appear in sitemaps unless the data is formatted correctly. However you should still be seeing the channel being updated in the openhab log. These are examples of formatting that have worked for me:
Frame label="Sensor 1"
{
Text item=MySensorsDevice10_Humidity label="Hum [%.1f %%]"
Text item=MySensorsDevice10_LastUpdate label="Last seen [%1$tA, %1$td/%1$tm/%1$tY %1$tH:%1$tM]" icon="network"
Text item=MySensorsDevice11_Temperature label="Temp [%.2f °C]"
Text item=MySensorsDevice10_BatteryLevel label="Batt [%.1f %%]"
}
I have now found I can replicate this behaviour by simply restarting the serial monitor in arduino ide (i.e. forcing the bridge to restart). Once done the bridge thing and node things all show as online but no updates are made until the things are edited in some way.
In the relay actuator example the methods saveState() and loadState() are used. The current status of the pin (RELAY_ON or RELAY_OFF) is stored in the EEPROM with every change and restored after a restart of the node.
The node will return to the last known state after a restart.
BUT: while restarting the state of the pin may change (from on to off to on again while booting up). In case you want the relays to stay activated while booting up you may use an external pull up.
