4 years ago You can fix this by:
-
Install the MapDB Persistence addon. This is an embedded database that is very light weight and very fast. It only saves one value for each configured Item.
-
Create a
Group RestoreOnStartupand add all the Items that need to be restored to what ever state they had prior to OH restarting. So far I've applied the Group to- all the TempSetpoint Items
- PreviousTempReading
- HumiSetpoint
- PreviousHumiReading
- All the BoostTime Items
- All the Mode Items
- Heating2
- MainSwitch
- System_TZ and System_TZ_Set // We've got to find a better way to set the TZ
- BackuptimestampCommand
- Heating2Time and Heating2Delta
- TempUnit
- SystemType
- HumidityType
-
Create conf/persistence/mapdb.persist
Strategies {
everyMinute : "0 */1 * * * ?"
default = everyChange
}
Items {
RestoreOnStartup* : strategy = everyChange, restoreOnStartup
}The RestoreOnStartup* means save the state for all members of the Group RestoreOnStartup according to the defined strategies. everyChange will cause the state of the Item to be saved every time it changes. restoreOnStartup means OH will read the value stored in the database and update the configured Items to that state. Usually this occurs before Rules will start executing but sometimes not (I've a fix for this too, stay tuned) so it's important to check for NULL states in Rules that use these Items to avoid errors.
The states won't be saved to the database until the Item changes state so you might want to use the everyMinute strategy for awhile so all the Items states get saved. Or you can use the UI or REST API to change all the Items manually or write a temporary Rule to initialize the values.
- Update the System started Rule to remove all of the commands and updates that revert everything to a default value. The following is what I'm testing with right now:
rule "Initialisation"
when
System started
then
logInfo("initialization", "Initialization starting!")
// MainSwitch.sendCommand("OFF");
// HeatingMode.sendCommand("OFF");
// CoolingMode.sendCommand("OFF");
// FanMode.sendCommand("OFF");
Heating2.sendCommand("OFF");
if (TempUnit.state == "C") {
if((TempSetpoint.state == NULL) || (TempSetpoint.state == UNDEF)) postUpdate(TempSetpoint, 18);
if((TempSetpointC.state == NULL) || (TempSetpointC.state == UNDEF)) postUpdate(TempSetpointC, 18);
if(TempSetpoint.state > 40) postUpdate(TempSetpoint, 18);
if(TempSetpointC.state > 40) postUpdate(TempSetpointC, 18);
} else {
if((TempSetpoint.state == NULL) || (TempSetpoint.state == UNDEF)) postUpdate(TempSetpoint, 70);
if((TempSetpointF.state == NULL) || (TempSetpointF.state == UNDEF)) postUpdate(TempSetpointF, 70);
if(TempSetpoint.state < 32) postUpdate(TempSetpoint, 70);
if(TempSetpointF.state < 32) postUpdate(TempSetpointF, 70);
}
if((HeatingBoostTime.state == NULL) || (HeatingBoostTime.state == UNDEF)) HeatingBoostTime.sendCommand(10);
if((CoolingBoostTime.state == NULL) || (CoolingBoostTime.state == UNDEF)) CoolingBoostTime.sendCommand(10);
// postUpdate(PreviousTempReading, 0);
// postUpdate(PreviousHumiReading, 0);
// Heating2Time.sendCommand(0);
// Heating2Delta.sendCommand(0);
Network_WLAN_IP.sendCommand(executeCommandLine("/home/pi/scripts/getwlan0ip.sh",60000));
Network_SSID.sendCommand(executeCommandLine("/home/pi/scripts/getssid.sh",60000));
Network_WLAN_INFO.sendCommand(executeCommandLine("/home/pi/scripts/getwifiinfo.sh",60000));
Network_WLAN_MAC.sendCommand(executeCommandLine("/home/pi/scripts/getwlan0mac.sh",60000));
System_CPU_TEMP.sendCommand(executeCommandLine("/home/pi/scripts/getcputemperature.sh",60000));
System_CPU_LOAD.sendCommand(executeCommandLine("/home/pi/scripts/getcpuload.sh",60000));
System_Used_Space.sendCommand(executeCommandLine("/home/pi/scripts/getuseddiskspace.sh",60000));
// TempUnit.sendCommand(executeCommandLine("/home/pi/scripts/gettempunit.sh",60000));
// SystemType.sendCommand(executeCommandLine("/home/pi/scripts/getsystemtype.sh",60000));
endI'm not ready to submit it as a PR just yet because I think you will want to check all these Items and if they are NULL or UNDEF than apply a default value to them similar to the way the TempSetpoint Items are checked and the values sanitized. I'm also not certain of any side effects I may have introduced. Also, this is based on the released code, not the latest version checked in to this repo.
But this should be enough to get you started.
The actual database get's stored in /var/lib/openhab2/persistence/mapdb which is included when you run the backup script. So if you restore from a backup you will also restore these Item's states.

If set ON, it is lost on a reboot/update/restore
