Persistence not working for GPS location formatted XX.XXX75788937955,-X.XXXX170208076405

The issue might be a difference in the two existing influxDB persistence services

Thanks very much @MartinKo !, but didn’t work either after trying it out now. One question in this line of code:

StringLocation.postUpdate(LocationItem.state.toString())

Is LocationItem a method or a typo and should it be StringLocation?

Is there something I could do to get it to work or should I wait for an update/fix?

Sorry for being unclear in the example… LocationItem is just a name of a Location item. Your LocationItem was IPhone7Plus_L ?

Then for you it will be

StringLocation.postUpdate(IPhone7Plus_L.state.toString())

StringLocation is just an item of type String with the name StringLocation

Oh! I see now. Thanks again @MartinKo for clarifying. The item name is IPhone7Plus_Location

I tried it now, but no luck :pensive: I paste below the code converted to my system.

ITEM

String IPhone7Plus_LocString "iPhone Location String"

RULES

rule "iPhone"
when
   Item IPhone7Plus_LocString changed
then
   IPhone7Plus_LocString.postUpdate(IPhone7Plus_Location.state.toString())
end

PERSIST


Strategies {
    everyMinute : "0 * * * * ?"
    everyHour   : "0 0 * * * ?"
    everyDay    : "0 0 0 * * ?"
}

Items {
    ZWaveNode4FGMS001MotionSensor_SensorTemperature                     : strategy = everyChange, everyHour
    ZWaveNode2FGKF601Keyfob_SceneNumber                     : strategy = everyChange
    ZWaveNode3FGWP102MeteredWallPlugSwitch_ElectricMeterWatts           : strategy = everyChange
    IPhone7Plus_LocString                     : strategy = everyChange, everyHour
    ZWaveNode3FGWP102MeteredWallPlugSwitch_Switch       : strategy = everyChange
}

Your RULES file never fires right… I think it should be

rule "iPhone"
when
   Item IPhone7Plus_L changed
then
   IPhone7Plus_LocString.postUpdate(IPhone7Plus_L.state.toString())
end

This way the item IPhone7Plus_LocString gets updated when the item IPhone7Plus_L gets updated

Thanks @MartinKo and that made the trick! At least now I can get this to persist. I learned a lot with this too.

I believe that you’re right, and given this I think that something should be fixed, but at least the workaround posted by @MartinKo seems to push to influxDB the location.

As I understand it, LocationItem is new in OH2/ESH. The persistence service, being an OH1 service, only supports OH1 items/types.

Hi, I got the following error on Mqsql, how can I solve it.

2020-11-21 14:36:04.052 [ERROR] [sql.internal.MysqlPersistenceService] - mySQL: Could not create table for item ‘iPhone5_LocString’ with statement ‘CREATE TABLE Item4875 (Time DATETIME, Value VARCHAR(20000), PRIMARY KEY(Time));’: Column length too big for column ‘Value’ (max = 16383); use BLOB or TEXT instead

2020-11-21 14:36:04.054 [ERROR] [sql.internal.MysqlPersistenceService] - mySQL: Item ‘iPhone5_LocString’ was not added to the table - removing index

2020-11-21 14:36:04.113 [ERROR] [sql.internal.MysqlPersistenceService] - mySQL: Could not store item ‘iPhone5_LocString’ in database with statement ‘INSERT INTO Item4875 (TIME, VALUE) VALUES(NOW(),?) ON DUPLICATE KEY UPDATE VALUE=?;’: Table ‘OpenHAB.Item4875’ doesn’t exist

I’m sorry I don’t have a solution as it seems to be the way OpenHAB tries to create the table. It’s trying to make a column with the length on 20000 characters but MySQL is limited to 16383.
I don’t think there’s much you can do. Unless of course you create the table yourself.
You’d need to run ‘ CREATE TABLE Item4875 (Time DATETIME, Value VARCHAR(16383), PRIMARY KEY(Time));’ into MySQL.

I tried but it didn’t work
