Hi przemom,

We released version 3.2.1 of the TCP/IP data source, which includes the changes from that issue to make it more robust. Give it a try!

I would expect so, yes.

Hi przemom,

Meta point scripts don't have the .set() function like a scripting data source does. So, your options are either to use a point link from your meta point to your modbus point, or to configure a scripting data source to set the value using varName.set( 12.34 );

My RPI is a testing machine, so I test mango and openhab. I added memory-small.sh with changes You suggested. Tomorrow I will let You know if it help. Thanks

Glad to hear it!

Hi prezemom,

It's not really possible to give a limit in terms of data points, since different configurations will entail wildly different workloads for the Mango server (it is possible to write Meta points that slow everything down a lot, if you try). Generally, though, 5000 points shouldn't pose any problem. As far as HTTP, you can see that parsing 5000 values out of 1 page request is less work than 5000 data sources requesting 5000 pages to get 1 value. I would expect both to work on a fairly modest machine (four cores, 4-8Gb ram). We have many deployments with 20000 or more points, and some significantly larger than that.

Both the H2 and MySQL backends will handle 5000 points no problem. If you get significantly larger you may find reasons to prefer MySQL. The NoSQL database is also nice to have if you're taking in dense data, or lots of it, or if you intend to keep the values at the instance very long (without the NoSQL, you will store the values in a SQL table, which can slow things down over time).

Glad to hear it!

@przemom We have released Mango 2.8.0 for testing which supports much better and easier localization, Mango will automatically detect your locale from the OS and use this for translations and date formatting (in the dashboards). All you need to do is place your translations file in overrides/properties as described above. If for some reason Mango is not using your OS locale or you want to override it, you can start Mango with java command line options such as -Duser.country=PL -Duser.language=pl

If you want to wait there will be a 2.8 release in the store soon for automatic upgrades.

Hi,
Thanks for answer. Problem solved...proxy server blocked OPTIONS reguests.
