KNX dtp20

[claudecoppens]

Hello, to make a connection with a knx system i need to set datatype 20 (20.108) but in the list of loxone datatypes i can’t find this datatype. Someone any idea how to solve this problem ?

In the IObroker project with the adapter openknx can you use the datatype 20. https://github.com/iobroker-communit...Broker.openknx
With virtual http adapters from Loxone to IObroker you can user the values and states. I use the simpleAPI adapter for this. https://github.com/ioBroker/ioBroker.simple-api

Hello, thank you for this answer. However it concerns an installation at a customer's house where I cannot just install/mount anything.... I guess you need a raspberry or something similar for this ?

[darkrain]

Yes you need at least one Rasberry or a 24/7 NAS with docker at the customer's site where you can install the iobroker.

Hello, I was curious and installed iobroker in a docker container. What a cool system. I am now testing to put that KNX DPT20 through this system. Pretty much for everything that can't be done directly from Loxone, there is an adapter available and you can read in values from Loxone via virtual inputs. However, I have a question : since in Loxone you can only read in values (numbers) and some outputs from the API of iobroker is text, I cannot read them in. Is there a possibility in iobroker to convert those return texts (e.g. status values 'onlin', 'offline') into numbers ('0', '1')?

You can convert stings to int in the iobroker via the nodeRed plugin.
