Wrong State Value - DPT 3.007 Dimming Control

[Videonisse]

I get errors in the log when manually dimming a KNX light. The GA uses DPT 3.007 Dimming Control.

Log says: "State value to set for "knx.0.Belysning.Dimmer.Kök_Lampgrupp_Pendel_fönster_Dimra_Upp-Ner_4bit" has to be one of type "string", "number", "boolean" but received type "object"

ioBroker v 3.3.18 KNX Adapter v 1.0.45

Raw Object Data for the Datapoint:

{
  "_id": "knx.0.Belysning.Dimmer.Kök_Lampgrupp_Pendel_fönster_Dimra_Upp-Ner_4bit",
  "type": "state",
  "common": {
    "name": "Kök Lampgrupp Pendel fönster Dimra Upp-Ner 4bit",
    "type": "mixed",
    "role": "value",
    "read": false,
    "write": true
  },
  "native": {
    "dpt": "DPT3.007",
    "address": "4/7/137",
    "addressRefId": "P-095B-0_GA-57",
    "statusGARefId": "",
    "actGARefId": "",
    "objRef": "O-111_R-1756",
    "devName": "M-0048_A-493A-1C-D4B1",
    "devInst": "P-095B-0_DI-16",
    "objectSize": ""
  },

Is this a bug, or do I need to change my config for those data points?

This is no bug or error. dpt3.xxx is 4 bit. the 1st Bit means the direction and the bits 2,3,4 are the stepwidth. you can send a state as [a,bcd] with a as 1st bit and bcd as bit 2,3,4 a number.

Thanks for prompt response. Ok, confirmed what I thought.

But what is then the cause of the errors in the log and how can I get rid of them?

[Garfonso]

you could try to change the "type" from "mixed" to "object".

[Videonisse]

Thanks for the suggestion. Unfortunately, it didn't help. Now I get another error message:

State value to set for "knx.0.Belysning.Dimmer.Kök_Lampgrupp_Pendel_fönster_Dimra_Upp-Ner_4bit" has to be stringified but received type "object"

[Videonisse]

I changed the type to "string" and now it works without the errors in the log.

However, I deleted to datapoint and re-added using project import. Then the type is automatically set as "mixed". I assume this is not correct and it should be "string". Is it then a bug with project import regarding how DPT 3.007 Dimming Control is mapped?

State value to set for "knx.0.Belysning.Dimmer.Kök_Lampgrupp_Pendel_fönster_Dimra_Upp-Ner_4bit" has to be stringified but received type "object"

Interesting... hm. Is this with admin 4 or 5? Or a script?

AFAIK the knx adapter sets mixed for many datapoint types. This should probably be changed here, yes.

[Videonisse]

I use Admin v 5.1.25. Value is changed using a KNX push button (dim up/down).

I think the problem is that someone directly tries to insert an array or object into "setState". This dfo not work. Update JavaScript Adaoter, then it should be handled automatically.

[Videonisse]

The DP is currently not used in ioBroker, so there are no scripts involved. Anyway, javascript installed is already the latest I believe (v5.2.13).

[chefkoch009]

DPT 3.x is normally 4-Bit. Lets say it is "xxxx b nnn" where x is ignored, b is a binary for direction (up/down) and "nnn" is interpreted as number with 3bit that means 0-7. The number is the stepwidth.

[Videonisse]

So will you change in the import so it's not created as Object but as Number?

[chefkoch009]

Well, this is an argument, I will fix it.

[chefkoch009]

Seems to be a little bit more tricky, than i thought :-(
