DPT14 for thermostat

[deejonz]

I have a thermostat which returns the humidity only in DPT14 (generic 4 bytes float). Is it long to implement this? What's the file to modify in case I want to try implement it?

[deejonz]

@snowdd1 any help on this?

[snowdd1]

If I find time I will have a look at the 4 bytes float type, I didn't need that type so far and don't have a device that supports it.

Thanks Raoul,

if it can help, I can share you privately my KNX ip address and the related group address which returns the 4 bytes float values.

Thanks.

Hi @deejonz
I found out the library I use for connecting node to the knxd does not support 4 byte float (yet).
As I do not have the time to add that right now you might ask the author of node-eibd, @andreek, to help you, or you fork that repository and implement support for 4-byte-float types yourself.
Regards
Raoul

Hi, thanks for your time. I will ask Andreek if he can help. Regards. Stefano.

Hi @farmio have you had a look at my (abandoned) project to have a generic DPT parser implemented in nodejs?

https://github.com/snowdd1/knx-dpt-parser

If you are interested you might inherit that package, I do not have the time to work on it right now and bring in a productive state.

@snowdd1 Hi! I kind of have my (abandoned) project myself. I extended node-eibd with a handfull DPT encoder / decoder and a function to assign a specific DPT to a GA: https://github.com/farmio/node-eibd/tree/dpt-memory

A nicely documented DPT parser is also https://github.com/Rafelder/knx-datapoints

I haven't looked further into merging this projects as I found that https://github.com/XKNX/xknx seems to work a better than knxd in my environment.

any progress on 4 byte? would like to use it for power consumption,also can u add service PowerMeter type and Characteristics type Watts and KilowattHours? From https://github.com/sprut666666/new-types-for-homekit

knxd reads it with no problem knxtool groupreadresponse ip:localhost 4/7/2 Send request Response from 2.1.29: 44 01 95 1F

@deejonz are you still looking for handling dtp14?
