I’ve already posted that request in the German forum but think I get a wider audience here
Now that I have familiarized myself a little bit with Homey, I would like to realize the following:
I have a Novelan heat pump that runs a web server. This server provides a Java web interface (Luxtronik), on which various data is displayed (e.g. temperatures, pressures etc.) and also certain parameters can be set (e.g. flow temperature, heating curve, heating/cooling mode).
I would like to see some of the data in Homey, e.g. as virtual temperature sensors, and would like to change settings.
Is there already an app that can be used to read such data?
I would appriciate this. But I’m afraid I can’t help.
As far as I know, the heatpump`s web server uses the websocket protocol.
An app would have to call and send data from/to the webserver via websockets.
Some information can be found here: Websockets Webinterface (ab FW 3.81) - loxwiki - loxwiki
If we could - together - find a starting point I would like to contribute and test.
Hi there, sorry to be a little late to the game but I would be very interested if there was some progress regarding this topic. I use a Alpha Innotec Heatpump and would love to set the parameter starting by some triggerd flows.
So. I actually have a proof of concept working (only for the getting). I am debating if I should implement setting of values as this is a bit hit-or-miss and some things aren’t properly documented.
Any specific values/functionality you’re interested in?
Sounds great! For the getting functionality, I suggest including temperatures such as flow temperature, outside temperature, and source temperature, as well as the flow and operation mode states. When it comes to setting values, consider implementing functionality for selecting the operation mode (heating, cooling, or water) and specifying the target temperature for heating.
Currently it only supports reading values; Ill try to work on setting values, as well as improve the reading (e.g. more values, and improve the values that are model-specific).
Furthermore, I am looking forward to any feedback as i was only able to test this with 2 models of heat pumps.
Hey @RobinF ! That works very well for a 1st attempt. I was able to add my Novelan WSV 6.2K3M heatpump without problems. All the shown values seem to be correct and update nearly in realtime. Despite some localization issues (mix of english, german, dutch) it works well for me and I#m looking forward to seeing further developments.
Hi there! I’ve been trying to connect the same heatpump model as @petomei, but cannot get it to send the data to Homey. I can see the pump registered in homey as a device after registering the IP address, but am not receiving any data. Any chance you can advice, @RobinF? Much appreciated!
Assuming the IP is correct, it just tries to connect to port 8889 (don’t quote me on that, not at my computer ATM).
Then it just queries different parameters.
@petomei, I should also have fixed most translation issues. While there’s no full support for German yet, all strings should be English, Dutch and some German. So you shouldn’t be seeing Dutch anymore.
I’ll try to sort the German strings out, maybe I’ll ask a few things
