Hi,
I don't know when it started but my integration stopped working due to two error messages:

1. New state 'FILTERWECHSEL ABLUFT' for 'BETRIEBSSTATUS'!
2. "Ungültiger JSONata Ausdruck: Unable to cast value to a number: "28.3°C"

I didn't change anything on my system but it could be that my ISG was automatically updated since I was in contact with Stiebel regarding my access from outside my network to the ISG.
The first error message I think is because I need to change the filters. The second error applies for all values and I don't know why. Would be really great if you could look into this. Thank you in advance.

Hi,

first of all here is my setup:

1. I use Home-Assistant Core on a Raspberry Pi 4
2. the MQTT broker is running on my NAS
3. I am able to sent and receive messages via MQTT (I use it already for other things)

My problem is that if I connect for example with MQTT.Fx (Windows Client) to my broker, subscribe to homeassistant/sensor/# I can't see any message regarding the heatpump. HA also does not discover the device automatically. If I use HA to subscribe to homeassistant/sensor/heatpump/# I do see messages coming in. Any idea why I don't see the messages outside of HA and why the discovery won't work?

can you please add some brief notes or links on how to use this? I am very interested in using this module to read data from my heat pump, but I am not that experienced with Node-Red and don't know to get started. I have managed to configure my HA instance with a bunch of sensors.

Hi,
I am not reporting an issue. All is working :-)
I updated the flow to support the LWP 10 I from SE (2013). As it uses Air instead of Sole or water the Menus has less values to read out. Some values have duplicates like "Solltemperatur" (5 times) ;-) I used therefore the flow-ServiceWelt-Tecalor-TTC05.json as basis. Should we integrate my flow into this repository?

Hello,
I installed ServiceWelt Tecalor flow, configured my ISG and I can't get through this error in the CONVERT To NUMBER cell with this error message:
14. 1. 2022 21:58:19node: Convert to number
msg : string[73]
"Invalid JSONata expression: Unable to cast value to a number: "87.496kWh""
I also tried the variant where I exchanged the dot for a comma in the number, but it ends with the same error voice.
Can you help me, please?
Tnx. Tomas
