Strange temperature-readings

[jk-andersen]

Hi,

first of all: This is awesome - All of you guys participating and really printing boards and software for a 15+years heating-control. I absolutely adore this.

I got the board from Daniel and played around with it a bit and get some strange temperature-readings.

---

Temperature-Readings are junping 255 to 1 or 2 Degrees I am not a pro in the depths of this code but maybe this has to do with my heating system not beeing oil, but a Gas-Heating "Logano G144" ? I flashed the newest version of the git today.

Any idea on your side? Cheers, Jan

EDIT: Als Nachtrag: Auf der Geräteanzeige werden mir -2°C für den Aussensensor angezeigt. - Rechnet mein Wert nicht sauber in HA (0-2 = 254?)

Hi @jk-andersen and welcome to the project! The temperature reading as it is at the moment can't deal with negative values. I didn't notice it yet as it was not that cold here ;-) I've created a pull request to fix it here: https://github.com/the78mole/esphome_components/pull/15 So if you like, you can use the code from there branch or wait until it's on the main branch - which should be tomorrow or the day after.

Hi there,

I recompiled and flashed now after the merge but still get the same results, also for #18 I am new to the ESP-Flashing game but I think I did it right as I was able to add some new sensors. I got a compile error though in between (full log attached):

Mh, that's strange - with the merge to main both issues should be fixed. The compile message you see is a warning that's originating in code from the ESPHome base code. It's not pretty but it's also nothing to worry about and should not affect our issue here.

I checked the ESPHome manual: If not specified differently, ESPHome only checks once after 1 day whether a github repository has changed: https://esphome.io/components/external_components.html#refresh -Maybe that's the issue here. You could try adding refresh:3600s to the configuration of the external component - or wait some time - and see whether this helps.

One other thing: Strange readings for "Abgastemperatur" are to be expected if your heater does not have a hardware sensor for the exhaust temperature installed. My heater for example, doesn't have one.

I add refresh: 0s ... so every time it is compiling it refreshes the sources... :-)

Thanks a lot - that helped and now I have beautiful -4 degrees of Celsius there. I actually checked and there is no exhaust-sensor in my heating, so thanks for the tip there! Really appreciate your help!
