I am not integrating with Alexa yet, however I think once you have the OpenHAB skill setup and you can control the fan from OpenHAB now that this should as well work via Alexa:
Why would you do that via Alexa though? There is 2 reasons to adjust fan speed: outside temperature (you do not want to get the hot air in summer into the house) and air quality (which you could measure with NetAtmo modules which have built-in CO2 sensors).
A third could be noise - but if your system is correctly configured you should not have annoying noise.
Hi,
I want to put the levels 0,1,2,3 with Alexa. alexa needs a switch, but a switch has only two states. So I need 4 switches, each with a status (0, 1, 2, 3). Or do you have another idea?
it seems these are not compatible with the ISG Web interface which is needed (or recommended, I think there was a guide on the web to create your own serial adapter, too).
You can check out the ISG docu if you find references to supported devices:
Iâm trying to set the warm water temperature in the modbus stiebel isg binding - default name water temperature set point - but if I enter 37 (for 37°C) it shows a few seconds the value, but falls back to the currently set valvue (44°C in my case) and is not transmitted to the ISG.
In the former version (modbus without stiebel extension) Iâve transmitted 370 (due to the data type) - that worked.
What do I need to do to get it done with the new official binding?
But what in Detail do I need to send? I tried various values,read once again the Stiebel ISG modbus pdf, in case I miss something�
Please advice,
thanks, Christian
@Pinocchio could you kindly share your adjusted âthingsâ and âitemsâ file for the LWZ Modbus Binding to work properly in OH4 I am about to do the upgrade finally
I changed mine from setting the transformation at THING level to items level: Example
Of course I do have the transform scripts in the /conf/transform folder. I tried as well âtransform:JSâ without success. Maybe share your transform scripts, too - that would be awesome.
