avm plugin -> hkr_device -> set_temperature

[giase82]

Hi,

Thanks a lot for this plugin, very helpful!

I am trying to integrate my Fritz!Dect 301 Thermostat, and am using the hkr_device-functionality. Reading state and temperature works fine, however, I would like to be able to set the set_temperature. It seems this is currently not supported?

Could this be added?

Best regards,

Hi,
setting the set_temperature is already implemented but not released yet to the master branch. Just use the pluging from the develop branch:

Hi,

I just tried that out but it hasn't been successful. I tried setting the set_temparature with Visu (and from the Admin-page), but with every "update-loop" the previously set value is overwritten. So it seems it is not written into the thermostat. Please see the log-extract and config below.

I'd be glad to receive hints and would be happy to test!

I found a hint in the warnings-log:

Do you have an idea what is wrong? Why can I read but not set? User-permissions in the FB?

Hi again,

I figured if I reset my FritzBox to use the standard 443 port, it works. I am confused as reading the temp is working also before. How is the port for the FB-interface for the plugin derived? e.g. if I use the standard FritzBox-port 443, the plugin port is 49433. What if I e.g. use port 44450?

[psilo909]

49443 is the standard HTTPS tr-064 port (e.g. https://www.janrufmonitor.de/tr-064-aktivieren/, https://avm.de/fileadmin/user_upload/Global/Service/Schnittstellen/AVM_TR-064_first_steps.pdf -> Chapter 3.1)
please ask AVM how to change that and not us. if it is possible to change it at all!

[giase82]

I just meant to say: If someone does NOT use the standard HTTPS port for security reasons in the FB (as I did), the avm-plugin won’t work as expected. This should be helpful information for you as well.
In addition, it might be confusing to allow setting the port in the plugin to an arbitrary value as this implies that this should work.

This particular problem here can be solved setting the standard https-port in the FB.

Cheers!

it is ok to switch the port between http and https. so at least for this it is mandatory to have it configurable.

i cannot say how TR-064 will react if you reconfigure 443. but i suppose there is a solution as AVM is also using their TR-064 interface. if they did not regard a changed 443, this could be also a bug in the fritzbox, but its not upon me to judge.
