[Solved] Problems setting temperature of HM-CC-RT-DN

Hello,

I have problems with my radiator valve. I got it paired with homegear. The time and date is automagically set and the actual temperature is also received:

However, I’m not able to set the temperature. Homegear shows the following error:

The device is also shown with “Config Pending”. Pairing again or resetting the device does not help.

Any hints what is wrong with my setup?

Hey Sven,

sorry for the late reply. Now I had time to test this. I experimented with the LGW communication and there was an error in some nightly versions. Could you recheck if you still have the problem with the current nightly version? Here it works now.

Cheers,

Hello Sathya,

now appologies from my side for the late reply.
I tried to compile the latest git-version using the Arch Linux package: aur.archlinux.org/packages/homegear-git/

However, I get the following error:

In file included from DeviceDescription/HomeMatic/HmPhysicalParameter.h:35:0,
                 from DeviceDescription/HomeMatic/HmPhysicalParameter.cpp:31:

  void memcpyBigEndian(std::vector<uint8_t>& to, const int32_t& from);

And so on…

Any ideas?

#4

Adding #include solves the error. However, than I get the following:

HelperFunctions/HelperFunctions.cpp: In static member function ‘static int32_t BaseLib::HelperFunctions::getRandomNumber(int32_t, int32_t)’:
HelperFunctions/HelperFunctions.cpp:164:2: error: ‘random_device’ is not a member of ‘std’
  std::random_device rd;
  ^~~
HelperFunctions/HelperFunctions.cpp:165:2: error: ‘default_random_engine’ is not a member of ‘std’
  std::default_random_engine generator(rd());
  ^~~
HelperFunctions/HelperFunctions.cpp:167:22: error: ‘generator’ was not declared in this scope
  return distribution(generator);
                      ^~~~~~~~~
HelperFunctions/HelperFunctions.cpp: In static member function ‘static std::vector<unsigned char> BaseLib::HelperFunctions::getRandomBytes(uint32_t)’:

  ^~~

   bytes.push_back(distribution(generator));
                                ^~~~~~~~~

So I guess the root of this problem is anything else…

#5

Some other includes were missing. I created a pull request:
github.com/Homegear/libhomegear-base/pull/1

#6

Please also consider the following pull request:
github.com/Homegear/Homegear-Ho … CoS/pull/2

Finally, I have the new version running and can confirm, that setting the temperature is now working!
Thanks for your great work.

Thanks for the pull requests!
