Unable to pair HM-SEC-SCo

English Forums Hardware

Hey Sathya,

I just got a package containing some new HM devices. Unfortunatly I see to be unable to pair the “new” HM-SEC-SCo with my Homegear Setup.

Should this be possible or is HM-SEC-SCo currenty incompatible?

Do reduce some possible problems I have disconnected my HM-CFG-LAN devices and tried it using the COC only.

Here is some logfile output that I think happened during the time I pressed the “Teach In” button.

The HM-SEC-SCo’s LED went yellow and then green, but the Configurator still says “No new device”.

I have solved it myself. It seems as if eq3 configures the HM-SEC-SCo with AES on by default.

I had to pair it with my CCU2 change the AES setting to disabled. Unpair it (without factory resetting the device) and then pair it with Homegear successfully.

Hey Chris,

yes AES handshakes are mandatory for the HM-Sec-SCo to work (see [1]). Actually I’m surprised it worked the way you did it, because I thought it’s always necessary for pairing :wink:. You could’ve paired it through your HM-CFG-LAN’s, too.

I do have the same problem with paring HM-SEC-SCo.

It can be paired with the HM-CFG-LAN, but not with the CUL.

I found in this thread the hint, that it is neccessary to change from secure mode to standard.
I tried this several times, on the HM-CFG-LAN, it is now to Standard.
But if I delete there and try to register with the Homemeatic config tool on the remote RPC it is still not registering.
I have the feeling,that if I bring the device in register mode, it always default to the secure mode.

I have also an HM-SEC-SC, this is registering fine with the CUL, but I prefer the other device.
It has a standard battery and is smaller. I do need about 15 of this devices, so currently I’m just in the testing phase.

Any other proposals how to get the device registered?

Hey,

if you delete it, you need AES handshakes to pair it again. To get it to work with the CUL you need to pair it using the HM-CFG-LAN, disable AES and then use the RPC function “setInterface” [1] (without unpairing it!!!) to switch to the CUL.

Cheers,
