I use the Comfort-Homeseer connector to get pretty much all events in comfort being reported to Homeseer. Seems to work pretty well. I have an event being trigerred by phone hook-swich state changes.
When the phone goes off-hook my off-hook event fires as expected.
When the phone goes back on-hook at the end of the call, my on-hook event fires as expected. - But, is then immediately followed by another off-hook and on-hook sequence in quick succession e.g.
OFF-Hook event fires
time passes while the phone call occurs... the call ends...
ON-hook event fires, OFF-hook event fires, ON-hook event fires.
Any idea why this should be?
Cheers.

We have tested this here, with an Output switching on when the phone goes offhook and switching off when the phone is onhook
We dont see any repeat occurences when the phone goes either onhook or offhook
This may be a case of there being some bounce in the onhook relay in the phone, perhaps after some wear (if it an older type). Try it with another phone

I had to hunt around to find a phone that's not part of the DECT system, but that appears to exchibit the same behaviour.
Other than this test one, all my phones are DECT handsets running off the same base, since the pickup/hangup from the handsets is just a soft button sending a signal to the base, surely there's no scope for relay bounce?
Is there any further testing I can do or tuning parameters I can adjust to reduce the sensitivity of the hook-detect? - it's annoying since I want to use it to automatically record calls on our landline.. - it means I get a redundant 1 second long WAV file cluttering up the recordings folder for every genuine recording... - I also get double announcements via TTS to various places..
Cheers.

Your DECT base station is connected to Comfort TEL Out?
Are there other phones connected directly to TEL out as well?
When you tried the non DECT phone, did you disconnect the DECT from the TEL OUT? Try the non DECT phone with the DECT base station disconnected
The DECT base station may be responsible for the doubloe signal, not the handsets, as the relay would be in the base station, not the handsets
There is no adjustment of sensitivity for this, when Comfort detects ON hook the ON hool response is activated and vice versa. The fact that it is happening again means that it is detecting such an event

Ah yes, good point, - from memory, I believe TEL OUT comes out to a block of 8 commonned ports on a patch panel, but there's definately a BT socket there as well, with a local wired phone hung on the wall next to comfort for testing purposes & recording announcements etc... The telephone line recording device is plugged into a socket on the outside line (i.e. before the line goes into TEL IN).
I'll need to go & refresh my memory of exactly how it's all wired up. I should be able to remove the internal phones without too much difficulty, then test with individual phones attached.
Thanks.
