FHT80B-2 will not pair with FHZ1300PC

[fredd500]

Sorry for my lack of German. I am English, but try and speak a little Spanish.

I have 5 FHT80B's, a mix of -2 and -3 versions from various suppliers including ELV, Conrad Electronic and EQ-3.

I have been having lots of issues recently with them unpairing from their actuators so I have taken them all in to one room, changed all the batteries and tried to re-sync them both to their actuators and to FHEM. So far so good, for the last few hours, four of them have been communicating well and remained paired. One of them however will not pair with the FHZ1300PC. I have set the FHTcode, put the FHT in pairing mode (Cent -> nA) and issued a couple of commands (set FHT_3f2d desired-temp 19.0 and set FHT_3f2d report1 255) but nothing seems to work. I just receive start-xmit: 100 and some actuator messages. Nothing else.

Can anyone help me with pairing this FHT to my FHZ?

Many thanks
Chris

Is your fhem up-to-date? Recently I've had some Problems with my FHTs, too. After having done an update everything is fine again. Please type "update" in the command field, wait until the update has finished, restart fhem and try again.

Best regards

FHEM has little influence on pairing an FHZ with an FHT. According to my experience an FHZ will agressively try to pair with any FHT advertising itself as "free" (i.e. sending start-xmit: 100), there is no need to send any FHEM commands. Important: This is only valid for the FHZ, but not for the CUL.
There were certainly no FHEM changes regarding this in the last years.

Yes, FHEM completely up to date - new install in fact, but updated using the update command just to be sure. I'm seeing (or was) the start-xmit: 100 messages, but nothing else from that particular FHT. All others are reporting status including actuator %, window status, battery status etc regularly. The FHT that isn't reporting seems to be talking to its actuator and the interlock OK at the moment so it does't seem to be general radio issues unless they are with the FHZ, but given that other FHTs are reporting OK, I suspect this isn't the case? I was having all sorts of problems with actuators loosing their FHTs, the interlock not getting updates etc. I seem to have resolved that for now by changing ALL batteries throughout the whole system (some were originals of some years old!) and re-pairing everything. The one remaining problem is just the one FHT not reporting in to FHEM.
