Have any of you had sites where Zigbee doesn't prove to be reliable? I've got a basic system I am controlling all Zigbee. The base station sees the commands, but doesn't output any IR. I have all my devices set to output on all ports and am using feedback emitters, a mix between Xantech and URC, but don't see them show IR being processed. It probably works 10% off the time. If I change programming from Zigbee-IR everything works fine. I've already swapped the remote 3 times, and the base station 3 times. I'm stumped. Any help?

Was the MAC address programmed, or discovered?

Yes and yes

Any particular reason you are outputting all devices from all ports?
The MRZ260 has truly discrete outputs from the individual ports, unlike the MRF260. I would try setting a single device to a single port as they recommend before calling for another RA.

I had IR routing set and when that didn't work I ditched it in favor for all ports.

I've also been having similar problems with my 880/260 zigbee set. Have yours been affecting all devices or only some?

For me, I've noticed it being certian commands/devices. Significantly more common on learned/hex codes.

The only thing i have found to help was to try alternative codes for problem codes. Meaning, if you have a samsung tv, try similar codes from other samsung tvs.

EDIT: just to be clear, the 'problem codes' work perfectly by IR, and do not necessarilly cover the whole device. the main codes for my tv worked, but the discretes i found here would fail by rf only. Different discretes in the database worked both ways

I have installed 2 of these systems. Both are working very well. The only complaint I have, is that you can not convert an MX-880 file into the MX-880z program. So you have to start from scratch which is a time killer.
