Using WiFi with a Z21 and automation is always asking for trouble because the Z21 protocol is UDP and as a result data often gets lost. This is not a problem when using a throttle because the command is repeated regularly. An occupancy sensor message is is different from a throttle.
You are better using LocoNet over TCP, however that is not available from a Z21 and the only way to ensure that the messages are not lost, or significantly reduce the possibility of it being lost is to use a wired connection between the PC running iTrain and the Z21.

Thankyou for your response; it looks like we may have two problems but I can see they might be related.?
The 1st issue discussed at the start of this thread were two false feedbacks that occurred on two YAMoRc units during a show that we were unable to clear by resetting, turning off and on etc. I am unable to repeat this issue.?
The issues yesterday and today, have occurred on a DR8088LN box and as you say are better described as stuck feedbacks rather than false ones.?
We are using a Z21 black control station connected to iTrain via wireless connection to the a router which has a network cable to the Z21.? Vehicles and feedbacks are all handled by the Z21.?
Z21 Loconet has:
- DR4088LN connected to a DR4088 via S88
- DR4088LN
- YD6016LN connected to a YD6016ES via S88
- DR5088RC
?
We use a YD7001 to manage the accessories on a seperate bus.?
we have been running the layout with setup for a couple of years with very few issues.?
The biggest problem in finding the problem is that we can run the layout for several hours with no issues before a problem occurs. But when a problem occurs at a show it can be disastrous, and really embarrassing.
Thanks again for your comments.?
