jillelaine01ParticipantOkay, hive mind, that is happening here? I believe this is a firmware issue, having taken the steps to eliminate other causes.
Background: I have two controllers: a remote controller (Hardware v3.0 – AC) with 24 stations (configured as an extender), and a ‘master’ controller (Hardware v3.2 – AC) with 40 stations including the 24 remote ones. Both controllers have the latest firmware v2.2.1(1) and are on my local wireless network.
Everything works very well EXCEPT two remote stations: stations 5 & 6 on the remote controller.
With ‘Special Station Auto-Refresh’ enabled on the master controller, remote stations 5 & 6 ‘pulse’ on & off at regular intervals. Typically the station will turn OFF after 47 seconds and turn back ON 25 seconds later. Please see screenshot of logs from remote controller. With ‘Special Station Auto-Refresh’ disabled (Off – unchecked), the pulsing does NOT occur. Again, with ‘Special Station Auto-Refresh’ enabled (On – checked), the pulsing always occurs BUT ONLY WITH TWO of the 22 remote stations, stations 5 & 6.
(Note that ALL control is done from the master controller. I use the remote controller ONLY to monitor the logs. The master controller’s log is blissfully unaware of the on-off pulsing of the station.)
I’ve done many tests and this behavior is reproducible always, but with stations 5 & 6 only. None of the other 22 stations on the remote controller pulse like this, regardless of the setting on ‘Special Station Auto-Refresh’.
What I have tried: added a new access point closer to the remote controller in case the pulsing was related to wireless signal strength (made no change), updated the firmware on both the remote and master controllers to 2.2.1 (1) (made no change), and swapped the wires between station 5 (pulses) and station 7 (doesn’t pulse) to eliminate any possibility that it is a ‘downstream’ wiring issue between the controller and the valves. Swapping the wires between a pulsing station and a non-pulsing station produces no change: Stations 5 & 6 ‘pulse’ (with ‘Special Station Auto-Refresh’ on) regardless of which valve they address.
This is likely a very specific firmware issue with how ‘Special Station Auto-Refresh’ is handled on the remote controller for the two stations 5 & 6. Any thoughts?
