Hi,


I think I've lost communication between my Head Unit and the relay box.
My basic setup is an RA Plus, single relay box and wifi unit.
I have 3 temp probes and use the two I/o's for sump level safety (float switch) and a little relay to trigger a power out mode.

Last night I heard a relay going berserk. Rapid fire on and off for about two seconds. This would happen randomly.
I checked things out and thought it might have been the float switch giving up on me. I unplugged that and the issue continued. I tried the same thing with relay and it didn't have any effect either. At this point the I/O display on the head unit would not show any changes to the state of the input which was a bit odd.
Power cycling the system didn't change the behaviour.
I connected via the phone app and turned the relay that was freaking out into "ON" mode. Went to bed.

This morning I power cycled the unit again.
I/O on the head unit is displaying the current status of the IO ports correctly.
When I change any relay's to on/off/auto via the phone app, the head unit reflects the changes but no relays respond.
I have a slow flashing "Status" red light

Code is the same I've been running for two years so nothing is different there.
To confuse things, I think the float switch has died and might be adding to the confusion. I'll try swop that out when I get home tonight.

HAVING SAID ALL THAT.....its first issue I've ever had with the unit and it's been rock solid for years:)

Ok,

Haven't been able to check the float switch but if I scroll on the head unit there is an item that says "bus lock"

Edit : original float switch is working. Tested with a new one and all the I/O ports are being read by the head unit correctly.

I read some guys had issues with expansions and getting the bus lock issue but I don't have any at this point.

Dang,

Tried to reboot by pulling the power out of the relay box.
Everything is now dead - no power.
We had a power spike yesterday..... I have a ups between the mains and RA. Do you think it could have been fried by the spike?
Any way to tell?

Looks like water damage somewhere

Hi,
It suddenly settled down so I started migrating gear back onto the Relay box.
I then heard the random relay again.

It would appear to be an issue with the WiFi attachment (water damage or other). I unplugged that and it's running solid for about 12 hours.
Just put it back in and lets see .....
