Recirculation always on

[guillochon]

Describe The Bug: My water heater seems to be perpetually in "recirculation" mode. In the Control-R app it always shows as "recirculating" and in Apple Home the device's status is always on. If I send an off command, the Home accessory shows as off for a little bit (maybe 10ish seconds), but immediately flips back on. The heater itself is not recirculating in this state, however when I power cycle the heater it immediately starts recirculating. It then will not recirculate again until the next power cycle.

It's entirely possible my heater is just in a weird state but it's strange that my attempts to turn off recirculation after power cycling are ignored.

Logs:

This is mean trying to toggle the heater off, those attempts are logged. I don't see anything else in the logs.

Can you try cutting power to you Ctrl-R device for a few seconds, then restoring? I have noticed that mine occasionally goes unresponsive. In fact, I ended up putting my water heater on a smart plug, and creating an automation that cuts and restores power every day. Sad, I know.

I wasn't aware there was a way to cut the power only to the control-r unit, for me it's hooked up to my heater via a pair of wires...how do you do that?

I mentioned in the OP that I tried power cycling the whole heater (which includes the control-r unit), but that didn't work to get it out of its funky state.

I did seem to get it back into a working state by taking off the front cover of the heater and toggling the on/off button for the temperature controller. But that's super inconvenient as you might imagine...why they buried those buttons behind the front panel is beyond me.

[dustindclark]

If you cut the power to the entire unit for long enough (10 secs or so), the ctrl-r loses power as well. I know it's an inconvenient solution, but there's no way around the Rinnai firmware. Clearly their server-side stuff is plagued with similar problems.

Closing as issue appears to be resolved. Re-open if that's not the case.
