I'm trying to understand the logic of the MQTT messages for the POW. It's sending a message approximately every 2 seconds while the washer is going and ignoring the logging period set in the MQTT page. It's not a problem as such I'd just like to know how it decides when to send a message. I've read the threshold section but I'm not sure that helps me. The POW page says the preferred method is the push and will send a message every 5 minutes if set to 300. Console doesn't show any status requests so I'm not sure why it is sending so many messages.
I downgraded from 6.1.1 to 5.14 to see if it changed anything but doesn't seem to.
(Please, remember to close the issue when the problem has been addressed)

Set PowerDelta 0 - see Wiki for details

Thanks. It may be helpful if that was on the POW page of the wiki as the behaviour is different to what it states on the page. I couldn't understand why the immersion heater wasn't doing it but the washer was. The immersion is steady state but the washer is constantly changing with motor restarts and water on/offs.

I've made a note on Pow page
