Need To Know When My 220V (US) Dryer Is Done

in the breaker box.. not a big deal especially if not putting the clamp on the mains. as you can shut the main breaker off and just put it on two of the wires going into the dryer circuit.

i also have another unit on the mains to monitor the whole house. that is a little more hairy

I have a feeling that these clamps are a LOT smaller that I am imaging so I might have to give it a try. The phone idea above in the mean time is a cheap and dirty solution that seems to work OK... I just hope one day I do not see my phone on the floor from being vibrated off the top of the dryer! LOL

Thanks for the info

I've had one also for several years, at the default reading rate of once every 5 seconds.

Which Hubitat driver do you use for the Aeotec DSB28-ZWUS... or do you just use the Zwave device that is created after device discovery?

FYI - there are other options to monitor 240V power consumption for an appliance like an electric dryer.

What got me interested in the Aeotec DSB28-ZWUS is the price on Ebay --> $25. So I thought I would give it a try. Just wanted to make sure it works in Hubitat. It is recommended here but was interested in if it works with the standard driver you get when you discover zwave or Hubitat has something else I need to know about for it.

Mine was a little tricky, as I recall.

That's a 300-series z-wave device. And can be chatty. Aeotec does make a z-wave+ version of it as well.

These are the drivers i use; one built in for whole house power and the other (user) for dryer monitoring.

Could you point me to the source code for the HEM driver... Thanks

Long shot, but still have this switch for sale?

I have one I'm not using, PM me if interested

I messaged you.

put a new version of my code for this app up there with the following cleanup/modifications

/*
Custom Laundry monitor device for Aeon HEM V1

  • 3/25 modified by lgkahn add preferences to enable either dryer or washer tracking and check so as not to do extra send events
  • also check current dryer and washer state so as not to send extra on events when already on so as not to trigger extra rule firings.
  • also add dryer and washer ignore watts setting default 15000 so as to ignore eroneous data.
  • also updated fx to dump out status when saving preferences. Also add missing voltage update before washer/dryer turn off so you can see event.
  • also fx to turn off debug logging after one hour

You might consider a battery powered temperature sensor attached to the vent pipe exiting the dryer. Once dryer completes cycle the temp at this sensor should rapidly fall..... A bit safer than messing around with mains wiring.

you dont need to do mains you just need to put one set of clamps around the dryer circuit breaker wires.. easy to do as you can turn the main off first. or you can even put them around the wires coming out of the dryer as most dryers you need to wire in a pig tail anyway as they are not included as outlets vary,

probably actually less work than trying to tap into the vent pipe and not have a leak or swap batteries in the sensor, and in addition probably not reliable say for low heat delicate loads etc.

another option i tried is a shock sensor and that also not reliable for me.

Have you any pictures of this? Just curious if you put it right on the vent pipe, Shouldn't be too hot for a sensor eh?

I've had my ZSE44 up to 165.3 F over a wood stove, and it was not maxxed out.

Has anyone tried a sensor IN the vent pipe?
Maybe some rule using a combo of temp and humidity?
