ZEN15 doesn't report at power interval if zero

[Hubi]

When the frig is on my current is around 0.7A and when it is in standby it is around 8MA so setting it to 0.1Awill achieve what you are recommending I believe... thks

Note that energy is not reported.

You need to understand the difference between energy and power.

energy = kWh (killowatt hours), this is energy consumption over time.
power = watts, this is the watts being drawn right now.

TURN ON DEBUG LOGGING for the DEVICE
Set the POWER reports to 1 minute as a test.
Unplug fridge or do whatever to get it to use 0 power.
Check DEBUG logs.

What are you trying to accomplish anyway...?

Thanks for this thread! I just "upgraded" a bunch of Zen15 devices from 1.03 to 1.06 Firmware, and have been encountering a host of "issues" related to power reporting since then.

Like @HAL9000 I'm using them to monitor sump pumps, an on-demand water heater, and a refrigerator. When on 1.03 the refrigerator monitor worked great. On 1.06 the Zen15 loses it's mind at some point, and while still being "on" stops passing power. Sending it an "on" command restores power.

One of my Sump monitors started behaving similarly after the 1.06 update.

I did flash them, exclude them and rejoin them after the flash (I actually forgot about that initially).

In any case right now, I'm struggling with these things. I have about 8 V2.0's, and one of the new 800 Series (Which seems to work fine). A classic case of "upgrading" firmware when I didn't need to. .

I think I may need to change to @jtp10181's driver for these. I didn't realize there was one!

I'm at work now, but again thanks for this thread -- some of the discussion here may help me resolve the issues with my units!

Makes sense. So it represents the integration time of power to give you energy. What you graphed is Power... that is just I want to do. Can you tell me what you used to graph that out. I am guessing that you are using the Advanced driver and you set the "Power (Watts) Reporting Frequency" in the driver to something like 1 minute? You wrote a custom app to do this right?

No for this plug it is still on the built in HE driver, never had an issue so just never changed it. Most of my Zooz stuff I have on @jtp10181's driver but not this one. It's set for a 10% change or 5 min.

No custom app I am graphing using webcore's built in graph capability.

@jtp10181

@hydro311 Can you set one of your ZEN15 v2 to report power every minute with debug logging on and see if it keeps reporting 0 every minute. (Would require a device that shuts down to 0 power obviously). Or manually set parameter 171 to 10 seconds if you are impatient like me.

Sorry for delay - busy last 24 hours...

Setting P171 to 1 minute with no load and debug results a 0-watt report every minute:

Summary

This Z15 is an 800 model (paired mesh S2) on v2.00 f/w

[jtp10181]

Thanks, so working as expected and same as my (your old) 1.06 model.

BTW, I found homes for them both, one is on my sump and the other is on my Freezer so I can track how many times it cycles. After it was acting up and I almost lost everything in it, I put that on there and a temp sensor inside so I could monitor it.

[hydro311]

Right on! I'm glad they are useful -- they were always faultless for me, so I hope they continue to serve you well!

[Hubi]

I am going to do the same type of monitoring on my frig that you did on your freezer. I just found out the my Aqara (Xiaomi) WSDCGQ11LM temperature sensor looks like it's update report rate is every hour. Can you tell me which temp sensor you used. Does it have a command in which I can force it to report temp when I want? Does it have a programmable frequency at which it reports temp? Thanks

[jtp10181]

I had an extra one of these so I put it in a ziplock bag in the freezer. It reports about every 0.5 degree change, so quite often. You cannot adjust any of its settings like many of the TR devices, it just does whatever it wants. Its very chatty but seems to work good and AAA batteries are holding up in the freezer.

Thanks for the info. Have you any opinions on the Zooz ZSE44 temp sensor?

Jeff,

What sort of Power does your Zen15 measure on your Sump?

My Sump is a 10Amp model, which would imply a max Power of 1200Watts, but I regularly see reports between 2900 and 3K+.

This would seem to be inrush current, but the 1.06 Firmware seems to turn off the switch when it sees this. (Overload?)

On 1.04 Firmware, all was well. Very strange to me.

You might want to have a look at this thread. There are two things at play here. One is that ZEN15s have in the past reported absurdly high values for power .. like tens of thousands of watts. This may have been addressed in a firmware update at some point.

The other issue is the so-called "overload protection". My Bosch dishwasher routinely tripped that, despite it being rated at 12A and being on a 15A circuit breaker. There is no way no how that the dishwasher was pulling more than 16.5A for over 5 seconds. Against ZOOZ's strong recommendation, I disabled this so-called "protection" and all has been well since. It wasn't protecting the dishwasher, or the wiring, or the circuit breaker .. only the ZEN15 itself.

Zooz ZEN15 turns off on its own (overload protection?) with Bosch dishwasher

I've had great luck with ZEN15 power plugs and have one on many of my appliances (sump pump, dehumidifier, washer, etc.). I had one on my old dishwasher for several years. Using same on a new Bosch dishwasher, and it consistently cuts off power to the load early into the cycle. The LED is solid orange. Last event recorded was a new high power reading, but it is only 269 watts. The dishwasher pulls max of 12A and never trips a 15A breaker. Bosch dishwashers don't have a heating element to dry di…

It uses a button battery so it wont fair as well in the extreme cold. Otherwise it is a solid sensor.
Another thing people have done is ecowitt sensors with a probe, but you need a hub for those.

That TR sensor actually is pretty good for it because I can also just see the temp on the screen through the baggie when I open the freezer. So far the cold does not seem to hurt it.

@scottgu3

What sort of Power does your Zen15 measure on your Sump?

Usually it goes right up to ~490w, runs for about 15 seconds, then shuts off.

[scottgu3]

The TR's are great with battery eliminators as well!

This seems like exactly what I'm seeing.

Intersstingly, the symptoms are worse on Jeff's driver, as the load protection is triggered when it gets an absurdly large reading, and on the built in driver it doesn't.

No idea why.

I've got a bunch of the Zen15's, mostly version 2, with FW 1.06/1.6, but at least 1 800 LR with fw 2.10 as well.

Time for some experimentation!

The load protection is in the firmware, so this is pretty much impossible unless there is a setting that was changed which is impacting it on the device for some reason.

If you know the device is not over-drawing just disable the overload protection as others have said. If it really does over-draw it should pop your breaker anyway (assuming 15A circuit). Worst case the ZEN15 would get fried in that situation.

For the 800LR model on FW 2.10 they have added some new settings to prevent false alarms, I think I added them to my driver (will only show if you have proper FW).

I 100% agree that this should be true. I can't explain it.

I've got one 800 LR Zen15 and I probably still have one or two with V2s non 800 with 1.3 or 1.4 firmware to play with as well. And I'll try to use a different brand of plug to get a "real" power measurement, as well as look a the current measurements on the various Zen15's.

Honestly, since I updated the firmware on these v2 1.x models I've had nothing but trouble, and I doubt the driver is the issue on any of them.

I'm thinking "this is the way" although I don't like it a lot.

Thanks Jeff!

Thanks for sharing this -- I was thinking about updating mine from 2.00 this weekend, but I'll hold off on that.

[jtp10181]

@hydro311 he is talking about updating from 1.x to 1.06, not the 800LR with the v2.x FW
