New Zooz ZEN75 Heavy Duty Switch

Affiliate / Referral link (Price on link banner is wrong not sure why its doing that)

New heavy duty switch for large LED loads or fans (on / off only)

Zooz has tested this with my Universal Switch driver and it works well with that for now, all settings are discovered and configurable: [DRIVER] Universal Z-Wave Drivers (Switch/Dimmer)

I will add official support to the Zooz Switch driver when I update that package.

Nice! Just ordered one up for the ol' garage where I've always been a bit over the recommended load for my Z71 -- never had an issue with that, but better safe than sorry.

It will be awesome to get this one added to your switch driver for using the setLED command.

Thanks for letting us know about this - this is a good move by Zooz, as this (large load) has been device gap until now.

Your link had 20 bucks for the switch unfurled, but the site has them for over 30. Still a decent deal. But I clicked it hoping for 20 bucks :wink:

Yeah I saw that I have no idea why the forum is making the link show $20, I just pasted the link and the banner gets automatically generated...

Nice that they have a higher power switch option though for places it can be used!

Rant:

  • Operating Temperature: 32-104° F (0-40° C)

LOL that wouldn't work for pool pumps in Texas, where the switch is almost always outside. It was 96F yesterday, and it is only March. And it gets below 32F every winter too...

I've complained to Zooz a few times that their published temperature ratings (if real) are too limiting. Although their ZEN05 is MADE for outside and it says 32F-104F... So it is likely that the specs are bullshit anyway.

Unrelated (?) but their latest temp/hum sensor won't go below 0° F.
edit: Got it to 165° F, but that's not the upper limit. Didn't continue testing.

Yea, their faq puts the issue on the zwave chip specs.

However, the specification of the Z-Wave chip requires environments of no less than 32 F and no more than 104 F. This is why we list the operating temperature at 32-104 F; the same applies for all Z-Wave sensors and switches we know of since they shouldn't be installed in environments that often drop below 32F or exceed 104 F. It's likely that you may lose Z-Wave control during super cold periods

My detached (and unconditioned) garage here in MN can see seasonal temp swings from 100+ to -20... For many years, I've had a variety of smart stuff there -- Caseta, Hue, Aeotec, Zooz, Yale, etc -- all a mix of ZB, ZW and ClearConnect. All of those devices have worked flawlessly out there, except one...

And that was an Inovelli Blue -- they recently added an "Overheat Protection" feature that also completely disables the switch at temps ~freezing.

Based on excellent past performace of Zooz stuff out there, I have full confidnce this new switch will be fine too.

I had mine outside all winter in WI, worked fine all season turning holiday lights on and off. Got down to I think -10F (-30 with WC).

All zwave chips since 300 series were rated up to 85C (185F). I would have to dig more in the zwave specs to find this mythical 104F they specify, as that is definitely not a limit of the radios/mcu itself. Maybe it was back in the ZWave 100 days? Dunno.

Anyway, knowing that the components are rated higher means it is likely fine, and they are just too lazy to actually update/change their guidance. If they want to lose sales by specifying ultra conservative operating temperatures that is their business I guess.

EDIT: I will say that all the Aeotec sensors are only rated to 40C or 45C (104F or 113F) too. So who knows, maybe that is in the spec somewhere?

Sorry to derail this thread. I'll be quiet now. :slight_smile:

I was about to post that this switch isn't rated for motor loads but indeed it is. 1HP @120VAC or up to 3HP @ 240VAC. So that is good to know but interestingly this device will also work on 240VAC circuits, not just 120VAC. The ZEN71 and ZEN76 are only 120VAC. Nice option!

I wouldn't panic about the low temp spec in Texas. You have more to worry about with water lines freezing than a switch stopping working below 32 degrees. The indoor rating might be a limitation.

I’ve seen this before when I search their products- I think maybe it’s lowest price, like open box or something- even though there aren’t any at that price at the moment :man_shrugging:t2:

Yea, I don't get it. The ZG23 SoC they have used in at least some gear from Silicon labs is rated -40 °C to +125 °C.

Just posted links to two Zooz products in another topic and the same happened...significantly lower prices were shown in the post than actually on The Smartest House site. Likely designed to generate clicks...

I have some tube fluorescent fixtures in my basement that this would work great to control. I was going to risk using a ZEN76 and live with a short or sporadic operation, but it appears my procrastination has paid off yet again!

Victory. :wink:

Procrastination, it's not a weakness, it's a ...

I'll figure out an end for that saying later.
