Last fall I installed two of the newer ZSE42 XS 800-series Water Leak Sensors in the basement of our home in New England to complement a single, original ZSE42 700-series Flood Sensor already in service for over a year. The newer devices use the CR2450 battery, whereas the older units use the common CR2032 battery found in so many devices.
Installation of the new sensors was done October 2nd and I replaced the CR2032 battery in the older sensor at the same time.
Today, April 5th, the two newer sensors with the CR2450 battery are still showing 100% battery, after being in service all winter while we were away from that home. The older sensor with the CR2032 battery stands at 17%. I’m impressed with the experience to date with the 800-series ZSE42–way to go, Zooz!
Now, if the ZSE41 Open/Close Sensor were updated to use the CR2450 battery, would it stand a chance of lasting the winter in an unheated garage? The ZSE41 sensor I installed there to replace an older, original Z-Wave door sensor about the same time last fall is down to 21% battery–now that outside temperatures have gotten above freezing, that is. (While the temperatures up there were below freezing, it consistently resulted in notifications from the Z-Box Hub about low battery.)
Although I haven’t researched the temperature coefficients of the CR2450, perhaps it is better in lower temperatures? At minimum, it “lasts longer” due to its increased capacity.
Once the Z-Box Hub implements LR functionality, it could possibly improve battery life on these cool, little sensor devices in our home, as LR adjusts transmit power to be gentler on batteries…
I got the open/close on my mailbox in Norway (frezzing cold)
Installed in september I think (ordered in august)
It reports low battery when it is -5 and below during winter to. But when it is above +5 again it reports higher values again.
And it is still working on the battery that it came with
But it is now at low battery life even when we got 10+ now
But also hope the LR soon will come to zooz hub and nice home senters some how(maybe with a slave with 700 chip)
Hey @Barkis and @Brors94 , great news for you both Beta firmware is now available for the Z-Box hub (5.172.18) with Z-Wave Long Range enabled! Please let us know if you have any feedback on the new firmware and LR implementation. We’ll be officially announcing it shortly, but the update is already available on your hub as a beta release.
After installing the beta firmware that enables LR support on the hub, do LR devices have to be excluded and re-included to benefit from LR?
Is there a way to tell if a device is in LR mode in the hub UI?
Update from my testing: I think the answer to both these is “Yes.” You have to pick LR vs regular when including the device, so exclude and re-include is needed. You can tell something is LR by it having a device id of 256 or greater.
@zoozer correct on both counts! If you include a device in the mesh, the hub establishes the necessary route of communication during the inclusion process. Since ZWLR is direct hub-to-device, you would need to exclude and re-include the device as a LR device. The node ID is also correct here as well.
@Brors94 not sure if it works with hc3l. Official support for the Z-Wave Long Range protocol in Europe is scheduled for April of 2025. However, devices that are currently available in Long Range in EU frequency will still need a complete SDK update due to a shift in the EU frequency specifically for Z-Wave Long Range.
We will be updating our EU devices to support the long range protocol in Europe, but it will take time due to the required SDK update for the frequency shift.
Updating current devices via OTA to support Z-Wave Long Range for EU is a possibility at this time, though we have not yet confirmed this detail.
This is excellent news, @Sara! I’m looking forward to trying this feature when we get back north! (We’ve been in Florida for the winter and I haven’t even loaded the latest release that came out for Z-Box, as it can’t be done remotely. Probably will load that release first, then follow up with the Z-Wave LR support a few days later.) Thank you for the update!
