Battery drain after change of router

[Jani_Uu]

I have set up Smartthings hub and sensors 3 years ago. Quite recently (4 days ago) I updated my 4G router and it seems like all my sensors started to drain batteries in only few days right after. I didn’t have time to update router firmware yet, and just wondering could that cause the sudden drain in all sensors?

Basically same behaviour for all of them…

Are these sensors Z-Wave or Zigbee? If you’re talking WiFi, it could be there is a conflict between your 2.4GHz WiFi channel and Zigbee channel.

The above screenshots are from Smartthings waterleak sensor and motion sensor so I assume Zigbee?

I installed my router (ZyXEL LTE5398) in a bit of a rush, so all settings are on ‘default’.

Which setting should be setup for 2.4Ghz channel? I assume it’s ‘automatic’ but not really sure.

This may be of help, Google may be of further help for channel information:

You can change Zigbee channel.

I’m using Zigbee channel 25 and WiFi channels 1-6 for my router.

Zigbee channels

Hi, I was wondering, would it be possible to edit which zigbee channels the hub uses? I read online that it may be possible for Wifi 2.4 GHz and Zigbee to co-exist if zigbee is limited to channels 24-26 and WiFi only to channels 1 and 6. I am using an Aeotec hub. Thanks in advance!

There are a lot of Zigbee issue currently reported in different posts on the forums over the past week. There is also an issue with Zigbee battery drain after the September hub firmware update discussed in the topic below. You adding a new router and Zigbee channel interference could be compounding the issue.

Zigbee Extreme Battery Drain

Hey guys… I have a Samsung Multisensor that is Zigbee and it has been experiencing wild battery drains in the last month or two. I’m talking 1-2 days and it’s dead. I’ve tried multiple name brands. I also have a similar issue on a Zigbee motion sensor, but it uses AAA batts so has a bit more staying power then the CR2450s on the multisensor. I’m tech savvy and have tried the usual things, including adding a Zigbee repeater nearby. Any ideas? These devices did not experience this issue before. The multisensor has been in use for 3 years without issue.

Actually, while setting up the router I did notice that my “Automatic updates” was off, and I took the latest firmware upgrade in… I will setup the channels and update here the outcome!
