Have a Zen76, Firmware 3.4 that has an update to 3.7 available in Home Assistant. Every time I try to update, it fails. Logs show: [3913783291664] Error during service call to update.install: zwave\_error: Z-Wave error 260 - Cannot check for firmware updates for node 32: Failed to query firmware version from the node! (ZW0260) Looking for any help, Thanks ---

So I have very limited experience with Home Assistant, but I’ll bet you get more replys shortly. However reading this makes me wonder if it’s something similar to what I experienced with one of my ZEN71s. [I mentioned in this post in the wishlist thread.](https://www.zoozcommunity.com/t/z-box-wishlist/535/27) Basically there are parameters the devices can lose that can prevent the updates (among other things that will stop devices from updating). In my case I was able to easily restore the missing parameters, then update without issue. ---

Thanks for the info, looked at all the parameters that HA offers and don’t see any of those listed. ---

Have you tried the basics of moving the Z-Wave hub closer? Rebooting the device (turning the breaker off and on)? Trying a different firmware file? Or removing and re-adding the device to your network? ---

Hub is 10’ away / will try the breaker idea / HA only gives me one choice for an update / Last resort, will remove & re-add. Thanks for the ideas ---

> [@JFBruns](#): > > Z-Wave error 260 - Cannot check for firmware updates Hello. This sounds like there is a connectivity issue or interview issue. Assuming the ZEN76 actually works and is controllable via HA; I’d start with a power cycle of the ZEN76 ( breaker off/on) which was already suggested. If that doesn’t work, perhaps a reinterview of the device. Then check the logs to be sure the interview completes properly. Then retry the upgrade. Let us know how you make out! We could also try a manual update of the firmware if needed. But I don’t think this is an issue with the firmware update itself - it seems to be failing the initial check where it cannot retrieve the current firmware version on the switch. If you can, an exclude of the device and then re-include might be in order as well. ---

I’m on Hubitat but I can confirm I have updated several ZEN76 devices to 3.7 firmware. So it must be something particular to your environment or how HA does the updates. If you have a ZWave stick you could run Simplicity Studio on a laptop and do the OTA firmware update from there. ---

Fantastic. Glad you got it sorted out!
