Blue Series Fan Switch Firmware Changelog | VZM35-SN

I updated to the latest 1.07 firmware for this switch, but now HA is showing another update but the version is just 0xffffffff. Any idea what’s going on?

I think this is an issue on the ZHA side. We definitely don’t have a firmware of version ffffffff in any repo or listed in any manifest. I would say that you might need to restart HA or maybe do an “image_notify” in the ota cluster for the device . . . of maybe hit “skip”. If you have 1.07 installed then hitting “Install” should either cause nothing to happen or HA will report an error as it tries to apply a firmware that doesn’t exist.

Any plans to update the Home Assistant Quirk to allow easy setting of single tap mode through the GUI? I know you can go through “manage device” and go through the drop downs, but it would be nice to have it on the main device page along side all the other options.

I haven’t planned on doing it because for the settings to show up in the main device page the source of the ZHA core code has to be modified . . . so I haven’t been wanting to add bulk to that repository. I think @chack has had the same opinion which is why we have kind of held off. Here is the repo in question:

zha/zha/zigbee/cluster_handlers/manufacturerspecific.py at dev · zigpy/zha

I think that is where you would add them at least.

It at least used to be a couple places to get it to show up on the HA device page, I’ll have to go look to see if that’s still the case or what’s changed with separating ZHA out of the HA codebase.

I don’t know that I can guarantee I can get something started this week, but I can try to add it within the near future.

I just noticed that these switches don’t report power or energy summations. Any word on how to fix this?

I am using ZHA in home assistant. I have 7 of these switches and none of them report energy sensors. The 11 light switches I have report energy without issue.

Going from memory, from a conversation I had with @EricM_Inovelli a couple weeks ago, the fan switch (and the module) don’t have power monitoring hardware on board.

That’s bizarre… this post would insinuate otherwise:

It was originally included in converter, but it was removed as the fan module doesn’t have the components required for power monitoring as @rohan said above.

Huh. Why wouldn’t the fan switches have power monitoring?

I’m not an electrical expert, but I’m pretty sure it has to do with the fact that the circuitry is designed to handle inductive loads which requires a different set of components to monitor the power. And I am guessing that they are not natively found on the chipset that was used.

That matches my understanding as well.

I am transferring my zigbee devices from hubitat to z2m. Turns out that at least one of my fan switches is on V1.06 and isn’t recognized when i pair it to z2m. Is there any fix for this in z2m, or do i need to bring my hubitat back out and use it to update the firmware? @EricM_Inovelli

Had to really think back about firmware 1.06 to remember what the deal was. We only left that up for a short time because it was discovered that the mfr info was missing in the fw. There used to be a trick with z2m that you could use to update the firmware, but I think it doesn’t work anymore since z2m changed how they handle ota about a month ago. You will probably have to add it back to Hubitat and do the update from there and then add it to z2m.

Adding the switch back into hubitat worked. Hubitat didn’t recognize it as an Inovelli switch when I added it, but I was still able to update the firmware and confirmed it was at 1.07. I was then able to bring it into z2m without a problem. Only odd thing is that the firmware in z2m shows as 1.06 even though I know it updated in hubitat and the switch works perfectly. It looks like my fan switches are a mix of 1.06 and 1.07 so I’m updating the rest of the 1.06 switches.

This is a little quirk about z2m. Sometimes it doesn’t query the fw of the switch for some reason and will display the older version. At the bottom of this article are a couple of things to get it to show the correct info:

Blue Series • How to Update Firmware With Home Assistant (Zigbee2MQTT) | Inovelli Help Center

Has anyone had trouble with their Blue Series Fan Switches losing network connectivity? I have a large-ish deployment of Blue Series dimmers (40-50) and 7 fan switches. I realized today that every one of the fan switches seems to have lost connectivity to my habitat. Local control still works fine. If I pull the air gap, it will again be reachable from the habitat for a while, but will drop off again after some time.

Hi @rdb, I have only heard of this on an older firmware for the fan switch. There is something with some Hubitat hubs that messes with the keep alive feature of Zigbee. I don’t remember all the details, but we released a firmware that disabled that functionality and haven’t heard of any issues since. Can you confirm the firmware version you are running on your fan switches?

Hi @EricM_Inovelli – yeah, I’ve got old FW (1.04 IIRC). Just after I posted my message I updated 2 of them and they’ve been fine since. That’s likely it. Thanks for confirming.

No worries, I think you should be good, but let me know if you need anything else!
