ZigBee Fan Switch | Project Zephyr (Blue Series)

[tiger658]

Welcome back from your time off Eric! Hope it was restful!

I was trying to reverse engineer the ZHA quarks that are being used for the fans, and it seems like it is just copying all of the configuration from a VZM31SN rather than querying the device for the components it supports.

Is that intentional, or does the ZHA Quark need updating to support the new switch? I tried modifying a local copy of the quark, but I was struggling to confirm that it was actually changing anything.

Here is a link to a GitHub issue discussing the problem.

@EricM_Inovelli @Eric_Inovelli i have already tried to reach out to Hubitat and was told it an inovelli issue and i have to work inovelli.

Anyone else have opinions on how cumbersome it is to use this switch as a 3-speed fan switch?

You have to hold the switch to change the speed of the fan, and you never really know what speed it’s going to be. It would be easier if you could just hit the up button to cycle between the 3 speeds, and the down button to turn it off.

Yes, the user experience is less than stellar in my opinion. The “dimmer” like behavior is made worse by the general ambiguity of the led bar. So far every person that has tried the switch, has expected to be able to cycle speeds by pressing the paddle up, not holding it.

That can be coded into an automation, but that truly seems like a hack to implement something that should exist in firmware. An automation will never be as responsive and trouble free as being implemented in the switch itself.

Bump @EricM_Inovelli.

Could you confirm that there is no power monitoring and temperature monitoring?

[mamber]

I’m not EricM (both Erics are very busy these days )

But I am one of the beta testers and I wrote the Hubitat device driver. The VZM35 Blue Fan Switch does NOT have power monitoring, but it DOES have internal temperature monitoring.

@mamber

but it DOES have temperature monitoring

To clarify that’s the switch’s internal temp and not the room temp

[harjms]

@stu1811

not the room temp

Or outsides temperature.

[mamber]

thanks for the clarifiers. Yep, its an INTERNAL temp sensor, not room nor outside

Even if that is true, the LED’s are different. Take one apart and find out for yourself. At first I thought maybe the settings aren’t the same, but setting to blue on either ends up being different colors slightly.

Yes, we just confirmed this yesterday and are trying to figure out what the course of action is. Manufacturer’s aren’t just supposed to change the bill of materials without letting us know.

What they told us is that they swapped out the LED’s with better ones (at first I thought this was just them saying it, but upon testing, it’s actually a much better LED when comparing certain colors against each other) and also they are much more efficient from a heat perspective.

That said, they still need to tell us when they do things like this as it leads to issues like this.

The net of it is that the latest batch of Red 2-1’s, Blue 2-1’s and Fan switches all have the same LED’s in it – the original couple of batches of Blue 2-1’s have the different LED’s in them that don’t match the new batch.

What the manufacturer has offered to do is figure out if a firmware change can be accomplished or look for ways to tweak the settings (via intensity or color values) to get them as close as possible.

@johnconstantelo

At first we tried white, and wow is the white not the same white across the different batches.

Yeah, this is the most noticeable one. At first, when I was alerted to the color change, I saw the blue and went, “yeah, ok, that does look different, but I’m sure it can be solved via tweaking a few things”, but then I changed it to white and dang… I must say the new white looks awesome though.

@grooves12

It may a different diffuser on the switch. I can see individual LEDs through the diffuser on the Fan switch and I can’t on the Light switch.

Yeah, this was brought to my attention too and I confirmed with the manufacturer that they did not change the diffuser, but it is weird that at certain angles you can see the LED’s.

@Jaxel

Anyone else have opinions on how cumbersome it is to use this switch as a 3-speed fan switch?

@MasterDevwi

+1 on this. I’d prefer it if up increased the speed by 1 and down decreased the speed by one. Then again, that does make turning on and off the fan slower (or maybe you’d have to hold down the button?). It sounds like a “smart bulb mode” like setting should be available, so I figure I might use that and program the behavior I want in Home Assistant once button presses start registering.

@mamber

But I agree it would be a nice built-in feature (selectable via a user parameter/setting) @Eric_Inovelli @EricM_Inovelli what to you think about getting this added to the firmware (P16 perhaps?)

I agree with this enhancement, really good idea!

We hadn’t even considered this to be honest. All the fan controls I’ve ever played with have had the hold to change speeds, so it never crossed my mind to include something like this.

But, you guys definitely aren’t the only ones who’ve asked for this feature (unless you both are blowing up the ticket system under different aliases lol jk) and I think it would be a fairly simple firmware upgrade.

Let me see if we can add this to a future firmware release! I’ll put it in GitHub right now

Thanks for the suggestion!

@fisheromega

Button Numbers … I did not see what the button numbers are in the online manual. Did I miss them or are they not listed? I know button 1 is a single click, but what button number is the config button?

Button Mapping Tables • For Multi-Tap Scene Control Devices | Inovelli Help...

Good suggestion to put them in the manual. I’ve been revamping the Knowledge Base and trying to make it more user friendly, so I’ll add this to the scene control section or something.

@uLLfAEVeKVgMvpiA

Bump @EricM_Inovelli.

Could you confirm that there is no power monitoring and temperature monitoring?

Just confirming, although @mamber is correct – no power/temp monitoring in the switch – just an internal temperature monitor that is there to prevent overheating.

–

All, if I missed something, let me know – I’m just getting caught up!

[kwilliamm]

Will any future switches such as project Linus use the exact same LED?

[SamJWard]

I would presume that all switches going forward will use the newer LED’s.

Reason: The old LED’s are no longer available anywhere in China. Looks like they updated them and no longer produce the older ones.

The older ones = Blue = Cyan color temperature
The newer ones = Blue = Darker, true blue temperature

[tiger658]

@Eric_Inovelli and @EricM_Inovelli, what is the path forward to fix the Home Assistant ZHA issue?

In summary, Home Assistant (ZHA) is erroring trying to query the switch for “active power reports”, but as there is no power monitoring in this switch it is causing the rest of the device capability discovery to fail.

Is it as simple as updating the ZHA quirk, or will fixing the issue require a firmware upgrade?

[Eric_Inovelli]

I’m going to have to defer to @EricM_Inovelli on this one. Is anyone else facing this out of curiosity? Sorry, haven’t monitored the forums as well as I should’ve so I’m genuinely asking.

[chack]

I believe it’s going to end up being an HA update and not something that can be overridden by changing the quirk, but there’s an issue open with the ZHA github.

[tiger658]

Does HA check every device for active_power_report? The current quark copies all of the attribute list that is queried from the VZM31SN cluster and then removes a couple of attributes such as active_power_report. Is that the correct way of handling this device? I would have expected the quirk to query the VZM35SN directly for it’s capabilities.

Sorry, I don’t mean to drag this discussion too deep technically. Happy to move this discussion to a better forum to discuss this issue, I just want to know the right place to track the resolution to this.

Thanks!

[MasterDevwi]

Thanks for the update Eric! I appreciate all of the hard work and dedication as always.

Any suggestions for how to get button presses working in ZHA? Right now the switch isn’t firing any events for button presses.

@MasterDevwi

As with @Gazelle, I’m able to see events for the LED changing when I press up or down, but the button press events aren’t fired. The config button doesn’t fire any events at all (which is expected since it doesn’t modify the LEDs).

In this case I believe it’s checking both the 2-1 and fan switches since they both use the same Inovelli cluster ID and the HA code just references that ID. Re the copy/remove, that was done by me after talking to one of the main ZHA devs who recommended it be done that way. If you go to the device page and manage it through that UI, you’ll see all the options work there, just having the issue with the frontend piece.

[tiger658]

Got it… in that case, how do we expose the LED settings HA then? I assumed that the power error was causing the query to fail of the LED settings, but maybe I was down a rabbit trail. haha

Thanks all, I really appreciate all of the hard work!

[chack]

From the device Page > 3 dots to “Manage zigbee device” (this one is from a 2-1, but it’s the same step)

Change the cluster to the Inovelli_VZM35SN_Cluster and pick the parameter you want:

Use “Read Attribute” if you need to check how it should look, but change the value and hit “Write Attribute” and that’ll push it.

(Also enjoy the per-led settings that are available there for both the 2-1 and fan switches if you’re so inclined )

[tiger658]

Ya, I am tracking that I can change the settings directly via the cluster commands, but I was hoping to have the drag slider like we have on the VZM31-SN.
