Hello folks,

can confirm. The old version of the dimmer switch:

https://www.zigbee2mqtt.io/devices/324131092621.html

and new version (v2) fail.

https://www.zigbee2mqtt.io/devices/929002398602.html

All of my Philips dimmer switches (1x old) and (10 x new v2) refuse to OTA update.

@rmi1974 Did you wake up your v2 dimmers by pressing a button? With that, mine all updated. The v1 dimmers did not. I got one to update by making it perma-awake via reporting settings (1/5/0), but hat to re-interview afterwards to get the new FW recognized by Z2M.

mundschenk-at avatar Feb 07 '25 21:02 mundschenk-at

I also had problems in updating my old v1 dimmers, but finally 2 of them are updated now and one ist still in the process of updating. You need a lot of patience, always restart, do not more than 1 device update in parallel. Keep device alive. Press a button immediately before clicking the Ok button to start the update. It took me the entire day to get 2 out of 3 updated.

Newer dimmers and also the old indoor motions sensors as well as the newer outdoor motions sensors updated without problems.

jonofe avatar Feb 08 '25 07:02 jonofe

I beliebe the difference is that the v1 accessories are not ZigBee 3.0 conformant, whereas the newer ones are.

mundschenk-at avatar Feb 08 '25 08:02 mundschenk-at

I have 4 v1 and 1 v2 of the switches.

The v2 updated fine. 3 of the v1's appear to update but the following morning say they need update again, they will go thru the process of updating and appear to update but again will claim they need updated the following morning

1 of the v1's point blank refuses to update giving the log errors I posted earlier.

I never had issues updating these the last time there was updates for them.

chenks avatar Feb 08 '25 08:02 chenks

@mundschenk-at thanks for the hint. I forgot about the sleep mode on those devices.

After running around, pressing one of the buttons once/twice, the v2 devices were able to update from:

20210729 2.45.2_hF4400CA

to:

20241001 2.77.39

Related to this "deep sleep" mode, but off-topic:

This (deep) sleep mode on those philips dimmer switch devices is really annoying. I have various other multi-button zigbee remotes (tuya), that never show this behaviour, reacting instantly on button presses. Especially when people need to press buttons at least twice because the device needs a "wakeup" to have some action done because the first button press is "lost" (required to wakeup?) Annoying for guests who expect the switches to operate like normal physical switches. Can someone tell me if it's possible to disable the sleep mode on those dimmer switches. I'd rather have them draining the batteries faster than the "this switch doesn't work properly" experience.

Regards

I just found a solution for my last HUE dimmer v1. I updated the firmware of my Zigbee Coordinator (SLZB-06p10) to version 2.7.1.

Changelog of that version is:

Fixed Zigbee OTA updates for SLZB-06/p7/p10.

After that update I only had to try 2 times until the update of my old HUE dimmer was successfull. Even in the first try it got close to completion (>95%). Second time it finished successfully.

So in case you are using ths SLZB-06p## Coordinator with an older firmware you could give it a chance.

jonofe avatar Feb 08 '25 14:02 jonofe

I'm using a sonoff e controller and it's already on the most ember firmware

chenks avatar Feb 08 '25 14:02 chenks

Me three. Every HUE Accessory will result in fail in OTA. Either wont't start the OTA (timeout). Or the update will start, but after some period of a time will fail by Restarting the adapter. I have a solid 150 devices network, good connection, no interference, everything is rock solid - except the OTA of HUE Dimmer Switches (both Gen 1 and 2) and Motion sensors. I've tried it on EZSP 6.x.x as well as on Amber 7.4.4 versions of the SONOFF E coordinator. I've tried setting lower package size in OTA, pressing the buttons to wake accessories up, setting ping mode to accessories every 5 secs, nothing has worked for me.

I was able to update one of my Hue v1 dimmer switches, even at the first try, funnily the firmware version stayed the same after the update.

Still trying to update the other two, one of them got until 52%, but failed then, the third one didn't even start to update until now.

nephrotranz avatar Feb 09 '25 14:02 nephrotranz

It didn't update, it failed. Tomorrow morning it'll be back in the list to showing update available

chenks avatar Feb 09 '25 14:02 chenks

It didn't update, it failed. Tomorrow morning it'll be back in the list to showing update available

The update was already three days ago and it definitely went to 100%.

nephrotranz avatar Feb 09 '25 14:02 nephrotranz

If the firmware version didn't change then it didn't update

I've been thru this for 3 days running. Each switch claims to have update but the next morning they all appear again saying update available

chenks avatar Feb 09 '25 14:02 chenks

If the firmware version didn't change then it didn't update

I cannot tell you if you are right or wrong...

When I checked the dev console after your comment I saw that all clusters were gone, so I thought the switch could be broken.

I then connected it to the Hue Bridge, but surprisingly the Hue Bridge was showing that the software version of the switch is 67.115.5, which is the most recent one. I then switched back to Zigbee2MQTT again and there the SW version and date shown is still the old one ( 6.1.1.28573).

Clusters etc. are back now and the switch is fully working.

No idea what is happening, but as long as it is working and the update notice is gone it's ok for me.

nephrotranz avatar Feb 09 '25 15:02 nephrotranz

New update, it now fully stopped working in Zigbee2MQTT although I can connect it. But when connected there is simply no light flashing when I press any of the buttons.

So I really do not know what happened.

I will connect it to the Hue Bridge again now and will not try to update the other switches.

nephrotranz avatar Feb 09 '25 15:02 nephrotranz

To confirm my status, I only have issues with v1 hue switches.

My v2 switches, hue bulbs and hue motion sensor all updated fine.

It's just my 4 v1 switches that won't update - 3 appear to update and complete but the following morning they appear for update again and 1 refuses to even start to try and update

I made the same experience and I tried it 3 times.

3 times the dimmer v1 was updated up to 100%, but the version did not change.

Finally I found out, if you trigger an new interview after "successfull" (100%) update , the new firmware version is recognized and the dimmer shows the updated FW version in the z2m portal.

what do you mean by that? you mean you have to sit and watch the live log until you see successfull" (100%) update, and then interview it again? that is going to be quite time consuming if you have to multiple switches.

clearly doing that can't be considered "normal".

chenks avatar Feb 10 '25 09:02 chenks

what do you mean by that?

simply do an re-interview after the update has finished without errors. If the update breaks with errors, this obviously does not help.

all 4 of my v1 switches aren't showing an update fail, but a re-interview does nothing.

okay, then it's not a general solution. For my last v1 dimmer at least it worked out.

Adding my voice to the cacophony:

I have 5 V1 switches, I wake one of them up by pressing buttons before and after I tell Z2M to update and the firmware upgrade seems to work, but then the next day updates are available again. Obviously one device at a time is safest...

I've tried using the "Interview" button in the Z2M web UI to re-interview the devices, alongside the same method of "waking up the device" by pressing buttons for a few seconds before and after... This doesn't seem to be doing anything. Is there a different way we should be waking up/preparing these V1 dimmers for re-interview? Perhaps the old paperclip in the back, or holding On/Off for 10 seconds?

Otherwise I'm stuck in the same boat as a few others here, firmware update appears to work but either the firmware doesn't actually apply or I'm not getting the correct firmware version from the switches. It's hard to tell, either way Z2M doesn't seem to believe anything is amiss.

i tried your suggestion, it didn't work. i triggered an update on the switch, watched the log to see it complete to 100%. re-interviewed the switch by pressing the blue "i" button within zigbee2mqtt devices screen. it said it completed. waited 24 hours and the device re-appeared in the list of devices requiring an update.

I had the same issue with the Philips Hue dimmer switch V2. For me it helped to trigger the update in Z2M and then click twice the off button on the dimmer. Then after few seconds the update progress started - first with time N/A and then later with ~ 30 minutes. It worked for my 4 dimmer switches the same way. I did not have to re-add them.

this issue is related to v1 switches, not v2. v2 switches have no issues updating.

And yes - the update keeps going to 100% and failing without any warning / error / issue.

So my final status is the following now:

Hue Dimmer Switch v1 No. 1: Successfully updated with Z2M after 2 tries Z2M is still showing the old firmware version and date, but when I connect it to the Hue bridge the Hue app shows the new firmware version Re-connection to Z2m does not change it, BUT when I search for new firmware via OTA, it says there is no update available

Hue Dimmer Switch v1 No. 2: I had no chance updating it with Z2M, failed 4 or 5 times After connecting it to the Hue bridge two days ago the old firmware version was shown in the Hue App, I had to wait until tonight, but in the end the switch was updated to the new firmware version via the Hue bridge. BUT now comes the big surprise - I re-connected it to Z2M, but here it still showing the old firmware date and version although it was updated. Searching for updates also brings the result that no new firmware is available

So the conclusion is the update for v1 is possible with Z2M, but it can be a pain in the a** The frontend does wrongly show the old firmware version and firmware date, but when searching for an update it is recodnized that the switches are updated to the newest version.

@nephrotranz: Yeah, if Z2M says there are no updates available, you can just reinterview to show the correct version.
