Can you try on the latest dev branch?

Changes will be available in the dev branch in a few hours from now and in the next release which is every 1st of the month.

Hi, Zigbee2MQTT Versione attuale: 2.6.0-1, install yesterday on my HA. i wait 01/09/2025 for new update ?

[Koenkk]

Yes (or switch to the dev branch (edge version))

[Simonz82]

how can I switch to the dev branch?

[Simonz82]

i have installed the edge version, now it sees in the list the SNZB-02P devices and sees that there is an update (as i said i have 0.0.00-2.1.00 and sees this: 0.0.00-2.2.00 ), when i click on update, it goes to error and does not update anything. there is however a bug i would say, the error is as follows:

z2m: Update of 'Temp Salone' failed (Device didn't respond to OTA request) Update of 'Temp Salone' failed (Device didn't respond to OTA request)

[Koenkk]

You probably need to wakeup the device right before clicking the update button.

[Simonz82]

Surely this is the case, but how can I forcibly wake him up, so that he immediately clicks update?

[Koenkk]

I'm not sure if the device has a button on it, but usually it wakes up when pressing that.

[Simonz82]

ok, perfect, thanks to zigbee2mqtt edge i have updated all the thermometers. in the OTA tab I also do not see the product SONOFF SNZB-05P, which however in the index I see listed, it is already updated to the latest version, but it is not listed for a possible check. Other products that it does not find and in this case are NOT in the index file are: TUYA: TS0505B_1 MIBOXER: FUT036Z SONOFF: BASICZBR3 is it possible to integrate them ?

Thank you

SNZB-05P

Enabled OTA for this now.

Changes will be available in the dev branch in a few hours from now and in the next release which is every 1st of the month.

For the other devices you would need to get the OTA either by requesting it from the manufacturer or for Tuya via this guide.

@Koenkk are you planning to merge in main branch? I can't see OTA for SNZB-02P SNZB-05P

Thanks

This device determined automatically here pressing the update firmware button does not help

What to do? Wake up?

[MattiaMarchiorato]

@a1ex-ak you have to start the paring mode on the device. Then you will be able to lunch the update.

[a1ex-ak]

paring mode on the device

What kind of mode is this and how do I start it?

[MattiaMarchiorato]

@a1ex-ak depends on the device, for snzb02p you have to press the button for 5 seconds.

[dkorunic]

I can confirm the above, SNZB-02P requires the following procedure:

• enable pairing process by holding button for 5 seconds
• red LED starts slowly flashing
• permit joining in ZB2MQTT
• immediately start OTA through ZB2MQTT

OTA itself takes around 30 minutes if the SNZB-02P is in reasonable proximity to ZB gateway.

[Simonz82]

how come i can't create the groups? example: I create the temperature group, then when I go to add the sensors inside, I get errors, so I can't actually fill the groups with the various devices.

[dankarization]

Where can I find information about changes in new firmware for snzb-02p

What about SNZB-04P OTA Update?
