SNZB-02D: add support for temperature and humidity calibration

[photomoose]

Adds support for local temperature and humidity calibration.

Requires firmware version 2.2.0 on the device!

Is there a way to programmatically hide these additional properties in Z2M if the firmware version does not match? Or does the release containing these changes get pinned to a release of zigbee-OTA containing the new firmware?

How do we find/get the v2.2.0 OTA file in zigbee-OTA? Or is that a task for a Sonoff developer to do?

@sonofftaotaoliu / @liubotongs any chance you could provide us with the OTA?

@sonofftaotaoliu / @liubotongs will be happy to get SNZB-02D v2.2.0 OTA as well.
Thanks a lot in advance!

OTA upgrade via Z2M for the SNZB-02D device would be appreciated very much. I was unsuccessful to upgrade using the eWeLink app. Like others, too, see this thread in the eWeLink forum.

I send an email to ITEAD/SONOFF support. Let's hope they will reply.

Thanks @stickpin.
→ ITEAD/SONOFF support: I will buy more of these devices, when I can calibrate the temperature and easily upgrade to the latest firmware.

Could you provide a way to update the firmware from 1.0.9 to 2.2.0 ?

If using Z2M, you'll have to wait until Sonoff provide us with the firmware. Once that has been done, the update will be visible in the OTA tab in Z2M and as a notification in HA.

Alternatively, if you have a Sonoff Bridge, you can temporarily pair the device with that and install the firmware update using the eWeLink app, as it is available there right now, then bring the device back into Z2M.

Thanks @photomoose. QQ: have they provided firmware upgrades for Z2M in the past? How likely is it they will respond?

Hello, my colleague is responsible for the SNZB-02D, but he is still on Spring Festival holiday. Please kindly wait.

Hi @sonofftaotaoliu,

Sorry to bother you, any update on the OTA firmware?

Thanks a lot in advance. :)

@photomoose might be you mix with this one: Koenkk/zigbee-OTA@63b4157 ?

I don't see any commit for SNZB-02D

Sorry, I'm getting confused between devices (reading these notifications on my phone). Yes, I was mistaken for the TRV, I've removed my previous comment.

Hi @sonofftaotaoliu, have you any news about the firmware upgrade? It would be great if buyers of the product could update it easily and make use of the calibration feature.

Thanks, Bernd
