modify index.json snzb-01m_v1.0.5.ota add telinkEncrypted

I’m not sure whether this change is correct. When I previously submitted the SNZB-01M OTA image, I had included telinkEncrypted, but it seems it was removed later.

However, when I tested OTA in my own Zigbee2MQTT environment using a lower-version SNZB-01M device image, I saw the same error in the logs as mentioned earlier about failing to parse Telink-encrypted OTA.

So I added the following field in my Zigbee2MQTT configuration.yaml and used a local my_index.json to test OTA.

In my_index.json, I used the same configuration as in this repository, but added telinkEncrypted.:

After restarting Zigbee2MQTT, OTA worked normally.

This started because some users reported that SNZB-01M could not complete OTA normally in Zigbee2MQTT, so I ran the tests and steps above.

When you have time, could you please take a look and let me know whether this is the right way to handle it, or if there is a better approach?Thank you!

Hi. What is your Z2M version?
(I think telinkEncrypted is not needed on the latest version)

[Oniums]

zigbee2mqtt-2.6.3

[andrei-lazarov]

Well, please update Z2M and check again.
Latest is 2.8.0, very soon 2.9.0.

I tried again later with Z2M version 2.8.0 and attempted to OTA the SNZB-01M directly, it still failed.But this time the failure reason seems different.

fetch failed

Normally you get this error when there is no internet access.

Can you access these links from the same computer where Z2M is running?
