ewelink smart plug CK-BL702-SWP-01(7020) sending read genTime every 7 seconds

[ronnist]

What happened?

I find this ewelink smart plug is sending a genTime request every 7 seconds. With four of them in the network they are spamming my zigbee mesh.
For every read request
debug: z2m: Received Zigbee message from 'Smart plug', type 'read', cluster 'genTime', data '["localTime"]' from endpoint 1 with groupID 0 ,

my coordinator replied
debug: zh:controller:endpoint: ZCL command 0xb40ecfd0d12345678/1 genTime.readRsp({"localTime":816738678},

This process repeats every 7 seconds for each of them.

What did you expect to happen?

I wonder if I can stop the smart plug sending the time request.
I know it maybe down to firmware level but not sure if its due to a configuring problem.
Last resort, is there a way to stop z2m replying the genTime readresponse this will at least reduce 50% of the network transmission.

Thanks in advance!

Could you provide the debug log of this?

We cannot prevent the device from sending it but we can prevent z2m from replying, this is what I've implemented 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.
