Hi everyone！

if there is a ZC with a lot of ZED which were power by battery。

if ZC was broken someday, How could we keep those ZED to saving power at this time？

because if we do not have do something for ZED ，it will search network again and again until it shut down。

so what is a good way to solve this problem？

You can let ZED stop rejoining after it tries a couple of times to rejoin but fails.

This is implement in Z-Stack Home 1.2.2. You can refer to -DREJOIN_BACKOFF=900000 in f8wconfig.cfg which implement rejoin retry backoff silent period timer duration in milliseconds - default 15 minutes according to HA test spec.

ZED would try to rejoin every 15 minutes in Z-Stack Home example. In the end, it will join back when ZC is turn on.

Yes, ZED of Z-Stack Home 1.2.2 can work with ZC from Z-Stack Home 1.2.1.
