    I've added plug model name to the title. It's LSPA9 plug I think. They come in variety of types, I had ESP8266-based LSPA9, and CB2S-based and WB2S-based as well. They are sometimes glued well.

    I managed to open the plug, but how do I put it together again?
    I can glue it together, but then re-opening it may be cause a problem.
    Is there any recommendation on fixing this?

    Are you referring to LSPA9-style model, like shown in this topic?

    Well, as far as I know, there is no other method than a little glue... just a little drop of glue. Not more.

    Those devices are cheap and they capacitors may fail, so be prepared... fix is quick and easy, but do not glue it permanently.

    Also make sure to use PowerSave 1 in OBK.

    I have 2 of those. One has a BK7231N and the other a BL602. The latter was a bit tricky to flash because the description how to do it was not easily found, but I eventually got openbeken running on both of them.

Topic summary

LABEL_AI_GENERATED
Discussion about opening a Tuya LSPA9 WiFi smart plug without damaging the enclosure, noting that these plugs may be glued tightly and exist in several hardware variants. After opening, the main concern shifts to reassembly: the recommended approach is only a small drop of glue, not permanent bonding, so the plug can be reopened later for repairs. Alternative reclosure using thin transparent medical tape is also suggested. The thread also mentions different internal WiFi modules and firmware flashing, including ESP8266, CB2S, WB2S, BK7231N, and BL602, with OpenBeken used successfully on some units. PowerSave 1 in OBK is recommended, and the devices are noted as cheap and prone to capacitor failure.
