Hi!
I've bought a new smart power socket from Action. Aparrently it's a new model that haven't been posted here. It is using CB2S module.

Hi, Thanks for the info. How did you open it without breaking the housing? Ok, found it: The hooks that hold it together are in the corners. So you have to press the edge on the side of a table at a 45°... [Read more]
In each corner on the back, there is a clip. I used a slim metal blade to force it a bit. [Read more]
Hello everyone, I also received the sockets today. Unfortunately, it is not possible for me to flash these with the Tuya Cloudcutter OTA. Which profile should you choose? The Tuya firmware is V1.1.17. Thanks... [Read more]
AFAIK, it is not in the profiles yet. I simply entered the settings listed in the JSON. In "BK7231 Easy UART Flasher," I used the button "change obk settings for flash write" and edited the details before... [Read more]
If you are referring to OBK profile, it seems to be here: https://obrazki.elektroda.pl/5843347000_1703230509_thumb.jpg Have you watched our tutorial videos? We have videos one per each device... [Read more]
Thanks for the information. It's a shame that it's currently not possible to flash these sockets OTA. Unfortunately, I don't have the time for soldering work at the moment. I tried to create a custom profile... [Read more]
Don't lose too much time trying. This firmware version 1.1.17 is using the SDK 2.3.3 that is patched. Cloud cutter will not work with it. [Read more]
It's easy to flash with wires, even if socket is hard to open. Here's how I handled one like that: https://obrazki.elektroda.pl/1882438300_1705054865_thumb.jpg https://obrazki.elektroda.pl/3917410300_1705054866_thumb.jpg... [Read more]
Thanks for the hint. I honestly didn't realize that. Fortunately, the LSC sockets are not glued and can be opened easily. Do you have a tutorial for flashing using a USB to TTL serial adapter?... [Read more]
We have many tutorials for that, here are two examples, N platform: T platform: [Read more]
Hello everyone, today I successfully flashed said sockets to openbk using a USB to TTL converter. The whole thing worked without soldering using jumper cables and test hooks. If you are interested,... [Read more]
Great Tip ! Just ordered those too ! Hinzugefügt nach 4 [Minuten]: Just managed yesterday to also flash one by myself. But I am personally using ltchiptool on debian cli myself to flash. Worked... [Read more]
The simplest way to get it automatically configured is to use our OBK Web App config extraction: Thanks to this, you can get GPIO config directly from Tuya partition. It's always better than guessing. Anyway,... [Read more]
Did it with a dump to get the pinout. Worked too. As said: only Voltage divider was wrong. [Read more]
I have just spontaneously registered here to add some more information. Maybe it will help some successors. Thanks also for the help I found here. "Action" in Germany still has some of these sockets... [Read more]
Hey! so i flashed the chip and all well. But when i calibrate the power, it stays on 2.5watt even the attached appliance is 100% off? Did i do something wrong or is the onboard powermeter not very reliable?... [Read more]
Apart from the 2.5W issue, which seems similiar to the problem I read in this topic: https://www.elektroda.com/rtvforum/topic4047633.html do everything else works correctly? Are 100W, 200W, etc, loads... [Read more]
thank you for the quick reply. Ill have a new go at calibrating (although i did it the same way as the athom) and read the given topic. once i know more ill report bank! [Read more]
