Hi,

Would also be interested in new M30 board.

But looking for some details:

- What type of CT clamps are needed?  The M16v2 works with SCT013 with 3.5 mm jack, but what type is needed here ?

- Can you post details about the accuracy and especially if it can do stable readings of low power usage values like only a couple of watts. I would like to measure the real power usage of some electronic devices.

- Does M30 measure active power, so taking into account the power factor / cos phi ?

Regards,

Can install diferent firmware an use same time?

I have H32B which I bought few years ago. I was using it only by "shorting" contacts and everything works, but now I need to add it to HA. I that case I need to update firmware to enable MQTT (I am thinking so). Connecting directly by IP does not work, I hope it will work after update.

Connecting via NET REMOTE IAP works, I connect in 5 seconds after rebooting, ping is successfully returned, but when I choose firmware nothing happens. I have tried different versions of firmware but I am stuck on same result. As I do not know what processor I have, I have tried versions <5.x and >4.4

   

I have a problem. I have KC868-H32B Pro, KC868-AK ESP32 Programmable Keyboard, KC868-HA V2. How to connect them together? In Home Assistant, KC868-H32B Pro works with MQTT normally, but I can't connect KC868-HA V2 additionally.

i have the KC868-A16 REV:1.6 new and try to connect ethernet port and no open or no can see the lights, and connect to Router or my laptop, none show the ethernet port connect.
download the firmware "KC868-A16_Web_Server_Eth.ino.nodemcu-32s-202209151019.bin" install whit a ESP32 Download Tool, reboot and not see any change its the same

I would like to control groups of outputs quickly. E.g. set output1, output2, output3,... output15 to on, rest to off.
I'm mainly interested in wired ethernet connection (I expect it to give better results than WiFi).

I've expected the string format of TCP client/ TCP server would be best because the commands are quite compact. However, those protocols are not stable for me and are causing frequent disconnections.
Are there some protocol constraints like, wait until reply was received or something like that? How does the board recognize the end of the command anyways (there are no specifications about command delimiters, so packet fragmentation can cause issues here)?

Then I've tried MQTT but setting e.g. the mentioned 15 outputs takes non-trivial time (I would estimate ~500ms?). 
The MQTT command I've used is this one 

I have purchased the A8S v2. I have the USB cable and the device seems to be connected to port 3. I have connected the ethernet cable to that port on the device. I have downloaded the Flash_download_tool_3.9.2 and believe that I have updated the firmware with the KCS_KC868_A8S_v2.1.0.bin file. I now am trying to use the "SCAN DEVICE LIST" to find the device. I cannot update the static IP yet when I click the StartMonitorPort it says "The selected-ip maybe an invalid one, pls set the static ip first!" How can I do this?

How can I perform a full factory reset on this device? I have set a password but lost it :-(

I just purchased a new KC868-H32B but there is no QR code on the product itself?
What to do now?

what to KC868

Hi, does anybody know, how to use RS485 or serial connection with Tasmota firmware. There are no menus to configure parameters within KC868-A6 tasmota. bin
