Is there any possibility of RS485 connection ?

Hello everyone!

I have same problem like this posting https://www.kincony.com/forum/showthread.php?tid=1178

Did you solve this problem?

Problems I am facing.

1. KC868-H32B is setup with magnetic contactor and RC snubber. but sometimes it goes down. MQTT No response.

2. When it was not working. The setup page like this.


subnet mask and gateway changed.
3. When connecting included WIFI antenna. KC868-H32b goes down.

I look forward to your feedback..

Hi. Is the Alexa module still needed in the h32bs or is it already built-in there?

KinCony ESP32 application course is published on the udemy online course platform for everyone to learn for free. At the same time, we will publish on the online course platform of Espressif's official website, and we will continue to produce more courses based on ESP32 applications.

can this controller be updated from version 4.13.26 

allow for MQTT option?  4.13.26  4.13.26 4.13.26

Hi. I'm planning to connect the protection fuses before the relays, and not after as shown in the tutorials. This way I would be able to have one fuse for a group of channels (for example all lights in an area/room).

I do so because of 2 reasons: (1) Such connection is viable in my house because, for example, the wiring to all the lights for the living room is being passed through a single connections-box. Using wiring of different protected circuits in the same box is prohibited by law in my country. (2) Grouping circuits use fewer fuses and save space in the power distribution box.

Can such a connection cause any problem? The relays module has a varistor per channel, and I read online that a fuse has to be connected over the circuit with the varistor. My question regards the location of the fuse. Schematically, I'm asking whether it is critical to have the fuse on the closed-circuit between the varistor and the device (like you suggest in your tutorials), or is it also fine to connect the fuse to the feeding phase (leaving the closed circuit between the varistor and the consumption end device without any protection, as shown in the diagram below). I don't really understand the theory behind the varistor's operation, so I don't know if it may be a problem leaving it with the device in a closed circuit without protection on it.
   

Thanks for the help!
