Я использую плату K868-A16 но при подключении датчика температуры ds18b20 точность 0,5°С хотя датчик может мерить 0,1°С

Is there a version available for the KC868-ATC? Thanks!

no, KC868-ATC only have arduino firmware. Not use by KCS firmware.

hello!!!
i`m having a problem with this version ..
when using ethernet and i make a simple configuration in IFTTT like:

- WHEN DI1 IN BOTH EDGE ... THEN TOGGLE DO1

and in output menu I setup the DO1 to delay (20 seconds) then the ethernet blocks...
even the RJ45 connector leds turn OFF..

tested in A16 and AIO and both boards have the same problem

i tired to turn off and turn on the board... then it start well but a few time after the problem continues and the ethernet stops again

if I only remove the delay configuration to "hold on".. all restart working fine

next week we test it.

Hi (KC868-A6)

Seems like the sensor function has some problems at least when posting to mqtt

I have 2 sensors

• A DS18B20 that seems to have a lot of spurious readings
  
• A DHT22 that seems to sit on one value for a very long time, even if other sensors close by shows temperature variations way above the threshold
  

Other than that it seems like a great product!

1. About DHT22, whether update value in KCS monitor webpage?
2. do you integrate to home assistant by ESPHome yaml? or by MQTT?

The DHT22 does not update more frequently on the Monitor page than on mqtt. Looks to me as if the temperature over n time does not increase above thresold, then the new current temperature is used as reference.... ie if the temperature continue too increase slowly the valve is never update on webpage/mqtt.  If temperature change quickly it seems to work

The spurious readings on ds18b20 is hard to catch on monitor page soo not 100% sure if that also occurs on Monitor page.

Currently I have set the KC868 to connect to a mosuitto server directly (mqtt). Have no automations running here now, but have a simple node-red dashboard to visualise the readings from the mqtt server.

yes, you can test with mqtt broker, monitor the mqtt state topic. maybe you can record a video send to us by google driver or whatsapp number: +86-15381188302

Logfile

about 12 hours log, seems to be better than normal though. Still static readings for the DHT22 and some spurious on the DS18B20.
