Yes... the newest sources hangs and resets the device after few tries when i randomly pick some color fast. I will try to debug on the another device, but maybe you will be faster.

I have lent my magic home to my kid's school for a light table :) I hope they will return it soon, until then I can only test it with other devices.

The same thing happens with H801.

Yes, I can confirm this too on all three of my MagicHome ESP8266EX controllers.

The web panel needs a reload after the device restarted to be able to pick a color again.

I have seen a hardware watchdog restart in Huacanxing H801 which uses the same PWM module as the MagicHome. It happens under stress but it's hard to reproduce.

Original comment by Griskevicius (Bitbucket: griskevicius, GitHub: griskevicius):

No no. For the H801 it is very easy to reproduce. It is a matter of time. Just change colors fast ant device hangs up. Or just dim. Sometimes it hangs up after a few seconds, sometimes after several. But it is guaranteed. If you leave it “On”, ir can stay up for 5 or 10 minutes, haven’t tested ir yet for more.

What I meant is that there is no clear action that will trigger the error. After some testing I found a stable configuration decreasing the PWM frequency to 1kHz and using TIMER1 in the PWM library. I have been testing it with the H801 for an hour without issues, stressing it from time to time. Could any of you test it on other devices like the Magix Home, using the dev branch code?

Original comment by Griskevicius (Bitbucket: griskevicius, GitHub: griskevicius):

I have just one H801. So I cannot help you with Magic Home controller. But I am looking to order more H801 controllers, so I could donate one or two of those if it would help you test. Also I am looking to test it more carefully next week. For a few hours ON and so on.

On Tuesday I will test the dev branch.

Currently after (commit) the device is not resetting, but it is barely changing colors or switching on/off (or sometimes not at all) :)

xoseperez · 2017-12-03T13:02:31Z

What does "barely changing colors" mean?

xoseperez · 2017-12-03T20:12:43Z

Original comment by gimi87 (Bitbucket: gimi87, GitHub: gimi87):

After few changes it stops changing. Depends on luck few tries later maybe the device will change the color.

Original comment by Kruno M (Bitbucket: Kruu51, GitHub: Unknown):

It happened to me also. I flashed 1.10.0 version. After one day it stopped responding from Domoticz (on/off) only. I tried trough web interface (fixed IP address) and it worked once. After that I cant connect, I dont see it in my router list.

So I restarted it (4 times power unplug and 2-3 sec waiting in between replugging - that way the original firmware is restarted so tryed it and it worked) but, when restarted I see espurna_xxxxx wifi, but password is not default but it is my password. OK I connect to it, but cant access 192.168.4.1 address., page not found. Ping that address and it is there but not able to load.

So I am waiting new espurna to try flashing it with Platformio again, becausa I cant use upgrade.

Hey,

i am back and testing on the MagicHome controller. ^^

 ets Jan  8 2013,rst cause:4, boot mode:(1,6)

wdt reset

... and the device restarts.

Dev Branch

On commit 489d629

OTA

At first I thought the ota firmware was broken, but it seems that the device needs one complete power shutdown (physically) to work correctly again. Then after some seconds it will work like intended.

Directly over USB

Again I could not reproduce the fast color switch bug. Also nothing was in the log visible that could indicate the bug.

Issue both

I experience after 4-5 seconds a short burst of color flickering whenI do a fresh boot (physically toggling power switch). Also some more seconds later there can be again a flickering. After the second flickering it does not appear again.

Summary

Wow, great work!

It works perfectly and that smooth color transition is sexy.
Also it seems that you accidentally resolved a buzzing noise problem I had with my controllers. :D

But to merge it into the master, that flickering may need some attention. It does not bother me, so I will keep running the dev branch on all three MagicHome controller.

Hi just upload espurna-1.10.0-huacanxing-h801.bin here is the video when the bug appears it looks unstable

Dev branch. It looks like there is an issue with the ESP8266_new_pwm library in some devices. Using TIMER1 makes it only work at 0% or 100% duty cycles on an Arilux LC01, on an H801 works great. Only have this two right now but using NMI at 500Hz frequency seems to be stable for both of them. Currently on dev. Will test it further before release.

I have opened an issue on the pwm library to find out what's going wrong. I think Stefan will know better if there are issues with different timers and other peripherials (StefanBruens/ESP8266_new_pwm#18).

@SirGioVan 1.10.0 is known to be unstable. If 1.10.1 works it will solve your issue.

Original comment by elmicha (Bitbucket: elmicha, GitHub: elmicha):

If I disable "Use JSON payload", it doesn't crash. If I enable "Use JSON payload" (even if MQTT is disabled), it crashes if I change the values too fast.

Here's a shell script that changes the values from 0 to 255 if you call it with -s:

#!shell

#! /bin/bash

key="apikey=C3424D34B2B10143"
api_url="http://espurna/api"

usage () {

  echo "Syntax:  
                 h801.sh -s|--stresstest
                 h801.sh R|G|B|W1|W2 number
"
  exit 1
}

h801_curl () {

  data="value=$2"
  method="PUT"
  case $1 in
    W1-colorwheel)
      url="$api_url/rgb"
      data="value=$2,$2,$2";;
    R)
      url="$api_url/channel/0";;
    G)
      url="$api_url/channel/1";;
    B)
      url="$api_url/channel/2";;
    W1)
      url="$api_url/channel/3";;
    W2)
      url="$api_url/channel/4";;
    get)
      url="${api_url}s?$key"
      method="GET"
      ;;
  esac
  curl -X "$method" -H "Accept: application/json" --data "$key" "$url" --data "$data"
}

case $1 in
  -h|--help)
    usage
    ;;
  -s|--stresstest)
    shift
    for i in {0..255} ; do
      h801_curl R $i
    done
    ;;
  *)
    h801_curl "$@"
    ;;
esac

LOL, certainly this use case was completely out of scope... anyway, this is happening because when "Use JSON payload" is enabled messages are being queued and the queue fills the available memory and makes the device crash. I'm adding a max size for the queue to avoid this. When the queue reaches the max size it sends an MQTT message with all the contents and empties the queue. The code it's already in the dev branch. Will be released with 1.10.1.

xoseperez · 2017-12-05T18:22:27Z

Changes released with 1.10.1.

Last sources are working great. No issues with color transitions or without on Magic Home 1.4.

xoseperez · 2017-12-08T16:21:06Z

Closing issue then :)
