Random Reboot Sonoff T1/T2 when MQTT + Hue Bridge enabled

[ymurawski]

Hi, i have faced out a problem when MQTT (iobroker with Sonoff adapter) and Hue Bridge Emulation in Tasmota is enabled.

I have many random reboots of my devices.(Sonoff T1/T2/T3 and Sonoff Basic)

When i deactivate Hue Bridge Emulation everything works perfectly with IoBroker.

In attachment you see some pictures.
"Decken Licht HWR" is using Hue Emulation and "Decken Licht Kinderzimmer" is not using Hue Emulation
There you can see the runtime of both devices.

What i tried so far is:
-complete flash delete
-new Firmware 6.4.1.4 with Core 2.5 and 2.4.2 and 6.4.1 with core 2.3
-sleep 1
-sleep 0
-sleep 50
-new install of iobroker on different computer

See attachment for Error Logs and screenshots

Hi,

Can you please complete the troubleshooting template?

When you have the reboot? At anytime or doing something in particular?

Have you tried core 2.3.0?

Can you self-compile? If so, try to disable mdns discovery

[ymurawski]

Hi,
i already tried with core 2.3, same problem.
the reboots are in random time. even when i dont do anything.
I didnt to self compile before.

[ascillato2]

Ok, Can you please complete the troubleshooting template?

[ascillato2]

Are you using the hue bridge emulation for Alexa?

[ymurawski]

Yes im using this for alexa because i dont want to use cloud.

Could you tell me what the troubleshooting template is ? Sorry i dont do that often :)

[Jason2866]

Dont use special characters in SSID: wifi @ home is a very bad choice!!!

[ymurawski]

Dont use special characters in SSID

But does this cause the problem ? When Hue Bridge is off the i have no dissconnects.

[ascillato]

Alexa uses the cloud a lot ;)

The troubleshooting template is there when you open a new issue. You have either opened a blank issue or you have deleted the text.

[ascillato]

Please, try to change your wifi ssid as Jason suggested. No special characters neither spaces

You asked for help, so it is your choice...

The issue is IoBroker related
#4721

[ymurawski]

So i opened a new WIFI called "WIFI Home IoT" but still the same.

Yes this was my Post but it has been closed and not reactivated

[Jason2866]

Yes, because it is NOT a problem from Tasmota

[ymurawski]

Yes, because it is NOT a problem from Tasmota

Ok thanks for the information. What can i do next ? :(

[Jason2866]

Contact Iobroker people for help.

[ymurawski]

Ok i will try. I will post here if there is a solution

[ascillato2]

There is something definetely wrong in your firmware ("LoadAvg":999) It is using full cpu (?) It is processing a lot of requests from your network?

[ymurawski]

Mhhh I dont know. Maybe tasmoadmin that refresh every 5sec my devices?!

The only access on my devices are tasmoadmin and iobroker Vis

[ascillato]

I also use TasmoAdmin with the 5sec default besides MQTT and KNX and my devices are with "LoadAvg":19

So, there is something in your network. To achieve that usage, Tasmota is receiving a lot of requests. May be from mDNS.

Try the following: in the Tamota console type weblog 4 to display more debug information and there you can see if there is something wrong with mDNS or other types of requests.

[ymurawski]

I think my hue Adapter does many requests.
I added a hue Adapter in iobroker because the sonoff Adapter doesnt work.

[ascillato]

Ok, great. You have found the issue.

The adapter in iobroker is not working well and it is spamming your network.

If the sonoff adapter is not working and you are facing a lot of issues with iobroker, may be it is better to change to another Home Automation Software. There is a list of softwares with links and tutorials for Tasmota in the Tasmota wiki

[ymurawski]

I will try to deactivate the hue Adapter and let it run for some hours to See if I can use hue Emulation for alexa and sonoff Adapter in iobroker simultaniously.

[ymurawski]

OK in Info 3 there is an error. Do you know what this mean? It keeps restarting.

[ascillato2]

That is out of memory. Not enough RAM.

[ascillato2]

The epc1:0x4023e42e is refering to an internal function of the core 2.5.0

(In the http://thehackbox.org/tasmota there is also a MAP file that is a text file with those numbers EPC and the functions related)

[ymurawski]

Is that a serious problem?
You mean not enough RAM on my Sonoff device?!

[ascillato2]

which brand of router do you have?

[ascillato2]

Seems that your Sonoff is using all the available RAM due to the large amount of requests.

[ascillato2]

Please, try the reduced Tasmota version: http://thehackbox.org/tasmota/020500/sonoff-basic.bin

[ymurawski]

I use netgear Router because I need a 10gb/s Sfp Port for my network server

The Most common error that comes when the sonoff is restarting is RestartReason":"Software Watchdog"

[ascillato]

Please, try the reduced Tasmota version: http://thehackbox.org/tasmota/020500/sonoff-basic.bin

That one doesn't have mDNS discovery and some sensors

[ymurawski]

So far it stayes online. Lets See if this works. I will let it run for some hours and then Check it again

[ascillato]

If it works, the issue is some device spamming in your network with mDNS requests.

[ymurawski]

For now its running 20min without an error.
With sonoff.bin it restartet around after 5min.

But LoadAvg":999 is still the same.

Maybe the hue Emulation uses that much?

[ascillato]

The hue emulation is very light. It should remain below 50.

The good thing is that now your device is not rebooting. You should check your network traffic for multicast protocols

[ascillato2]

Closing this issue as it is not a Tasmota issue.

Issue: too many multicast requests to Tasmota making the core 2.5.0 to crash
Workaround: using Sonoff-Basic.bin version that does not have mDNS discovery

Anyway, please, keep us posted if you find the device that is making lots of multicast requests. That would be very useful for other users having the same trouble.

Also you can try to turn off multicast in your router or changing the multicast IGMP version in your router config to V3.

[ymurawski]

Hi, i found the Problem with my AVGLoad 999

It was just the command sleep 1

with sleep 50 it dropped instantly to avgload 19-20
