@jkandasa Maybe I misunderstood the meaning of this class, but what about "message" instead of "field"?

@skywatch source and value looks very good to me!

@skywatch you could probably exchange messages thru MQTT queues, but being you I'd really invest my energies understanding how to use 2 gateways, since this is the standard way and you'll probably get more support for the community.
By the way, I have 4 gateways in my home (due to connectivity issue caused by concrete walls) and I never had issues with that in MyController.

@skywatch why do you need 2 instances?
If they are on the same ethernet netword, can't you configure one of them to use 2 gateways?

Hi,
could someone help me understanding what this error means and how to get rid of it?
Every day my log is full of messages like this:

IO error: javax.net.ssl.SSLException: Connection has been shutdown: javax.net.ssl.SSLHandshakeException: Received fatal alert: certificate_unknown in processing a request from /192.168.1.12:8443 / sun.security.ssl.SSLSocketImpl

I read other posts telling is was related to some script under "HTML additional headers", but that section is completely empty in my case.
It's probably something simple about https certificates, but I don't have any experience on this kind of things...

Thanks
Daniele

If others will arrive here searching for a similar issue: in my case the final solution has been changing the Arduino Uno I was using as ethernet gateway.

I'd like to be able to enable / disable a rule from my dashboard.
I could probably create a mock variable and then with a script change the status of the rule based on the variable value.
I was just wondering if there's a more elegant way to achieve the same result.
Thanks
Daniele

@jkandasa sorry to re-open an hold discussion.
the same error appeared again, and this time the gateway hard reset did not solve it.
do you have any idea on how to better isolate the issue?
thanks
Daniele

@Avamander could you please post me an example of DHCP renewal?
I investigated the ICMP ping idea but I've not been able to get something working, since the ping seems to interfere with GW code. Did you manage to use it in a mysensors GW?

I can confirm, chinese nano bootloader does not support watchdog.
All my nanos have MySBootloader (for this reason and to be able to use OTA update), but I don't want to use it on GWs since it takes 10-15 seconds to start because it searches for a GW in order to chech new OTA updates.
What I tried is to enable watchdog on a Uno (which in my experiments seems to support watchdog), but till now I haven't found a good way to check ethernet connectivity without interfering with GW functioning.
Do you have any idea on that?
Thanks
Daniele

@skywatch said in Frequent errors related to Ethernet Gateways:

d tried a 'new SD' card, did you flash tha

fresh install

@skywatch done multiple times during my tests, but nothing changed!

@jkandasa said in Frequent errors related to Ethernet Gateways:

our MySensors gateway ethernet device attached with Arduino

That's the same thing I thought, but having 4 of them all failing sounds a bit odd....
That's why I started looking also on the RPI side.
I tried also moving the ethernet cables from the swtich to the main router, to understand if the switch is having some issue, but still getting the same issues.

@jkandasa I've not been clear: could you please explain what's the difference between "Broken pipe" and "Connection reset" errors?

I yet tried with the old firmware, but I get the same errors, so the issue is somewhere else. =(

I made many tests in these days.

On the arduino side:

• downgrading mysensors library
• reducing and than disabling the RF24 message buffer feature
• Soft SPI
• adding capacitors to get a more stable power

On the RPI side:

• moved the ethernet connection from a switch to the main router
• moved from ethernet to wifi (to understand if there could be any issue on the RPI ethernet port)
• upgrading to mycontroller 1.5
• new SD card

I still see ethernet related errors, but now the message is slightly different, it talks about connection reset instead of broken pipe:

2020-04-14 10:04:42,138 ERROR [mc-th-pool-4] [org.mycontroller.standalone.gateway.ethernet.EthernetDriver:107] Exception,

@jkandasa could you please give me more details about the meaning of the 2 error messages?

Thanks
Daniele

@jkandasa I restart MyController Raspberry regularly (scheduled once per week), I tried doing that manually but nothing changed.
No changes on the router, but you made me remember I recently re-uploaded the sketches of my gateways and in this way I upgraded their mysensors library version.
I'll try downgrade one of them and see if this helps.

@jkandasa it's probably related to some gateway issue, probably connected to the issue I asked here

I made a hard restart of the gateway and now the error disappeared.
Thank you!

In the last week I often receive errors like this:

2020-04-03 09:03:30,572 ERROR [mc-th-pool-7] [org.mycontroller.standalone.gateway.ethernet.EthernetDriver:107] Exception,

I have 4 ethernet gateways, 3 based on Arduino Uno + W5100 Shield and 1 with Arduino Nano + W5500.
They never gave me a problem for more than 1 year, and now they're all suddenly showing connection problems.
I tried changing the ethernet cables and moving them to a different ethernet port: same errors.
They're connected to the same swtich I use for my laptop and I don't see issues, so I don't expect to be the switch.

Any idea?
Thanks
Daniele

This morning I was checking the resource logs , and I noticed some odd behaviour I cannot explain:

The same temperature is transmitted twice at the same timestamp, but my sketch reads the temperature once per second and sends it only when the absolute difference from the previous value is greater than 0.1°C.
This setup is in place from more than 1 year, and I never saw this beahaviour...
Any idea?
