Suddenly communication between gw & nodes stopped , rebooting pi sometimes solves it

[Richard van der Plas]

@gohan what i see is that the mysensors.json isnt updated with values of the different sensors on the node ?
log shows:

child_id 3 already exists in children of node 11, cannot add child
3:26 PM /srv/homeassistant/lib/python3.5/site-packages/mysensors/__init__.py (WARNING)
child_id 2 already exists in children of node 11, cannot add child
3:26 PM /srv/homeassistant/lib/python3.5/site-packages/mysensors/__init__.py (WARNING)
child_id 1 already exists in children of node 11, cannot add child

Node 11 is unknown
3:25 PM /srv/homeassistant/lib/python3.5/site-packages/mysensors/__init__.py (WARNING)

Small update, using the 2.1 library issues are not there so much

[gohan]

I moved it to the home assistant section. Let's hope somebody could help you out, I'm not HA expert

Don't know if that is caused by the controller, by I'm having the same issue months ago but with domoticz.
When that happens, I've found that manually restarting the mys GW service makes it work again.

The same issue here and solved by changing my NRF24L01

I have the same problem

[gohan]

what version are you using?

[A Former User]

@gohan
My last node (8-relay) 2.2.0
my gateway RPi3 git clone https://github.com/mysensors/MySensors.git --branch master
I think I have some other nodes on 2.0.0

[A Former User]

sometimes I see this in my gateway log

Mar 13 17:42:32 MySensorsGW mysgw: !TSF:MSG:SEND,0-0-2-2,s=255,c=3,t=8,pt=1,l=1,sg=0,ft=0,st=NACK:0

[gohan]

@gieljnssns said in Suddenly communication between gw & nodes stopped , rebooting pi sometimes solves it:

mysgw: !TSF:MSG:SEND,0-0-2-2,s=255,c=3,t=8,pt=1,l=1,sg=0,ft=0,st=NACK:0

that looks like the message got lost between the gw and node. You could try moving the node closer or using a repeater halfway. Pls write the gw version since the git-clone is not telling me much

[A Former User]

@gohan
how can I see wich version I'm using?

[gohan]

when GW starts it prints the version in log

[A Former User]

@gohan

There is only 4 meter in between my gateway and node.

@huỳnh-minh-khải said in Suddenly communication between gw & nodes stopped , rebooting pi sometimes solves it:

The same issue here and solved by changing my NRF24L01

I've already changed my radio

[gohan]

Do you have a decent capacitor on the radio module? Have you tried a different maker of nrf24 module?

[A Former User]

@gohan
I have these radios https://www.ebay.com/itm/400594940658?rmvSB=true

I've used this adapter plate for my radio https://www.ebay.com/itm/200960749614?rmvSB=true

And there is a capacitor on my radio

[gohan]

I don't like those nrf24 modules as they are 99% fake clones. Once I got some real ones I solved a lot of range issues

[A Former User]

@gohan
Can you give me a link to the real ones?

[gohan]

I bought them on aliexpress from the cdebyte shop. There are a few open topics about real and fake nrf24 if you want to read some more. As a general rule of thumb consider that the genuine nrf24 chip is normally sold around 1.2$ so you can't buy a fully assembled genuine module for less than a dollar.
