Zigbee not making connection with EM24 and CCGX

Hello, i have a problem to establish Zigbee Connection from EM24 to CCGX.


The documentation of zigbee is horrible...

is there something known about the LED Behaviour of the zigbees?


my rs485 zigbee status:

Active LED: blinking rapidly
TX/RX LED: NO ACTIVITY


my USB zigbee status:

Active LED : on
TX/RX LED: blinking (maybe 1hz)


maybe somebody has an idea whats going wrong?
Or Maybe additional informations about LED Behavior or Button Functionality of zigbee?


best regards

Michael

Dear Michael,

I have exactly the same issue with 2 pairs of ZigBees.

Two weeks before I purchased 1 pair and because I couldn't establish a connection, i ordered a second pair last week. Same problem:

RS485 Zigbee status (DRF2659C):

Active LED: blinking rapidly

TX/RX LED: NO ACTIVITY


USB Zigbee status (DRF2618A):

Active LED : on
TX/RX LED: blinking


I also have a 3rd pair, probably 1 year old. This is working without problems (DRF2619C, DRF2618A).


The 2 newer pairs (DRF2659C, DRF2618A) are marked with "Zigbee2nd" but on the old one it is just "Zigbee"

Thanks for reporting as well @IronTom16, I will pass along your report as well.

Hello Thomas,


thanks for your information. So im glad that im not alone with this :)

think there might be an issue with batch of the zigbee usb transmiter.


i opened a rma with my supplier now and keep you up to date here.


best regards

Hi

I've tried 3 zigbee-usb with zigbee-rs485 and and one work straight out of the box.

I now have 2 zigbee-usb pairs that don't work!

symptom is the zigbee-usb first plugged into ccgx and just the power led lights no tx/rx flashing as the victron manual says it should!

The RS485 just has the active LED flashing.

Question which one of the pair is the master and should therefore initiate the pairing?

what do the buttons do?

Can you hard reset to a factory default that should work?

The documentation on this product is inadequate, I had one unit blow up, and needed to pair a replacement, so how exactly do you do a reset on the paired device, trial and error and two weeks wasted time, thats how

Hi @Michael Schmidt, @IronTom16

We've found out the (possible) cause of connecting issues, and updated the manuals on this:


note on old and new zigbee converters

Please note that there is a new zigbee converter available now, that is -not- backwards compatible with the old converters.

If you have a non compatible set, please ask your supplier for a correct version.

'old' type:

ASS300400100 - Zigbee to RS485 converter partnumber: DRF2619C

ASS300400100 - Zigbee to USB converter partnumber: DRF2618A

'new' type:

ASS300420100 - Zigbee to RS485 converter partnumber: DRF2659C

ASS300420200 - Zigbee to USB converter partnumber: DRF2658C

Hello Daniel,

thanks a lot this lights the problem up.


I will contact my supplier to receive correct set.


After this i will post the result here.


best regards

Michael

After receiving a set of Zigbee "2nd" (maybe Generation) it was possible to connect them.

Was not easy out of the Box they was not pairing automatic. Needed to pres Function tripple or twice and long reset togeter. then pairing startet and was finished after maybe 10 sec.

STILL not Documented what the exact way is :)

To add to what Guy already wrote: we're looking into this, and will update when we know more.

Hi @Michael Schmidt,

Is this the documentation procedure steps that you followed when first connecting the unit?

Hi Guy,

glad to hear from you that soon. Customer will be here at lunch and yesterday i received the zigbee. so im in little trouble now :)

yes i did the procedure as in the Manual.


but Led behavior of RS485 Zigbee as above.

Active LED: blinking rapidly
TX/RX LED: NO ACTIVITY


is there is possibility for total reset to repeat the procedure?

should the TX/RX led from rs485 zigbee blinking?

For a complete restart, I think some software required, I haven't done it before, so also looking into it now.

The manual for the Zigbee product from it's manufacturer is here - 10201-drf-zigbee-module-v52e.pdf

@Michael Schmidt

I have the units on my bench here and I cannot recreate your LED code combination of Blinking ACTIVE LED.

On the RS485 units; With only the DC power supply connected (and measured with a multimeter between 5-28V), disconnect the RS485 communications socket.

Press and hold the reset button.

Doing this on my unit (with the USB side disconnected) I get a solid Active LED and a 3 HZ TX/RX LED on the RS485 unit for ~60 seconds.

Still with the RS485 comms cable to the energy meter disconnected, if I connect the USB converter to the Cerbo GX.

I get the same Solid Active, and 3 hz TX/RX on both for 30 seconds.

Then Solid Active and 1 hz TX/RX on the RS485 converter.

If I then connect the RS485 to Energy meter comms cable.

The both the USB side and the RS485 side begins much more frequent blinking (intermittent 5-8 hz) and the Energy meter shows up on the Cerbo GX.

Hello Guy,

checked now with second pair of zigbee USB and Zigbee RS485.


Doing this on my unit (with the USB side disconnected) I get a solid Active LED and a 3 HZ TX/RX LED on the RS485 unit for ~60 seconds.

I tryed the same (USB zigbee is disconnected) and RS 485 only powerd by 12V.

RESULT:

RS485 to Zigbe device its only
-blinking Active LED (approx 3hz)
-no TX/RX activity on LED (not on and not blinking)


Guy can you maybe try this with Zigbee devices of actual shipped batch?
i had this exactly same behavior on 2 different divices now!


best regards

Michael


Thanks for reporting back.

I can’t reproduce here, and will be waiting some time for a new replacement unit to check.

So will try to escalate this and see if we can get to the bottom of it (and improve the documentation at the same time).

Hello Guy,

do you already have some news for me?


best regards

Michael

I asked internally at Victron.

No one else has seen your issue, these things all worked out of the box when following the instructions, up and running in 10 minutes.

I was told to suggest you RMA with your supplier to see if they can reproduce the issue, and then go from there.

ok but dont think this is necessary because none zigebee devices are around here.


do you maybe have documentation about led behavior?

this might be very helpful for debugging.
