We are running LogicMachine (LM1 + LM2 redundant setup) with multiple (we have 5) CANx DALI gateways (CAN-DALI-M3) in a hotel automation project. Since our on-site configuration session on March 20th, we have been experiencing intermittent issues with the CANx DALI GWs (Experienced 2 issues).

Environment
  • LogicMachine ×2 (for redundant)
  • CANx DALI Gateway (we believe ESP32-based)
  • Multiple rooms assigned per CANx DALI Gateway
  • Approximately 30 DALI drivers are assigned to a single DALI gateway
  • Use WAGO 787-2857 for DALI external 18V supply
  • Every 15 minutes, a querystatus command is sent as a batch via sendcmds to all DALI drivers assigned to each gateway

Code:
[KNX BUS]

KNX-red   ------------------+---- LM1 KNX+
                            |
                            +---- LM2 KNX+

KNX-black ------------------+---- LM1 KNX-
                            |
                            +---- LM2 KNX-


[CANx BUS]
CAN-white  / CAN L -------+---- LM1 CANL
                          +---- LM2 CANL
                          +---- DGW1 CANL
                          +---- DGW2 CANL
                          +---- DGW3 CANL
                          +---- DGW4 CANL
                          +---- DGW5 CANL

CAN-yellow / CAN H -------+---- LM1 CANN
                          +---- LM2 CANN
                          +---- DGW1 CANN
                          +---- DGW2 CANN
                          +---- DGW3 CANN
                          +---- DGW4 CANN
                          +---- DGW5 CANN

[DALI]
DGW1 DALI+ / DALI-  ----------------> DA-01
DGW2 DALI+ / DALI-  ----------------> DA-02
DGW3 DALI+ / DALI-  ----------------> DA-03
DGW4 DALI+ / DALI-  ----------------> DA-04
DGW5 DALI+ / DALI-  ----------------> DA-05


Symptoms
  1. The CANx DALI GW randomly enters a hung/frozen state. The green LED stays lit solid, but LogicMachine CANx's device scan cannot find the GW ("device not found").
  2. When the GW hangs, lighting scenes and dimming commands from LM scripts stop working entirely. The DALI lights remain on at their last state but cannot be controlled.
Suspected causes
  • Excessive signals on the DALI BUS causing the GW to hang
  • The ESP32 hanging under load
  • We have confirmed that event scripts on one of the two LMs that call arc or gotoscene are disabled, so duplicate commands from the dual-LM setup are not the cause.

Questions
  1. Is there a known issue with the CANx DALI GW freezing under heavy DALI BUS traffic?
  2. Is there a safe way to remotely reboot the GW without physically accessing the panel?
  3. Are there any watchdog or auto-recovery settings we can configure on the GW?
  4. Is there a recommended way to monitor the GW or CANx status (ping, heartbeat, etc.) so we can detect hangs automatically?

Any advice would be greatly appreciated. Thank you!]]>

I would like to confirm the following:
If the DALI bus of the CANX DALI Gateway is short-circuited, where does the circuit protection operate — on the PSU side or within the Gateway itself? I mean that in case of a short circuit, will the 18V PSU continue to operate normally, or will it be affected?

It would be ideal if the PSU could continue running even during a short circuit on the DALI bus.

Thank you in advance for your support.

Best regards]]>

The device assigns a separate short address for each channel (R, G, B, and W). In LM we have configured a group as RGBW to control it jointly. The group controls for on/off and intensity work correctly. However, the color control from the group has no effect. If I send the commands individually to each short address, the color change works correctly.
Could this be an error?

I'm in the process to create a parking supervision project to help aout collegues to understand if the internal company park is full

I would evaluate a self made solution using LM + CAN + LORA
here some specs:

Parking floors: -1 and -2
L x W (each floor): 80m x 80m (heigth 2,20mt)
Spot available for each floor: 156
Special characteristics:
on floor -1 I do have contitioning and heating pipes on the celing
on floor -2 there are firewall gates to isolate half of the space (the normally stay open)

I do not need lights on single spot, just a general light at floor entrance with a green or red light (but could be a future installation)

I can provide a LoRaWAN device to be placed on each spot, but I'm wondering if LM can handle such scenario and how.

thanks in advance

Is there a quick and easy way to replace faulty ballasts in DALI CANx?

Let me explain: sometimes it can happen that one or two ballasts fail and need to be replaced. I usually connect the new ballast and search for it, but the system forces me to configure it again. Is it possible to automatically detect that a new ballast is connected and assign it an existing address without affecting the rest of the connected ballasts and the parameterization?]]>

I create an association in DALI CANX and I can operate the lights... but in KNX is not working ? Why? 

The lights are only ON/OFF dali (without dimming)... that helps ?
