Domotz Causing Issues in our A/V Installations

Hey guys, thanks in advance for any help. 

 

We have about 70 Domotz deployed across the country in our customers restaurants and we are starting to experience various problems in a few of them that may or may not be related to the Domotz. 

 

In one particular restaurant that we just finished, on the final day of the install, our entire system started to freak out. We use HDMI over IP technology so our systems contain a lot of network switches, control systems (Crestron, AMX, etc), networkable amplifiers, IP controlled power supplies, computers/servers, networked DIRECTV boxes, etc.

 

So, on this last day onsite, the entire control system started acting funny...not switching video, lags, TVs not turning on and off (we send CEC commands through the network switches using our control system), etc. On a hunch, I disconnected the Domotz box and everything started acting normal. It seems like Domotz was sending/receiving so much information that it just overloaded the network and caused all of our other equipment to not function properly. At least thats our current theory.

 

Now, we are experiencing similar issues in other locations and we are beginning to wonder if it's Domotz that is causing the issues. 

 

 

So, here are the questions we are trying to get answered:

  • Has anyone ever heard of a Domotz malfunction that causes high amounts of network traffic?
  • How can we check the status of the Domotz we removed that was causing the problem to see if it's functioning properly? 
  • Are there other things we should check for such as firmware versions? 
  • Any other thoughts at all as to why Domotz would cause something like this? 

 

Thanks again.

Hi Brian, 

 

Let me answer your questions:

 

  • Has anyone ever heard of a Domotz malfunction that causes high amounts of network traffic?

We do know that some devices doesn't handle the constant monitoring of the agent (we check every device on the network every 30 seconds with some ARP/ICMP pings, we we will also, depending of the device check some other protocols looking for available services and more sources of data like SNMP. The best for your particular case would be contacting our support so we can further investigate the problem. I also recommend you to check the switches logs to see resources consumptions and looking into the logs for errors.

  • How can we check the status of the Domotz we removed that was causing the problem to see if it's functioning properly? 

Again contact our support informing the Domotz Box MAC Address. Keep the unit connected to the internet (could be some other network). We will let you know if it is running our latest agent software and so.

  • Are there other things we should check for such as firmware versions? 

I would look close to the devices logs, searching for error messaged to better understand the problem.

  • Any other thoughts at all as to why Domotz would cause something like this? 

We know that some controllers doesn't act normal when inquired by the agent monitoring, we do have an option to blacklist devices and prevent them to be monitored by the agent: https://help.domotz.com/user-guide/automated-discovery-inventory/#Device-Blacklist 

 

Please get in touch with our support, we will do what we can to help you find the root cause: support@domotz.com.
