2GIG GC3 Panel Randomly Rebooting and Z-Wave Latency

My 2GIG GC3 panel has been acting a bit strange the last few days. The ADC commands for Z-Wave are taking 10 to 15 minutes to respond. I’ve also noticed that my panel has rebooted a few times today. I keep hearing it say “System Disarmed - Not ready to arm”.

Can you look in the logs and let me know if you see any issues? I have re-discovered the network a few times. I also put the system in test last night and send a remote reboot command from the system manager.

Thanks

I’m not seeing anything in history which would suggest a specific issue. I’m not seeing any evidence of remote commands being delayed by panel signaling, so it would appear a delay would probably be caused locally.

Can you point to a couple events where the delay occurred? The time-stamp would really help. We can look into those more in depth

Hi there. Good evening. I’m having the same issue as the OP says but my panel is a 2GIG GC2. I have recently updated the firmware. Everything worked fine for a day or two and then randomly rebooting, zwave latency or not working at all. Did re-discover, send reboot command, rebooted by battery/power unplug. Is there something you can check if issues been reported on system? Or any suggestions as to what I can do here to resolve, like maybe reinstalling FW 1.19.1.3? Downgrade firmware if possible? Thanks and please!

Hi there. Would reinstalling the same firmware 1.19.3.1 help out the issues of rebooting CP and major latency of Zwave ?

If your panel is already at 1.19.3.1, you won’t be able to flash to the same firmware version. Additionally, downgrading firmware via OTA is not possible. This is possible locally, but not recommended as a step in troubleshooting. Downgrading firmware will remove all devices paired to the panel.

Signal strength is reporting at a 2/6 which is adequate for communication but is relatively low. To troubleshoot, power down the system completely, transformer first (from the wall) then then internal battery. Leave the panel powered down for a full 2 minutes. During this time, check to make sure both antenna are plugged into the module and that neither antenna is touching metal/power lines when inside the wall (if wall mounted). Additionally, check to make sure the panel’s power cable is seated into the internal terminal block snuggly and has not come loose. After checking all of that, power up the panel battery first then transformer. Wait a few minutes after booting up the panel and check signal strength, any change?

I have sent commands to resync your Z-Wave devices, please allow 5-10 minutes for these commands to take effect. Afterwards, any change?

Additionally, I am seeing a Shed Door Z-Wave Lock reporting a malfunction. You will want to clear this from the network, then re-add it when able. This guide here will show you how. Be sure to pair the lock within 6 feet of the panel and to run a Z-Wave Network Rediscovery when done.

Thank you Tyler. Appreciate your help. I’ve gone ahead and power cycled as you suggested. Also, I’ve notice the zwave network as “unknown state please try again”. I’m waiting to see if everything is back to normal. I’ve check the antennas connections to make nothing shorting out or grounding. Also, made sure the power cables are fully secured. Signal (cell) prior to restarting was at 8/31 but after restart it is now 9/31, not sure if you were referring to this.

Yes that is what I was referring to regarding signaling

Did this show up shortly after rebooting? Sometimes it can take several minutes after reboot before being able to locally access the Z-Wave network.

Hey Tyler. Thanks! Ok, so the zwave is still going crazy and panel still randomly announcing “system ready to arm” or something to the effect. I’ve deleted the shed door and unable to reinstall, sometimes it shows up, sometimes I can even delete, so I have to try multiple time, wait sit and retry and finally able to delete shed door lock. Installed it again and still going missing even when left it next to CP. the zwave commands are taking forever and honestly, if I have to start from fresh, don’t mind. Maybe best option would be a completely wiped clean and start from scratch maybe? Even thinking of switch to the GC3. Any suggestions? And restarting system. Zwave state is unknown again

When you updated the firwmare, did you do this via the 2GIG USB Update Cable? If so, which firmware version were you on when you started and did you update right to 1.19.3.1?

This typically happens when the panel is rebooting, which usually only occurs when programming mode is entered, then exited, or when a firmware update happens (which are manual).

How old are the batteries in the Lock? They may need to be replaced.

This next thing to try, before fully Factory Resetting the panel, would be to reset the Z-Wave Controller and start from scratch there.

From the panel navigate to Services -> Z-Wave -> Wrench Icon -> Advanced Toolbox -> Rest Controller.

This will remove all Z-Wave devices and reset the Z-Wave controller.

Afterwards, you will still need to clear, then pair, each Z-Wave device.

Thanks Tyler. Yes, I did via USB cable and I was on versiona 1.19 and went straight to 1.19.3.1. I’ll try that. Because yep, still restarting. Zwave is going into unknown status. Just today, at 547p system rebooted and then 10 mins later, my office door sensor chimed, and the door was wide open no one had opened it or closed it. Through the night it continue “system disarmed” last one at 1117pm. The shed door lock I did swap batteries out and still same behavior, hate to think the door lock is bad since it was working fine before updating, but then of course I could always go bad too.

Were there any issues? Did the cable get moved or come out during the process at all?

While its possible that the lock is bad as well, its more likely that the problem lies with the panel. at this point.

After resetting the Z-Wave controller. I would only add a few Z-Wave devices, just to determine that they will in fact pair and work via the panel and remotely from Alarm.com.

If they don’t, then the last step would be a full factory reset (which will remove all sensors and devices)

Hi Tyler. One last time and sorry. Just before wiping the system out and starting from scratch (as you probably seen, I have a lot of sensors and zwave connected), the past week I have notice the CP reboots constantly and everything works for a while, and then zwave goes into “unknown state” and eventually it reboots again. It does that throughout the day multiple times sometimes take longer sometimes reboots in minutes. Any ideas? Possible big or firmware corruption?
Also, if I reset the system can we have a back up of the sensors please.
Thanks again
