The Zwave module will not work unless the antennas are connected The zwave module has a range of about 25 feet taking into consideration walls, etc. Zwave is an RF mesh network and requires either a range extender or other modules to relay the zwave signal beyond the range of the zwave controller module.

The antennas, are required and are included with the module. they're about 3 inches long and come wirh an elbow which allows them to install in a vertical position.

There are two external antennas, one for zwave and one for zigbee. They attach to those coax connectoers.

The scene data resides in the devices of the scene, as well as the controller and PLM You could turn off the controller, unplug the plm and the scene will still work, assuming there's no powerline issues. i.e. if you disconnect the controlller and plm and then manually turn on one of the switches in the scene, the rest of the devices in the scene will respond accordingly.

The scene test is very reliable. It appears that your problem is/was caused by noise on the powerline. How old is your PLM, the date code is the 4 digets on the plm sticker. Based on what you've described, It doesn't appear to be a PLM problem. If the PLM was failing it would effect more than just your scenes. A UPS or other electronic devices can wreak havoc with the Insteon powerline signals. A good start is the Fillterlinc.

@watson524 If you move up to the eisy the best PLM to use would be the 2413U. It's an USB model that plugs into the USB port on the eisy using a standard USB cable. The 2413U is currently backordered and will be available sometime in October. In the meantime make sure you always have a current ISY backup. There is no way to test your spare PLM without actually installing it on your ISY. For now it's probably best just to keep it as a spare. What's the current firmware version of your ISY?

@matapan Either you have a communication issue between the devices and your PLM, i.e. noise on the powerline, or the link tables in your devices are corrupted. First thing to try is right clicking on each of those devices and then click on restore device. That will rewrite the link tables that are stored in your controller to the devices. After the device restore run the scene test again to see if the issue has been corrected. Post the results

If and when it ever becomes available you'll find it on Insteon.com

You can start wirh scene diagnostics, right click on the scene then click on Diagnostics | Scene test Post a screenshot of the results

If the sensor is already linked, then yes, you can't add it again unless you first uninstall it. Being that you did a factory reset on the sensor you now need to right click on the sensor in your device tree and then click on restore device.

As @paulbates mentioned, your PLM has most likely reached its end of life. You should replace it with the 2413U PLM which is a usb model and doesn't require the adapter cable so there's less to go wrong. Be sure to follow the replace PLM procedure, see attached. Replace PLM Procedure (EISY or POLISY).pdf

The "version" in your admin console is blank and it shouldn't be What controller are you using and what is its firmware version Try clearing your java cache, be sure to check all 3 boxes, then download the IoX Launcher from here: https://isy.universal-devices.com/start.jnlp Also try removing power from the controller for about 30 seconds

The Zwave/Matter module supports up to the 700 series. It's supposed to support LR but I'm not sure if it has been implemented.

The zmatter module is supposed to support Zwave LR. However, when installing a zwave LR device I was never givren the option to use either LR or Mesh, so I believe they installed as mesh. Zwave LR by-passes the zwave mesh network and communicates directly with the Zwave controller and has a longer range than a non LR device Here's an article explaining LR All About Z-Wave Long Range - The Smartest House

Any zwave device that's zwave certified should work with the eisy. I have numerous Zooz devices and they are all compatible with the eisy. The ZSE50 is zwave certified.

@tracknut The eisy doesn't support a static address, only reserved addresses. Make sure DHCP is enabled on your router The PLM would be a non issue, so don't focus on it.

What controller are you using, and what's its firmware version?

@zorax2 After you get everything working and cleaned up do an eisy backup. Anytime you update firmware, devices, or programs always do a backup, it only takes a few seconds. You should also update to the current firmware which has bug fixes and program improvements

If the 2334 Switch added then your PLM and its connection is good. How old was the backup that you used to do your restore backup with? Was that backup made with your current PLM? If you backup is current then you can try doing a factory reset on the PLM, then a Restore PLM

In your browser enter https://eisy.local:8443/WEB/sysconfig.txt In your config settings, what are your versions for FreeBSD,UDX, and ISY

For the new 2477S you want to use "remove existing links. If you have the 6 digit device address, then in the linking window enter its address. The switch will then show up in your device tree with its address Right click on the old switch, then click on "replace with" and select the new switch. All your old switch data will be transferred to the new switch

What's the voltage and current rating on the failed power supplies?

The "failed to add device, reason 3" I believe that error 3 is "Device returned invalid node" Being that you have the correct device address 36.B9.BF, you should try removing power from the eisy then try installing again, but first do a factory reset again on the sensor. When the sensor is in the linking mode (slow flashing led) is the led bright? Also take a look at your device tree to make sure the device wasn't previously installed.

"Cannot determine Insteon Engine" usually indicates one of two issues, either the device is out of range of the PLM or you're inputting an incorrect device address when linking
