Only Error light blinking: ISY cannot communicate with the SD Card. Please ensure: The micro SD Card (on the front) is seated properly. Unplug ISY, remove the rubber cap, using a sharp object, push the micro SD Card in so that it pops out. Push it back in so it clicks in. Apply power to ISY If reseating the micro SD Card does not work, you probably have a defective SD Card. Please consult Replacing/Formatting SD Card

Are you able to turn the switch on and off from the admin console? If you manually turn the switch on and off does its status correctly display in the admin console? Can you post a screen shot of the switch nodes as they appear in the device list.

If you use UD Mobile on your LAN you don't need a paid subscription. If you want to access your ISY remotely then you'll need a paid subscription.

@Hunter Aviator Be sure to do a Zwave backup(s) as you add the devices back.

You can try excluding them, then including into the Polisy Are they 300, 500 or 700 series zwave devices?

@andrewherman Try doing a factory reset on the KPL, then a restore device.

Battery operated devices go to sleep in order to preserve battery life. Did you wake them up by pressing the button on the device before you ran the interview process? You need to start with the Zwave device closest to the Polisy and work out from there.

It appears that your ISY link tables got corrupted, so when you restored your PLM the corrupted links got written to the new PLM. The only way that I'm aware to resolve this is to delete and reinstall your devices. Needless to say, be sure to do a backup any time you make changes to your devices or programs.,

@Don The 2450 is on back order. You can add your name to a notify list: I/O Module - Low Voltage Controller – Insteon Here's a Z-wave possibility ZOOZ ZEN17 UNIVERSAL RELAY – ZOOZ (getzooz.com) What did you end up doing that finally got your issues resolved?

Here's the link for 5.3.4 ISY 994i Series including Z-Wave support After the upgrade you must clear your java cache including checking the box "all installed applications" and then down load the IoX Launcher from here: start.jnlp

@sun-sense 5.3.4 (ISY994) - Last release for ISY994 - Current Release Announcements - Universal Devices Forum (universal-devices.com) Scroll down and you'll see the firmware link.

@sun-sense When you click on help about, what are your firmware and UI versions. Does the admin Console launcher on your desktop show as IoX Launcher?

Try removing power from both the PLM and the EISY. Power up the PLM, wait about 10 seconds then power up the EISY. Do you now see your modules?

@John Vickers Is this happening to just one device or multiple devices? Right click on the device, click on DIAGNOSTICS, SHOW DEVICE LINKS TABLE. After the device links fully populates, click on COMPARE. Does the compare show any mismatched links other the last one which should be all 0. Being that you have a new PLM I'm wondering if Insteon made any changes in their PLM firmware that's causing a compatibility issue.

Your PLM link count sounds low, about how many Insteon devices do you have? You might want to try updating your firmware to 5.3.4, which has some bug fixes.

Try removing power from both the PLM and the ISY. Wait about 15 seconds then power up the PLM. Wait another 15 seconds then power up the ISY. You can also try clicking on TOOLS, DIAGNOSTICS, SHOW PLM LINKS TABLE. What is the link count? What is your ISY and UI firmware versions? Is the PLM new or used. What is the date code and version on the PLM? Is the green led on the PLM a solid green?

Try doing a factory reset on the switch, then a restore device. to factory reset, pull out the set button then push it in and continue holding it in, the switch will beep. Once the beeping stops let go of the set button, the load will turn on, then do a restore device. Let me know if that fixed it.

Right click on a device that's not working, then click on restore device. Did that correct the problem?

@shm It's possible your PLM is failing. What's the 4 digit date code and version number? The good news is that Insteon now has PLMs in stock, so you might want to order a backup replacement.

Unplug you PLM, wait about 10 seconds, then plug it back in. Is the green led on the PLM lit? In the admin console, click on TOOLS, DIAGNOSTICS, PLM STATUS, does it show the PLM as connected?

@DRousseau Currently, does one of the switches turn on the load, or do both switches not turn on the load? If one switch turns the load on but the other doesn't then you need to create a scene with both switches as controllers in the scene.

Remove power from the EISY, then power it up, wait a minute, then press the front button ONCE. Wait about 10 minutes while the eisy updates. Clear your Java cache, including installed applications and then download the IoX Launcher from here: https://isy.universal-devices.com/start.jnlp Are you using the same PLM for both the ISY994 and the EISY? What is the firmware version on your ISY994?

The red wire coming from the switch provides power to the load. What do the switches control and how the load getting its power?

Try removing power from the eisy for a few minutes. Clear your java cache including all installed applications, then download the IoX Launcher from here: https://isy.universal-devices.com/start.jnlp After it powers up, press the front button ONCE, then wait about 10 minutes before you try to access the eisy.

It looks like you have your Rx and Tx connections reversed. Also make sure that Insteon is enabled in your configuration screen. Let me know if that resolves your issue
