Was it Amazon or an Amazon Store? Amazon probably will have the latest but it depends on if any where still in stock for awhile. I have seen both 2.3 and 2.4 reported. Amazon Stores may have anything. Depending on how many they sold and when they last purchased from Smarthome.

I saw the same thing when I wanted to get a new 2413S from Amazon. I few days later they again had some. Stocked, Sold and Shipped By Amazon. It is almost like from time to time. They push the Amazon merchants stores products. Unfortunately they may not have the present, latest hardware version being shipped.

I believe my V2.3 has the same date code. Maybe around the same time you got yours. Maybe I have a surprise lurking in my future. Unless something has changed. You could do a cross ship. Where they charge you CC for the new replacement and then issue a credit when the old one was received back. Last time I did a Open/Closed sensor. They emailed me a FedEx prepaid return label.

You did make sure you powered up the PLM so it could initialize, before powering up the ISY994i? So it could be found by the ISY994i when it started. It does sound like the PLM may have failed. Your dates indicate it is within the two year warranty. You should be able to do a warranty exchange for a replacement. We have seen reports of recently purchased or warranty exchanges. Now being hardware 2.4

If it was on the same AC Circuit as the computing equipment, UPS or AC conditioning outlet strip and the equipment was not on a FilterLinc. Probably absorbing the power line signals. Forcing most messages to try and use the Insteon RF signals. Since the I/OLinc is power line only communications. It needed power line commands from either the PLM or another Dual Band device passing on the messages.

Yes it is a limitation in 4.6.2. Adding it as the earlier model Allows it to do basic functions. Some here that also have a HUB. Have used the HUB to set the options and then add it to the ISY994i Module Tree.

Glad you got it working.

The receiver may have a nice AC rated capacitor across the power line input. To keep its internal electronic noise from feeding back on the power lines. The cap will also absorb Insteon power line signals as noise. Even when Off. The capacitor is still there. That is why it is recommended to unplug devices when testing. As pointed out. Added another device on the same circuit, May have killed the signal even more. A FilterLinc on the receiver is one way to go.

Powering down the old PLM and ISY994i Powering up the new PLM letting it initialize. Power on the ISY994i so it detects the new PLM ID. Restore Modem (PLM) should go out and change all the old PLM ID number to the new PLM ID number. In the modules. I have seen some say. Restoring on modules may also be needed for some of them. I am not too good with decoding Insteon messages. I know an I2CS module will NAK back with an FF in command 2. If the senders Insteon ID is not in the modules Link Database. That maybe why trying to read the modules Link Database is failing as the new PLM ID is not in the modules Link Database.

Yes if the PLM ID is still the old one in the device. You would get a NAK from a I2CS enabled module. Response back from the problem module. Mon 01/29/2018 01:35:17 PM : [iNST-SRX ] 02 50 1E.02.E7 1E.47.4F AB 11 FF LTONRR (FF) So it is responding to the command.

The IOLinc is a power line communications only Insteon module. It most likely is not bad. You probably have a signal issue between the PLM AC circuit and the IOLinc AC circuit. While the Switchlinc to the IOLinc and PLM have a better power line signal. Could also be the SwitchLinc to the PLM are using the RF signals the IOLinc can't use. Do you have any Dual Band Modules or Range Extenders coupling the two incoming power lines and used the built in communications tests to verify good communications? Is the PLM on the same circuit as the computing equipment? They frequently absorb Insteon power line signals if not on a FilterLinc. You may want to unplug electronic devices and see if things change. As some also can absorb signals or make power line noise.

You may want to do a Tools Device Link Table test on the module. Then a compare to see if it is what the ISY994i thinks should be in it. The Restore Modem (PLM) should have written the new PLM's ID into the modules.

OK. Though the SwitchLincs we where talking about where the old 2476S/D power line only ones and in 2007 if my memory is correct.

I had some earlier hardware ones with the opposite issue. Local Buttons did not work but the control communications where fine. Smarthome had an issue with the small tact switches the buttons activated. They extended the warranty on that run of hardware to seven years.

Can't say about the outlets. I do know some of the modules also protect the relay contacts. With a resistor/capacitor snubber. When off there is a small current through the snubber. Can keep small loads like Christmas lights glowing when off.

Thanks for the information. I would not think they would have V2.3 units still in the warehouse but I got my V2.3 when it was the current model from Amazon 04/21/17.

If you purchased from Amazon. There are more than one source of the 2413S PLM. If sold and shipped by Amazon it should be the latest. If you got it from one of the Amazon Store Merchants. Then it is possible their stock is not as recent and you got an older hardware 2413S.

Was the 2466 being used at the time? Not highly likely but some devices are sensitive to Insteon power line signals.

In my tests. Since the Green LED is on the sensor Input circuit. It can glow Green and still be not pulled down close enough to ground to trigger the sensor. Sounds like the water sensor may not pull it close enough to ground. I would also try the parallel resistor mentioned. The only thing is the Green LED may glow dimly even when the water sensor is not on.

It does sound more like a display issue. Not 100% dead.

I don't have one. You may want to with the power off temporarily. Open the unit and then close it again. On the chance the pins on the boards headers where dirty. Where they connect to socket connected to the terminals on the back of the case. Maybe verify the terminals are tight holding the wires to the heating system.

My 2.3 looks the same as your 2.4. C7 and C13 mounted against the main board. With long leads bent at 90 degrees. Mine had a small glob of component glue holding them to the main board. On the Serial Daughter Board. You should find the 2.4 has a TI MAX232EI RS232 chip on it. It meets a stricter ESD specification. Over the chip in the earlier revisions.

I believe there was a 2.4 mentioned in a thread here. My 2.3 was installed on 04/21/2017 and is the revision Smarthome indicated a fix was implemented.

The original capacitor in the line powered side of the supply was a 6.8uF/250 Volt. The 10uF/400 Volt was chosen as the replacement. Higher voltage rating for a better safety margin and capacity for better operation. It is on a full wave rectifier. I don't think it has to have a low ESR but a good ripple rating at the 120 cycle DC from the rectifier. The voltage on the capacitor should be around 180 volts DC. So I would think 350 volts would be fine. C7 and C13 being changed to 100uf/50 volts was an update by Smartlabs. I did not find any other obvious other components when they where changed. I would use the 100uf/50 volt ones to replace the original 10uF/35 volt ones. They are the two in the switching supply output. So they should be a low impedance/ESR type. I have an original V1.0 with the reworked board to add the coil and second capacitor to make it a Pi filter from a capacitor only one. It has 10uF/25 volt ones. 25 volts is only about a 4-5 volt safety margin as the supply is around 20-21 volts.

V1.0 is the original hardware release. I would suspect it is failing. As any 2413S PLM over two years and a few months old. Is prone to power supply failing. Low Link Database Count is also an indication. Unless you only have a few modules. The count is low.
