Thank you for the information.

Glad I may have helped. One thing I may not know. Is what Smartenit did to their daughter board. So my memory size and speed. Along with the F1 fuse may not apply to theirs. As I believe it has a optional RS485 interface.

The earlier Smartenit units where built on a base 2412 main board . Then on a base 2413 main board when the 2412 was discontinued. The 2412S did power the ISY99i or ISY994i through the Serial Port connection. The same base daughter board was used in the 2413S. The F1 fuse was not installed. So it did not power things through the serial port connector. The fuse was 400mA if memory serves me. I am not too sure how much extra current capacity a 2413 main board has. So how well it will power the ISY99i or ISY994i is not known. Also not 100% sure the DC is total y isolated from the power lines in a 2413 main board. From your description it very well could be the extra power used by the ISY994i is overloading it. Also the memory on the 2412S daughter board was slower and depending on the age. Had a 417 or ~ 2000 Link Database on it. Depending on its age you may have a small Link Database . It will also have a slower memory access speed over the 2413S daughter board. I don't have any information on the differences between a 2412 daughter board and what Smartenit may have on their added daughter board. You could try disconnecting F1 if it has one and powering it through the external wall wart. To see if anything changes. If the PLM and the external wall wart are trying to power the ISY994i. The higher voltage will power it. Since the PLM voltage is higher. Even if both are connected. Most likely the PLM is still powering it.

It probably is the PLM. If you care to read a real long thread on the PLM issues and how some of us repaired theirs. https://forum.universal-devices.com/topic/13866-repair-of-2413s-plm-when-the-power-supply-fails/

If it is over two years and a few months old. That would be another factor in determining it has failed. Along with the LED on the side sometimes being dim or RED.

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.

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.

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.

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.

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.

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.

Thanks for the information. Since it looks like the 2411T is on its way out. As the price is now 9.99. I suspect when it is gone. There will be no more. So another device would be needed. The 2411R receiver is no longer being offered for sale either.

I am also disappointed that the Alarm and Siren Modules are not in going to be available. Until a version of 5.? is a Released version or even a fairly stable Beta. I believe they date back even further than the Motion Sensor II. Part of this is Smartlabs problems. Old management didn't seem too willing to share things. Even though I suspect the UDI line of products. Was helping Insteon to be more widely used. I even have a spare base model ISY994i and PLMs to play with but a Alpha is not my cup of tea. Hope new owners Richmond Capital Partners makes thing better but I suspect it may even get worse. They seem to want to to big things with internet connected things. From what their press release indicated.

As pointed out in the bulbs users manual. You can't Factory Reset a Insteon Bulb. As it has no linking button. Manual mentions Insteon RF and Power Line. Though my memory says it is RF and you may have to be close enough to the PLM or another Dual Band module to access it. Manual not too clear on linking mode and possible timeout. You may want to move step 1 to between 5 and 6. The bulb may only stays in the linking mode. For a set period of time.

The relay output on the UPS. Is it also a dry contact? The users Quick Guide has this in it also. The module has two Opto-Isolated inputs. I1 and I2. You can connect the I1+ and I2+ to the +5 volt terminal of the module. Then the magnetic switch between I1- or I2- terminals and the ground terminal. Then the UPS relay output between the other I1- or I2- terminal and ground. If not too clear. Please ask for more data. Can't help with programming. It also has two Digital Inputs I3 and I4. If you have to have more dry contact inputs. The Guide show you how to use pull up resistors.

As far as I have seen. No release date given. No Beta only Alpha at present. I have had no big issues with a UDI Beta and would install one. I am Leary of an Alpha. Seeing some of the reported issues presently being addressed.

It is not presently supported in released software. Same for the short lived Alert Modules. I have also been waiting since they where released as mine where early purchases. Have not tried the Alpha 5 yet. Though I do have a spare ISY994i and PLM I could play with.
