Is your PLM a model 2412S or 2413S? 2412 had less than 500 links. Although I’d say it’s a record if you have still have a working 2412.

I kinda remember some older PLMs may have only had 500 links but very vague memory. The ones I recall all had 1000 links. Regardless, no new serial PLMs exist right now. You can check current link count with Admin console on ISY. Tools Diagnostics Show PLM link table. The issue is if you have any Insteon traffic it will reset pointer and screw up the count. If you can make sure nothing sends an Insteon signal inclining motion sensors, it’ll be accurate. Run command a few times to see if you get same count more than once. I actually took my ISY, PLM and a laptop to a neighbors with wired Ethernet once to get an accurate count.

My Insteon network is very similar to yours in size and device composition. Many of my switches go back to about 2009 and like you I have bought a stock of dual band devices to replace them as they fail. I have about 7 access points and 5 of them were the model two versions that someone mentioned. I noticed reliability of some devices failing. Did a bit of checking and found that 4 of 5 access points had failed. I repaired them using new capacitors and reliability was restored. Model 2 have a green LED and it will be dim or off if it’s dead. Too late to say long story short but I only posted the repair link in regards to the access points MrBill mentioned failing. With 150 devices and I’m sure many scenes you may be bumping up against the PLM link limit. If you’re on version 5 and use polyglot, I’d install the inventory nodeserver to see if you’re getting close to limit. Additionally, you might restore PLM with existing PLM still in place which I believe reclaims entries. It only updates PLM with fresh list stored in ISY and does not need to update other devices. Something I read once made me think it’s a sparse list data structure in PLM vs dense list.

Was just posted on another thread. Best I’ve seen and common wisdom is replace all of them. https://www.rototron.info/insteon-plm-repair-tutorial/

I’ve had this happen a couple times. In my case the ISY appeared to be stuck in linking mode. I rebooted and then power cycled it but I think in the end the ISY just timed out of linking mode. I pulled air gap on new switch so not sure what finally fixed it. I then starting link mode again after I factory reset the switch.

See page 13 of following manual on how to set reversing valve mode between O/B so it will cool. http://cache.insteon.com/documentation/2732-xx2-en.pdf

In the thread you listed, I posted about testing a 2413U and it works in same configuration as the wireless PLM.

GPIO nodeserver looks like it but I haven’t used it. Also a relay board like: https://www.amazon.com/dp/B00DR9SE4A/ref=cm_sw_r_sms_apip_6LmWveA9NhssY There are smaller versions depending on number of relays needed.

Before I start, the following is a kludge I’l used years ago. Way before nodes, polyglot and Polisy. I took RF remotes apart and soldered the button contact points to relays. I used an IR controlled relay board but same could be done with a RPi relay board. When IR or network command for RPi is sent, it momentarily close the relay which mimics a button press. If you can hide setup and cost of extra remotes is not an issue, it works great but is far from elegant. I know nothing about zigbee and interfacing to it so Keep looking for better but as a backup…

You are correct.

I wrote following conservative guide to move from 4.x to 5.x https://forum.universal-devices.com/topic/26381-upgrade-from-473-to-5015a-task-list/

Agreed. Michel and UDI are the very best I’ve ever worked with!

Is your ISY backup file corrupt or the SD card?

MrWorf, Thank you for trail blazing. As we have suspected, it works with a 2413U. I added a LampLinc to my backup ISY and then turned it off and on several times. See images.

Typo. Lol

Fabulous! I hope to get solder gun out and hook up to duplicate with the2413U. I had been reading about boot times so it’s great that you’ve found excellent resources to get rid of extra processes.

Congratulations! I’ve got all the parts today. I’ll work to duplicate using the 2413U in next couple days.

Sounds good. The 2413U as suspected does not provide any power. Be interested to see if you can get power from ISY.

Fantastic! I’m going to start work on seeing if I can apply this to the 2413U. One question … which RS232 to TTL adapter do you plan to use? I plan to use onboard RPi UART so I don’t think I’ll need it but it may make it more reliable. Edit. I ran it on rpi3 and it found the internal serial ttyAMA0 and the usbserial ttyUSB0 of the 2413U! The breakout connector you listed will be here tonight and I’ve got a backup ISY. I’ll add a lamplinc to it for a very simple test.

Both USB ports can power the RPi Zero wireless. The one marked power does not have data pins.

Gotcha. I found a few cases to 3D print to keep it contained.

That’s what I thought. I haven’t looked yet but feels like PiZero should be able to get power from the PLM USB port. Also, I look to see if any cases for pizero have been uploaded to thingiverse.com to modify or use as is.

Congratulations. Do you think the same would apply to a 2413U dual band usb PLM? I ordered one and about to set off on what you’ve done for this device. I’ll wait to see GitHub!

You can’t replace since they do not match. You can look in the admin console when you select the device and it will display which scenes they are a controller and a responder. Even better you can generate a topology in a document. In programs you can find by the device name. I’d copy all programs to clipboard and then paste into a text document. Then you can locate each program with the device name after deleting them and then fix programs like before likely with the same name.
