loganjw Posted November 5, 2012 Share Posted November 5, 2012 I've tried many time to get this thermostat adapter working again. It used to work until I wiped my ISY clean and started over. I have two of these in my home and one works just fine but the other always fails with this error and "Failed writing device link". The adapter appears in my ISY but with the exclamation point icon. I can actually change the thermostat's setting in the ISY console and it will update the thermostat itself but then errors everytime. Since it won't complete setup, I can't access this thermostat from MobiLinc. I've reset the adapter but I'm guessing there's something in the ISY I need to reset/clear and I don't know what that is.

LeeG Posted November 5, 2012 Share Posted November 5, 2012 Run Tools | Diagnostics | Event Viewer with Level 3. Right click thermostat node and select Query or Write Updates to Device if there are pending updates to link database. Post the event trace. Being an RF device it sounds like the failing thermostat is not in reliable RF range of a Dual Band device. What does Help | About show for Firmware and UI levels? What is the thermostat type?

loganjw Posted November 5, 2012 Author Share Posted November 5, 2012 The Dual Band device is about 4' away. When this previously worked, it was in the same place. My ISY and access point have moved but they are on an adjacent wall to the dual band. I am running version 3.1.17 (firmware and UI) and have not upgraded due to the difficulty in upgrading from a Mac. The adapter is the 2441V and I believe revision 2.2.

LeeG Posted November 5, 2012 Share Posted November 5, 2012 The 2.2 adaptor has been replaced several times. It was initially replaced with a 2.2R to resolve some communications problems. I think the latest firmware is up to 2.5. The latest level is very likely I2CS which requires 3.2.6 Official release or 3.3.3 Beta to get I2CS support. I understand that Mac wants to unzip the download by default but there are ways to get a file downloaded without that automatic unzip. I’m not a Mac user but I thought there was a browser option to download without the automatic unzip. The commands sent to the thermostat adaptor get no response. Either the adaptor is not reacting or not in range of an RF device. Being 2.2 you could try a factory reset and Restore Device but that has no chance of working if not in RF range of a Dual Band device. Link to comment Share on other sites More sharing options...
LeeG Posted November 5, 2012 Share Posted November 5, 2012 One option is to swap the adaptors since one works and one does not. Either the problem will follow the adaptor or remain with the physical location. If it follows the adaptor the adaptor has a problem. If the failing adaptor works in the other location there is an RF issue at the current location. I meant to note in my earlier post, this is not an ISY question. The ISY is issuing the first command in the sequence to write a link record. The command is correct. The adaptor is not responding at all to the three attempts to execute the command.

loganjw Posted November 5, 2012 Author Share Posted November 5, 2012 I swapped access points, moved them around and tried and still no good. I did your suggestion and swapped adapters and bad thermostat still doesn't work. The adapter seems fine though as it works on the good thermostat. I realized earlier that when the adapter originally stopped working is when I moved the ISY itself, not when I wiped it clean. I don't understand why it matters, but I moved the ISY to another wall and outlet and everything is working again. Does the ISY's access point interfere with the RF access point if they're too close? Thanks for all your help! Still can't get the upgrade to work but I can deal with that later. Link to comment Share on other sites More sharing options...
LeeG Posted November 5, 2012 Share Posted November 5, 2012 A Dual Band PLM should have no impact on Access Points. All Insteon RF communication is automatic and autonomous. Applications such as the ISY have no control of the RF aspects of the Insteon mesh network. I am wondering if moving the ISY PLM before had an effect on phase coupling. Might try doing the 4 tap Set button test and see if the Access Points are in RF range of each other and on opposite phases. Can check the PLM LED at the same time to see its phase relationship to the Access Points. Link to comment Share on other sites More sharing options...
