I do not think so. It would help only if the Access Points are not able to effectively couple the two 120v legs. The purpose of the hardwired coupler is to pass Insteon messages that are already on the powerline from one 120v leg (phase) to the other. The same function the Access Points perform. In addition the Access Points also provide the bridge between the powerline and RF only devices. I would expect other Insteon network issues if the Access Points were not coupling effectively.

 

Installing the hardwired bridge will not hurt anything.

I saw these on ebay, not hardwired but with antennas, Signalinc RF #2442. Thought that they may help, but I see they are discontinued at Smarthome so they must not serve a useful purpose any longer.

 

Thanks again and I do appreciate all your help.

2442 SignalLinc RF is the original coupler type device.

It uses a different RF frequency so it can only talk to another 2442. It also will not receive any signals from Insteon RF device or Dual Band devices.

If memory serves me they also do not process Extended Insteon messages so I2CS device are another problem.
