Insteon: Bad data received

I can’t seem to pin down exactly why I am seeing the following in my logs:

==> /var/log/openhab2/openhab.log <==
2018-11-02 02:42:33.450 [INFO ] [g.insteonplm.InsteonPLMActiveBinding] - Item: GarageEntry_Lights got command ON
2018-11-02 02:42:33.451 [INFO ] [onplm.internal.device.CommandHandler] - LightOnOffCommandHandler: sent msg to switch 34.87.24 to on
2018-11-02 02:42:33.451 [INFO ] [onplm.internal.device.CommandHandler] - Sending message to 34.87.24
2018-11-02 02:42:35.981 [WARN ] [steonplm.internal.message.MsgFactory] - got unknown command code 0x34
2018-11-02 02:42:35.981 [WARN ] [ding.insteonplm.internal.driver.Port] - bad data received: got unknown command code 0x34

The switches fail to respond to my commands. Oddly though, one switch is reasonably reliable. At other times they might all work but probably less than 20% of the time.

This only occurs with Insteon devices in my garage. I suspect that it is not receiving the entire message since the unknown command code always appears to correspond with the first byte of the Insteon device address. In this case 0x34. I suspect tht my garage is not a good environment for my Insteon devices in that there is a single circuit to it hence there are no other devices on that circuit outside the garage. Furthermore, I have a narrow corridor to my garge that has a fire door, hence metal, at the end of it. This likely blocks any radio signals. Otherwise they would need to travel outside through two walls.

My two phases are connected via Insteon repeaters and the Insteon switches in my house work fine.

Any ideas? Is my garage a lost cause and I should look for an alternative solution?

Sounds like too much noise. I have found the new dual band (RF and powerline) switches do better than the powerline only switches and using repeaters…

This would appear to be the case. For the purposes of testing, I moved my hub into the garage and now everything works fine. I don’t mind keeping it in the garage but I will need to check what the acceptable operating environmental temperature is for the hub.

I have left my in my cabin at - 30c. No problems :slight_smile:

Thanks. Good to know. I get nothing like that cold where I am. Perhaps -8 C at the worst in my garage.
