Now that i have my globalcache serial device working and I can successfully turn my projector on and off i would like to query the projector status with a read of the serial port.
I have enabled 2 way but don’t know how to read from the device. I am on OH3 M4.
Define an item linked to the thing’s receive channel, then write a rule that looks for updates to the item.
Just to avoid issues you may want to upgrade. M4 was known buggy for many people & RC2 is now released.
I don’t see a receive channel to link to in the UI.
Thanks. I have updated to RC2.
Thank you. checking the show advanced now gives me the receive channel.
I have linked an item to the recieve channel and created a label card the sends the status command to the channel but i now get an error in the log:
Thing gc100_06:000C1E00AC76 has unknown channel type channel-type-sl-receive
You’re trying to send a command to the readonly receive channel?
Send the command to the direct channel.
