Still waiting for my Mimo2 to show up next week. ordered it before I figured out a work around for my Mimolites.
I am assuming you are referring to Sig1 and Sig2.
With my 2 Mimolites I am getting inconsistent reporting from my Sig1 signal sometimes when manually opening or closing. Used as garage door controls.
I was able mostly fix it by putting:
secureCmd(zwave.sensorBinaryV1.sensorBinaryGet())
before a open or close command along with some logic to cancel the command if in the incorrect state in the DH.
Only issue I have not worked out is that they would still not display on a dashboard correctly sometimes if in the incorrect state until an open or closed command was sent.
I also found that unplugging power and plugging back in Sig1 would start reporting properly again for a few days.
Which indicates it is a faulty relay likely a static build up.
secureCmd(zwave.sensorBinaryV1.sensorBinaryGet())
polls the state of Sig1
I believe for Mimo2 you need these cmds for Sig1 and Sig2 (can't test it until it shows up)
secureCmd(zwave.sensorBinaryV1.sensorBinaryGet(), 3)
secureCmd(zwave.switchBinaryV1.switchBinaryGet(), 4)
