Hi Guys, Need a bit of help with a group turning on during the night. Happens about once every 4 weeks roughly As you will see, the bath fan turns on at 4:55am, I presume object means unit 50 instigated it? The decoded value is strange. 72>73 (20s), 60>73 (20s), 48>73 (20s). Then what's the object data? Cheers, Chris.
