The commands are of the form tcc set weather sectrusstemp=3D-25.7, airtemp=3D10.8, wspeed=3D15.3, wdir= =3D37.3, pressure=3D73006.941, humid=3D0.276 and right now they are indeed failing. I'm not sure why it was but I updated the opscore dependencies for that actor and now it seems to work. The TCC values that it shows are 14:14:39 apo.apo 2 tcc i AirTemp=3D10.80 14:14:39 apo.apo 2 tcc i SecTrussTemp=3D-25.70 14:14:39 apo.apo 2 tcc i PrimF_BFTemp=3D0.00,0.00 14:14:39 apo.apo 2 tcc i SecF_BFTemp=3D0.00,0.00 14:14:39 apo.apo 2 tcc i Pressure=3D73020.5 14:14:39 apo.apo 2 tcc i Humidity=3D0.28 14:14:39 apo.apo 2 tcc i TLapse=3D6.50 14:14:39 apo.apo 2 tcc i WindSpeed=3D7.0 14:14:39 apo.apo 2 tcc i WindDir=3D38.7 14:14:39 apo.apo 2 tcc i TimeStamp=3D5142665679.83 The only values that seems obviously different is the truss temperature which is not -25.7 and which sounds very wrong. It seems that sensor is not working correctly. Looking at the logs, in the past we have had cases of the apoActor not being able to write to the TCC (because the TCC was not accepting commands from tron) and that didn't seem to be an issue. Anyway, it should be working now and maybe it will make a difference ... Thanks, Jos=C3=A9 On Nov 3, 2021 at 08:33:53, Russet McMillan wrote: > 71787 pascals converts to 21.2 inches of mercury.
