I have the fan in the forced air system set to circulate so it comes on for a few minutes every 15 minutes or so. the room with the sensor is easily the coldest in the house being the basement north west corner so slightly warmer air gets blown in when that happens. if the air is warm enough the room gradually climbs as happened last night. If the air isn't the room gradually drops like happened in the first graph.
I picked up 100 meters of cat 3 today and will put the second sensor in the room with the wood stove if I get a chance tonight. It'll be nice to see multiple temps logged and see how the rooms are different.
