Being a retired HVAC automation tech I find the Sense/Kasa combination an interesting way to analyze and control our electrical devices. Case in point is our two stage 90+ gas furnace. Sense found the blower motor fairly easy. But the draft inducer or igniter not so much. So I installed a HS110 on the furnace to see what’s going on. In the following images there is a leading and following 10W reading that is the transformer/circuit board/thermostat load.
Following is single stage operation.
This is two stage operation.
I have a steam humidifier that cycles the fan. This view shows humidification with a single stage heat cycle. Furnace only. Sense has identified the humidifier as a separate device.
My initial realization was that it’s no wonder that Sense never identified the furnace beyond the fan motor considering the limitless variations of this system.
Where do I go with this;
- Next winter I will analyze the 1 stage vs 2 stage vs humidification to find the best comfort level at an economical operation.
- The furnace/thermostat have a dehumidification function. Going to analyze this to see what operation is the most economical operation vs comfort. Sense has also identified the A/C condensing unit as a separate device.
