There are a few alternatives you could consider as well. For instance: if the IoT widget has a low power draw, as the ESP module would, power it from the low voltage side of the transformer. You'll need a little power supply board that can take about 16 VAC in and put out whatever DC voltage your circuit requires. (HVAC circuits use 24 VAC, but doorbells in ...
