When I use the program related to this technology, the device gets hot, it seems to consume a lot of power, and for this reason, it gets hot. Does this connection really consume low power? so why device gets hot after few mins

What program do you use? When the device gets hot, is it sending packets all the time ? For the update readme, we remove the low power, because currently we didn't open the wifi power save, that is the RF is always on. We will add wifi power save function in esp-now in the future. If your device sends packets every few minutes, you may make the device in deep sleep after sending and wake up before the next sending to achieve low power.
