Usage of ESP32 chipset family for periferal alarm system

[rawsoc]

Hi, I'm building a battery powered wireless peripheral alarm system and I looking for a transmitter device to integrate with Home Assistant.

I think ESP32 can be used for this purpose, but I have doubts about the power consumption.
To make the battery last for a long time (at least 2 years) I should keep ESP32 in deep sleep mode and wake it up only in case of signaling.

In this mode I have no possibility to understand if ESP32 is disconnected or has network problems, it's right?

Are there other hybrid modes that keep the wifi link active but at the same time consume very little?

Thanks

You would have to wake up from deep sleep periodically to send a "heartbeat" signal to make sure device is still functioning.
