Mobile thermometer?

Okay so this may sound weird, but I would like to add a thermometer to our baby stroller with a digital readout using a Wemos D1 Mini. I would power it via a charging brick which would double as a headlamp source, LED lighting source, and iPhone charger. It’s not necessarily an HA integrated component because it would be standalone, however, it would be nice to be able to also setup the D1 Mini to connect to WIFI when it’s close to home so it CAN connect to HA.

Is ESPHome the right tool to use to develop such a device?
