Wi-Fi needs more power in comparison to Zigbee and BLE, so there's no way the Shelly H&T could run for an extended period on a single coin-cell battery. Instead, they connect directly to your access point and can either be configured using a built-in web server, or more likely using an app. And because you are using ESPHome, you arent restricted to just using one sensor. Track airborne toxic chemicals (VOCs), humidity, and temperature levels in your space. Even though there aren't many models available, I have done some research a put together a list of the best Wi-Fi temperature and humidity sensors that integrate with Home Assistant. The generic_thermostat platform we used, created a combined entity from the switch and sensor called climate.living_room. There are 3 different display configurations which you can cycle through by double-tapping the button on the top. Whatever you device, range and placement will be crucial to maintain stability, as Bluetooth has a very low range in a crowded environment (Wi-Fi, ZigBee etc.).

I set up a Zigbee integration with a Sonoff Zigbee Bridge and installed a few add-ons, including Node-RED, File Editor, Mosquitto broker, and Samba. We define the Sonoff basic switch as heater, the Temperature sensor as target_sensor. Got [switch.sonoff_1000cf8fc2]. It also comes with a lanyard that can be installed with a bit of difficulty so that the device can be hung by it. A quick glance can tell you if its too warm or cold, too dry, or if you need better ventilation in the room.
