Key differences between Heiman Smart CO Alarm and X-Sense Wi-Fi Carbon Monoxide Alarm
A summary of selected recorded differences between these smoke & co detectors. Check the full specification table below for details and conditions.
Feature differences among your selected devices
- 2.4 GHz Wi-Fi (connectivity): Heiman Smart CO Alarm — No; X-Sense Wi-Fi Carbon Monoxide Alarm — Yes (IEEE 802.11b/g/n).
- Screen (display): Heiman Smart CO Alarm — No; X-Sense Wi-Fi Carbon Monoxide Alarm — Yes.
- Automations (features): Heiman Smart CO Alarm — Yes (Triggers smart home actions when CO is detected); X-Sense Wi-Fi Carbon Monoxide Alarm — No.
- Alexa (integrations): Heiman Smart CO Alarm — Yes (Via Matter over Thread); X-Sense Wi-Fi Carbon Monoxide Alarm — No (X-Sense confirms its smoke and CO alarms do not work with Alexa: only the AS05 and AS08 security kits are Alexa compatible, and Alexa's API has no smoke or CO alarm type anyway).
Specifications to check side by side
- Thread (connectivity): Heiman Smart CO Alarm — Thread Border Router required; X-Sense Wi-Fi Carbon Monoxide Alarm — No.
- Battery Life (power): Heiman Smart CO Alarm — 10 years; X-Sense Wi-Fi Carbon Monoxide Alarm — 1 year.
Information still to confirm
- 1 of 37 comparison fields lack a resolved value for at least one selected device. Missing information is not evidence that a feature is absent.
- Check the full table and manufacturer documentation before ruling out a device.
These observations are derived from recorded catalog data and have not all been independently verified. Confirm details with the manufacturer before purchasing.
