Are smart plugs safe for space heaters?

Technically yes, if the smart plug is rated for 15A/1800W and the heater draws less than that. However, many smart plug manufacturers advise against using them with high-wattage heating appliances. Always check both ratings and never use a smart plug with a device that exceeds its rated capacity.

Do smart plugs work during a WiFi outage?

Most smart plugs will continue in their last state (on or off) during a WiFi outage, but you can't control them remotely. Some plugs have a physical button for manual override. Scheduled timers may or may not work depending on whether the schedule runs locally or in the cloud.
