Be careful not to get the version wrong

In March 2026, Heimann replaced the HS1SA-E by the HS1SA-E-PLUS It is sometimes written as HS1SA-E and this is where it becomes difficult to follow. Both models are physically identical apart from their labels which both display HS1SA-E.

Both comply with EN 14604 but they have nothing to do with Zigbee features and exposures.

The old version is sold between €16 and €17 (Domadoo or Amazon) while the new version has a public price of €37.99.

Update 18 April 2026: Amazon has just launched its €34.99 sale

• I am testing the smoke detector Zigbee Heimann HS1SA-E (old model)
• I am testing the NEW smoke detector Zigbee Heimann HS1SA-E-PLUS (new model)
• Comparison Smoke detectors/heat Zigbee

We can distinguish them because the boxes are not the same.
