Which sensor model is less prone to false alarms?

Here you are,  take with a grain of salt as it Ai generated, but sounds relatively accurate to me based upon reading here and at Reddit etc. Amazing critters at some things.

Chatgpt's take;

Both SimpliSafe's original smoke detector and their newer combination smoke and carbon monoxide (CO) detector utilize photoelectric sensors to detect smoke. Photoelectric sensors are generally more responsive to smoldering fires and less prone to false alarms compared to ionization sensors. However, they can still be susceptible to false alarms caused by factors such as dust accumulation, steam, or insects.

SimpliSafe acknowledges that false alarms can occur with their smoke detectors and recommends monthly cleaning to prevent dust or debris buildup. This maintenance involves removing the battery, vacuuming the sensing chamber, and then replacing the battery. Additionally, it's advised to install the detectors away from sources of steam, like bathrooms or kitchens, to minimize false alarms. 

User reports indicate that false alarms have been experienced with both the original smoke detectors and the combination smoke/CO detectors. For instance, some users have reported multiple false alarms with the smoke detectors, even after following cleaning and maintenance recommendations. Similarly, there have been complaints about false alarms with the combination detectors. 

Based on available information, there doesn't appear to be a significant difference in the likelihood of false alarms between SimpliSafe's original smoke detector and their combination smoke/CO detector. Both devices require regular maintenance to minimize the risk of false alarms. If false alarms persist despite proper maintenance, it's advisable to contact SimpliSafe's customer support for further assistance.

Groks take;

Based on user experiences and discussions found on the web, the SimpliSafe new combo CO and smoke alarm appears to be less likely to produce false alarms compared to the original SimpliSafe smoke detector. Here's a breakdown:

Original SimpliSafe Smoke Detector: There have been numerous complaints about false alarms, often triggered by dust, steam, or other non-smoke particles. Users have reported issues like alarms going off in the early hours without any apparent cause, leading to significant inconvenience and even emergency services being dispatched unnecessarily. Some users have even disconnected these detectors due to repeated false alarms.

SimpliSafe New Combo CO and Smoke Alarm: This newer model has been described as having better technology to distinguish between actual smoke and non-threatening particles like those from burnt food. Users and SimpliSafe support have noted that this detector offers built-in protection against false alarms, although it's not immune to them entirely. The design helps in reducing the frequency of false alarms, though some users still experience issues, suggesting that while improved, it's not perfect.

From the available data, while neither device is completely free from false alarms, the new combo detector seems to have fewer complaints regarding this issue. However, the effectiveness can also depend on maintenance like regular cleaning and proper placement away from steam sources, dust, and cooking areas. 

Keep in mind that individual experiences can vary, and what works for one might not work for another due to factors like home environment or installation specifics. If considering a purchase, it might be beneficial to look into the latest user reviews or reach out to customer support for the most current feedback on product performance.

Given this, while the current data suggests the new combo might perform better in terms of false alarms, it's prudent to consider these observations with the caveat that long-term data on the new model is still accumulating. It would be beneficial to keep monitoring user feedback over time to see if this trend holds as the product matures in the market.

@captain11 the 2-in-1 Smoke & Carbon Monoxide Detector has a food-safe detection feature that was designed to ignore cooking smoke, like burnt bacon or toast. This feature should help reduce false alarms.
