Thanks for information I use before \>25 for outside range to limit false positive. Is it possible to set a bigger limit than 10 for this setting ? Since this limit, I can’t found a settings with no error and it’s very frustrating for my flows based on presence. Thanks a lot (I use nut mini and cheap AliExpress tags) ---

That setting has the purpose to cancel out false positives. Today the false positives are way more frequently by reasons unknown. We should investigate why this is happening, not trying to filter out more false positives. ---

How can you set 20 in the lest parameter Impossible since few weeks (limited to 10) I have tried lot and lot of settings, and never had a really reliable configuration Lot of false positive, from 3 to … Too many Impossible to activate / deactivate alarm automatically with this since this update, ant others flows… ---

A few days ago, Homey has released the version 7.0.0 of its firmware. After running the Beacon app in debug mode with various app settings, I can say that the BLE scanning has improved compared to v6.1.0. However, there are some caveats. 1. The BLE scanning duration in firmware 7.0.0 is always 5 seconds ([as stated by official updated documentation](https://apps.developer.homey.app/wireless/bluetooth)), regardless the value you enter in the `Discovery timeout (default 10)` Beacon app setting. What does it mean? It means that the interval is quite short and the likelihood of a beacon not being discovered in such a short interval is quite high. The consequence is that the parameter `Verification amount outside range (default 5)` should be set to a high value (even up to 10) for avoiding false “inside-range → outside range” events. 2. The time between two consecutive BLE scanning can be shortened as much as you like. However, if that time is shorter than 15 seconds, Homey does not perform a new scanning but, rather, it returns immediately the result of last scanning. This alters the beacon detection logic in Beacon app. Thus, it is strongly recommended that the value of parameter `The delay between reading sensor values in seconds` is never less than 15. On the other hand, there is no reason for its value to be greater than 15 as this would slow down the beacon detection logic in the Beacon app. In conclusion, I would suggest the following parameters in Beacon app v1.3.x with Homey v7.0.0: **15.5.1.10**. ---

I’ve found out that the settings are cached also. So changes on the interval are not used directly. I’m currently investigating a fix for this. ---

I assume a Homey restart will empty the cache? As workaround? ---

I’d also like to higher this number if possible, Sinds I’ve a lot of false positives. And that in a 75m3 apartment with homey pretty much in the centre. I now use wifi to detect absence and beacon to detect presence. IF smart presence detects a person left, AND beacon is false Then set person away. IF beacon becomes true AND person is away THEN open lock, set person as home ---

My log. Using **15-5-1-10** From my set of 4 beacons, it’s mostly the ‘Pe\_8erdeur’ beacon which gives false positives. All 4 on new batteries. ‘Pe\_8erdeur’ and ‘Pe\_auto’ lie 4 to 5m away from Homey; ‘Gast’ and ‘Lief’ 10 to 100cm. So _the distance to Homey_ is very much a factor here (and depends on the device brand, see screenshot) ![Screenshot_20210620-132514_Chrome](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/c/1c845b21615b1934d0794400c5ba4cf6aab68a47.jpeg) Logs ```auto 2021-06-19 02:08.52.050 Flow Peter away > Beacon v Pe_auto 689E 2021-06-19 02:29.23.692 Flow ELSE Peter Away > beacon v Pe_auto 689E Gecancelled 2021-06-19 02:52.12.520 Flow ELSE Peter Away > beacon v Pe_8erdeur 1DAB Gecancelled 2021-06-19 03:59.02.411 Flow ELSE Peter Away > beacon v Pe_8erdeur 1DAB Gecancelled 2021-06-19 04:02.22.232 Flow ELSE Peter Beacon_8erdeur thuis J/N: true 2021-06-19 04:20.37.626 Flow Peter Away > beacon v Pe_8erdeur 1DAB 2021-06-19 04:50.01.189 Flow ELSE Peter Away > beacon v Pe_8erdeur 1DAB Gecancelled 2021-06-19 06:48.43.677 Flow ELSE Peter Away > beacon v Pe_8erdeur 1DAB Gecancelled 2021-06-19 06:56.03.147 Flow ELSE Peter Away > beacon v Pe_8erdeur 1DAB Gecancelled 2021-06-19 07:21.06.457 Flow ELSE Peter Beacon_8erdeur thuis J/N: true 2021-06-19 12:05.06.109 Flow ELSE Peter Beacon_8erdeur thuis J/N: true 2021-06-19 12:54.34.157 Flow Peter Away > beacon v Pe_8erdeur 1DAB 2021-06-19 12:54.43.390 Flow ELSE Peter Beacon_8erdeur thuis J/N: false 2021-06-19 12:57.11.486 Flow ELSE Peter Away > beacon v Pe_8erdeur 1DAB Gecancelled 2021-06-19 16:04.14.300 Flow ELSE Peter Away > beacon v Pe_auto 689E Gecancelled 2021-06-19 20:11.47.988 Flow ELSE Peter Beacon_8erdeur thuis J/N: true 2021-06-19 20:15.07.240 Flow Peter Away > beacon v Pe_8erdeur 1DAB 2021-06-19 20:57.50.186 Flow Gast Beacon thuis J/N: false 2021-06-19 20:58.10.256 Flow ELSE Gast Beacon thuis J/N: true 2021-06-19 21:30.35.613 Flow Gast Beacon thuis J/N: false 2021-06-19 21:30.55.306 Flow ELSE Gast Beacon thuis J/N: true 2021-06-19 23:32.52.633 Flow ELSE Peter Beacon_8erdeur thuis J/N: true 2021-06-19 23:54.24.401 Flow ELSE Peter Beacon_8erdeur thuis J/N: false 2021-06-19 23:55.33.533 Flow ELSE Peter Away > beacon v Pe_8erdeur 1DAB Gecancelled 2021-06-19 23:55.34.569 Flow ELSE Peter Away > beacon v Pe_8erdeur 1DAB Gecancelled 2021-06-19 23:55.36.223 Flow Lief Beacon thuis J/N: false 2021-06-19 23:55.58.847 Flow ELSE Lief Beacon thuis J/N: true 2021-06-20 00:24.29.168 Flow ELSE Peter Away > beacon v Pe_8erdeur 1DAB Gecancelled 2021-06-20 00:44.09.731 Flow ELSE Peter Away > beacon v Pe_8erdeur 1DAB Gecancelled 2021-06-20 01:06.28.969 Flow ELSE Peter Away > beacon v Pe_8erdeur 1DAB Gecancelled 2021-06-20 01:10.35.276 Flow ELSE Peter Away > beacon v Pe_8erdeur 1DAB Gecancelled 2021-06-20 03:44.03.838 Flow ELSE Peter Away > beacon v Pe_8erdeur 1DAB Gecancelled 2021-06-20 06:34.22.111 Flow ELSE Peter Away > beacon v Pe_8erdeur 1DAB Gecancelled 2021-06-20 08:41.11.090 Flow ELSE Peter Away > beacon v Pe_8erdeur 1DAB Gecancelled] 2021-06-20 12:02.03.799 Flow ELSE Peter Away > beacon v Pe_8erdeur 1DAB Gecancelled ``` From the BLE overview, you can see the most often flipping beacon’s (1DAB) signal is below -65db.
