Hi, I have a Homey Pro (Early 2019) box with the SONOFF ZIGBEE application, and when I add an SNZB-02D Sensor I encounter problems because it does not take into account any settings (decimal, offset, etc.) even if in the console Homey the parameters seem validated. I tested with several SZNB-02D sensors with the same result. Attached you will find screenshots and the result of the Zigbee interview after changing the settings. I would really like to be able to change the temperature intervals. ![first_change_parameter](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/4/24c90f0ea91028a17285f1243132b19c269b1e74.jpeg) ![Not_Offset_Apply](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/4/042dbf8852e4a2a6d4d6ac5ff1f11f01032f1106.png) ![second_change_parameter](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/0/300b388f2d797cbd77c31556438adf05a72c440e.jpeg) ![Statut_after_first-change](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/b/4b0eeff909f8a38ae39351611c46144873ddc7ea.png) ![Statut_after_pairing](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/d/3da2ab76d45002b48ded7c46cf6ceee3c415c7a9.png) ![Interview_screnn_after_restart_app-Change_not apply](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/4/24b5d09fc1891f073ee0226aa1fc98411e72752d.png) ![Restart_App](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/7/b7e49a57a209b806103ef0a68e8e1d90dc5a9e20.png) ![Third_change_parameter](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/e/2e2c373afb5a67056be70703fd2b529666cf3967.png) ![Zigbee Devices](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/6/9/69c1ea4c9ec1f7ad92e49f0c5c973eb271a477bc.png) Thank you for your prompt response. ---

Are you waking the device up before changing the settings (and keeping it awake until they are set)? ---

how do I know that the sensor is awake and how do I keep it that way? Does it take long to apply settings? because I regularly press the sensor button, is this enough? For the moment I still haven’t managed to change the intervals. ---

Pressing the pairing button will usually wake it up. Once it’s awake, apply the changes while pressing the button every second or so, to keep the device awake. ---

I still can’t do it, and I think that the sensor is not awake because the zigbee interview works well but the “minChange” parameter for example does not change but the new parameter is in Homey ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/f/8/f8e7d961193ade0b759340de4296201370c54955.png) With Interview : ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/0/4050c32fb0bf15aac3421cfb51a4c6f2d4e9970a.png) ---

You have to wait until the temperature changes, if I’m right. Why is the “Temp min. change” at ‘20’ (assuming it is in °C), doesn´t it in that case only report when the temperature changed by 20° or more? ---

Yes of course, I waited for the temperature to change, the result of the Zigbee interview clearly shows that the parameter was not modified. 20 means 0.2°C as explained below. Whatever the setting, I see no effect, is there an incompatibility between your Sonoff application and another? I bought 6 sensors with the certainty that I could configure them, do you have another idea to help me. For additional information, I also do not have the status of the battery going up. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/6/769d93e9d746be0b5b3f35c0175794e43b4e7f0f.png) ---

I don’t know if this can help you, but here is the code from the diagnostic report for the app that I just made. b1dd4010-0646-458e-b573-4d3bd5915438 ---

> [@kowalski.jerome](#): > > SNZB-02D You’re not alone as I searched for SNZB-02D in the official app topic, didn’t find a solution: [https://community.homey.app/search?context=topic&context\_id=36418&q=SNZB-02D&skip\_context=false](https://community.homey.app/search?context=topic&context_id=36418&q=SNZB-02D&skip_context=false) My advice would be to post your issue + Diag Report to the Sonoff zigbee topic (the developer also gets informed that way); Links to that topic and other support links can be found at the bottom of the homey.app store app page. ---
