Hi bigcake and xxDvDxx,

Can you please, on latest software, replace the Wireless_Sensors.ino file by the one included on the RAR file attached below, reprogram the receiver and report back if the reported issue is solved or not.
Thank you.

Hello, I did what you suggested replacing the Wireless_Sensors.ino file you sent , but it seem doesn’t solve the problem . I tried using a POWERBANK as power source just to be sure it doesn’t get any interference from the power line. As you can see on pics attached below, you can see that the temperature freeze when reach 0.1 degrees ( 3.00 am ) . Then in the morning I manually did a Reset to restart the system and its refresh all data in the right temperature. 
I added a temperature sensor and humidity sensor compensation in the previous update , just in case you want as extra info .

Sorry if I haven't been able to answer earlier but I've been very busy with my job.
However, I did several tests but I confirm what xxDVDxx said: the problem with the new Wireless module downloaded on January 1st had the same problems.
