This project was created as a cheaper alternative to climate meters for server rooms.The system is aimed at using the snmp protocol for temperature control in server racks.Suitable for interaction with monitoring systems supporting the SNMP protocol such as PRTG network monitor, Zabbix and the likeThe button is used to reset the settings. Pressing this button when the device is turned on allows you to reset the settings to default mode.The default mode is set automatically after the firmware if there was no data in the EEPROM memory.Default mode means launching the APK of the access point with the address 192.168.4.1 SSID:TERM-SNMPSNMP Community RO: PublicThe SNMP OID consists of a prefix .1.3.6.1.4.1.2020.1. , which can be changed in the settings, next .1 - degrees Celsius .2 - degrees fahrenheit, which is the temperature sensor numberthe resulting value must be divided by 100example: .1.3.6.1.4.1.2020.1.1.2 - displays the temperature in degrees Celsius of the second sensorThe numbering of the sensors is displayed on the first page of the setup Supports up to 10 sensors
