The old Blynk legacy app has been removed and support for the new Blynk IOT app has been added.
In the new updates, a new Blynk IOT application has been added and the WiFi connection has been improved.
iRelay changes are related to improved usage on iOS devices. The option to change the SSID and password has been added on all versions of the thermometer. High and low temperature alarm for SHT version, interval to send every 60 minutes & support for SENSOR SPY application is novelty.
Only system changes have been made to the iRelay classic firmware. iRelay Light now has the ability to DIY & make and convert to a temperature controller. In the management menu it is possible to switch on / off a special relay switch for heating and a special relay switch for cooling. To upgrade to a controller you need a relay module like this one. The default state is off. Only system changes were made on the thermometer. Firmware site
The new upgrade allows you to convert a classic OLED thermometer into a WiFi temperature controller like the V4. In particular, you can control the heating and cooling relay. The initial state of these relays is switched off. To upgrade to a controller you need a relay module like this one.
Due to frequent inquiries about the white color of the device housing, white devices are also available from today. When querying, it is necessary to specify the color immediately, since the standard color is black.
The Nautilis thermometer has the biggest change in its capabilities. In major code changes, it can now send the temperature to services other than Blynk Legacy at a given interval. BrewSpy, Brewfather and Grainfather supported this idea and enabled the development of their applications as well. The code will continue to be upgraded. There are now 2 versions of the thermometer available – Classic and Light versions. The difference is in the built-in screen.
Several improvements to iRelay have been underway over the past month. The latest is the ability to receive 2 Spindles on the BrewSpy app. Also, in cooperation with the team from BrewSpy, it is possible to send temperature data from iRelay to their mobile application as well as the web app.

11/05/2021 Firmware 6.4.9 -The NTC clock was discontinued because in some countries of the world the server was not supported during or the connection took too long, and this affected the Relay processor itself. New features have been added to the previous options (Displayless operation with LED lights only, different display type). Corrected ABV and ATT conversion when using the conversion option from P to SG.

07/01/2021 Firmware 6.4.2 -In the relay management settings you can make a conversion from P to SG. This refers to relay, while the application receives the values sent by iSpindel and for conversion it is necessary to do the same on the application you are using.
06/26/2021 Firmware 6.4.1 -In the thermometer settings, you can select the unit in degrees C or degrees F.
06/24/2021 Firmware 6.4.0 Download -In the settings you can select the unit in Plato or SG degrees. The default unit is SG. You can select a different unit for each hydrometer.

12/28/2020 Firmware 6.2.9 Download Displays the percentage of battery next to the remaining voltage. The values in the percentage formula are: 4.2V for Voltage.max and 3.3V for Voltage.min. The percentage is also visible on the local website and can be sent to the Blynk app via a virtual pin.It is recommended to calibrate the battery and change the correction factor before using the iSpindle. By default, ispindel batt factor is 191.8. You can adjust it by this formula: (displayed voltage / measured voltage) * current factor (191.8) = new factor
The new factor should be between current factor more or less 20%.
