The old Blynk legacy app has been removed and support for the new Blynk IOT app has been added.
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 firmware version allows iRelay thermometer data to be sent to the UbiDots application independent of iSpindel data. Firmware site
Did you know that every Nautilis WiFi thermometer can be iRelay? How? Just upgrade the firmware and a miracle will happen 🙂 The only thing is that the thermometer, because it does not have an external antenna, will have a weaker signal and will not have the power to receive data from stainless steel fermenters. But if you don’t have a problem with that this is quite a handy option. Of course, the possibility of switching from iRelay to a thermometer is also valid.
