iNode MCU Relay - Bluetooth 4.1 and WiFi - for iNode Care Sensor

Programmable iNode MCU Relay designed to work with the iNode Care Sensor series. The module works wirelessly and supports Bluetooth 4.1 and WiFi communication. iNode MCU Relay is an element that enables the implementation of scenarios related to the broadly understood home automation - it can be used to care for the elderly, it allows you to turn on / off other devices after certain events, e.g. exceeding the set temperature or humidity, moving the sensor or changing its position .

iNode MCU Relay - Bluetooth 4.1 and WiFi relay - for iNode Care Sensor.

iNode MCU Relay with screw connection.

iNode MCU Relay is based on MicroPython ESP32 - a script interpreter for the MicroPython programming language (based on Python 3.4). For maximum user security, the MicroPython firmware is digitally signed and can only be replaced by OTA. The user can create his own scripts in Python and load them to the device. Everything is done using the iNodePY application. Free Python scripts are available on the support site . The device does not have a pre-loaded program - you should do it yourself.
