Spa Intex

Adds support of Intex Spa throught MQTT protocol. Current features: - Get water temperature - Set target water temperature - Control heater, blow Prerequisites: This application depends on Menno van Grinsven MQTT Client (https://homey.app/fr-fr/app/nl.scanno.mqtt/MQTT-Client) to communicate with a MQTT broker. You have to install and configure this application first (and configure a MQTT broker somewhere). The underlying communication between the MQTT broker and the SPA is done by a DIY object only. The details are found on the Github's jnsbyr/esp8266-intexsbh20 repository (https://github.com/jnsbyr/esp8266-intexsbh20). Note : This system is only compatible for these models: - Intex PureSpa SB-H20 - Intex SimpleSpa SB–B20 - Intex PureSpa SJB-HS - Intex PureSpa SSP-H (not tested) All the commands and measures of the Spa are available.
