Ciao a tutti sto costruendo un Idrometro con con sonar della Maxbotix e Arduino UNO Wifi rev.2 che invia dati a un cruscotto della Ubidots. Fino a qui tutto ok funziona benissimo e riesco a inviare i dati a intervalli regolari. Ora vorrei che il mio Arduino UNO wifii rev2 mandi un allarme su telegram tramite bot quando il livello raggiunge la soglia di attenzione e quando raggiunge il livello di l'allarme. vi allego lo script che funziona, ma manca la parte telegram, ne ho provati diversi ma non riesco proprio a farlo funzionare. Grazie
