[docs] def power_get(host, port, index): assert port is None index = int(index) host = f'{host}/status' r = requests.get(host) r.raise_for_status() # Basically, an HTML page is returned, whose body contents are like: # <div id="state">ff</div><div id="lock">00</div><div id="perm">ff</div> # We're interested in the value of state div - 'ff' above. And the # status is basically the corresponding outlet bit index. So, outlet # 1 is the 0th bit, with 1 for ON and 0 for OFF. statuses = re.findall(r'state">(\w+)<', r.text)[0] return bool(int(statuses, 16) & (1 << (index - 1)))
