            @Skorpionbird looks like a breaking change in onoff.js module…

            latest fs has started enforcing callback on async operations.

            onoff write needs to be fixed like read

            Gpio.prototype.read = function (callback) {
              fs.read(this.valueFd, this.readBuffer, 0, 1, 0, function (err, bytes, buf) {
                if (typeof callback === 'function') {
                  if (err) {
                    return callback(err);
                  }
            
                  callback(null, buf[0] === ONE[0] ? 1 : 0);
                }
              });
            };
            

            current write

            Gpio.prototype.write = function (value, callback) {
              var writeBuffer = value === 1 ? ONE : ZERO;
              fs.write(this.valueFd, writeBuffer, 0, writeBuffer.length, 0, callback);
            };
            

            try editing MagicMirror/node_modules/onoff/onoff.js
            and changing the Gpio.prototype.write (line 200)
            to this

            Gpio.prototype.write = function (value, callback) {
              var writeBuffer = value === 1 ? ONE : ZERO;
              fs.write(this.valueFd, writeBuffer, 0, writeBuffer.length, 0, function (err, bytes, buf) {
                if (typeof callback === 'function') {
                  if (err) {
                    return callback(err);
                  }
            
                  callback(null, bytes, buf);
                }
              });
            };
            

            I have submitted issue 150 to the onoff module on github

                @Skorpionbird ok… on the issue I posted, the developer says latest onoff version should work too…

                4.1.1, hover-nodejs request 1.1.1 and got 1.2.0

                so another thing to try after this, is rename the node_modules/onoff folder to onoff-old
                then from MagicMirror folder do

                npm install onoff
                

                to get the latest

                and try running mirror again…

                there are some breaking changes in 4.1.0 and above, so its possible to cause more problems…
