Apps and feeds

FredM67 · 10 May 2020 21:06

Hi,
When I want to create a new app, for example My Solar, I get in the feeds list only the (real) feeds with PHPFINA. The other ones, PHPTIMESERIES and the virtual feeds are not shown in the combox list box !
Bug or feature?

Hi @FredM67,

I believe it’s because this engine list is limited to “5” by default:

github.com

emoncms/app/blob/5fc595aaa7de2c467acc43c70cc1cea7ba12650c/apps/OpenEnergyMonitor/mysolarpv/mysolarpv.php#L208


      
          $("body").css('background-color','#222');
          $(window).ready(function(){
              $("#footer").css('background-color','#181818');
              $("#footer").css('color','#999');
          });
          if (!sessionwrite) $(".openconfig").addClass('hide');
          
          // ----------------------------------------------------------------------
          // Configuration
          // ----------------------------------------------------------------------
          config.app = {
              "use":{"type":"feed", "autoname":"use", "engine":"5", "description":_("House or building use in watts")},
              "solar":{"type":"feed", "autoname":"solar", "engine":"5", "description":_("Solar pv generation in watts")},
              //"export":{"type":"feed", "autoname":"export", "engine":5, "description":"Exported solar in watts"},
              "use_kwh":{"optional":true, "type":"feed", "autoname":"use_kwh", "engine":5, "description":_("Cumulative use in kWh")},
              "solar_kwh":{"optional":true, "type":"feed", "autoname":"solar_kwh", "engine":5, "description":_("Cumulative solar generation in kWh")},
              "import_kwh":{"optional":true, "type":"feed", "autoname":"import_kwh", "engine":5, "description":_("Cumulative grid import in kWh")},
              "kw":{"type":"checkbox", "default":0, "name": "Show kW", "description":_("Display power as kW")}
              //"import_unitcost":{"type":"value", "default":0.1508, "name": "Import unit cost", "description":"Unit cost of imported grid electricity"}
          };
          config.name = "<?php echo $name; ?>";

You can see here in the config parser that you can set a comma-separated list:

github.com

emoncms/app/blob/5fc595aaa7de2c467acc43c70cc1cea7ba12650c/Lib/config.js#L385


      
              }
              
              return config.app;
          },
          
          engine_check: function(feed,conf)
          {
              if (typeof conf.engine === 'undefined') {
                  return true;
              }
              if (isNaN(conf.engine)) {
                  var engines = conf.engine.split(",");
                  if (engines.length>0) {
                      for (var z in engines) {
                          if (feed.engine==engines[z]) return true;
                      }
                  }
              } else {
                  if (feed.engine*1==conf.engine*1) return true;
              }
              return false;

Here’s the full list of possible engines:

github.com

emoncms/emoncms/blob/d8a9b177f5c608c6d830cd4277497500aad373cd/Lib/enum.php#L21


      
          }
          
          class DataType
          {
              const UNDEFINED = 0;
              const REALTIME = 1;
              const DAILY = 2;
              const HISTOGRAM = 3;
          }
          
          class Engine
          {
              const MYSQL = 0;
              const TIMESTORE = 1;     // Depreciated
              const PHPTIMESERIES = 2;
              const GRAPHITE = 3;      // Not included in core
              const PHPTIMESTORE = 4;  // Depreciated
              const PHPFINA = 5;
              const PHPFIWA = 6;
              const VIRTUALFEED = 7;   // Virtual feed, on demand post processing
              const MYSQLMEMORY = 8;   // Mysql with MEMORY tables on RAM. All data is lost on shutdown

So, for example, if you wanted PHPFINA and virtual then set this in the app’s config in the PHP:

“engine”:“5,7”

and you should see more feeds.

Hope that helps.
