Number of "Pulses" Detection

[admin]

Resident script with sleep time set to 0. You only need to edit the config table. You will need to restart the script via disable/enable after each config edit. In the config table each key is a group address which sends 1 on button press and 0 on button release. Value for each key is another table with the button configuration. This way you only need a single script for all buttons with multiple press functionality.

Code:

if not client then
  config = {
    ['0/0/1'] = {
      timeout = 0.5,
      longpress = 1,
      press = function(ptype, count)
        local light1 = '1/1/1'
        local light2 = '1/1/2'

        if ptype == 'short' then
          if count == 1 then
            grp.write(light1, not grp.getvalue(light1))
          else
            grp.write(light2, not grp.getvalue(light2))
          end
        else
          grp.write(light1, false)
          grp.write(light2, false)
        end
      end
    },
    ['1/1/3'] = {
      timeout = 0.5,
      press = function(ptype, count)
        log('press 1/1/3', ptype, count)
      end
    }
  }

  function groupwrite(event)
    local cfg = config[ event.dst ]

    if cfg then
      cfg.pressed = tonumber(event.datahex, 16) ~= 0

      if cfg.pressed then
        cfg.timer = 0
        cfg.count = (cfg.count or 0) + 1
      end
    end
  end

  function press(cfg, ptype, count)
    if type(cfg.press) == 'function' then
      cfg.press(ptype, count)
    end

    cfg.pressed = false
    cfg.timer = nil
    cfg.count = 0
  end

  client = require('localbus').new(0.1)
  client:sethandler('groupwrite', groupwrite)
end

ts, tu = os.microtime()
client:loop(0.2)
diff = math.max(0, os.udifftime(ts, tu))

for addr, cfg in pairs(config) do
  if cfg.timer then
    cfg.timer = cfg.timer + diff

    if cfg.pressed then
      if cfg.longpress and cfg.timer >= cfg.longpress then
        press(cfg, 'long')
      end
    elseif cfg.timer >= (cfg.timeout or 1) then
      press(cfg, 'short', cfg.count)
    end
  end
end
