Alarm page demo using javascript and tag - fleeceable - 29.04.2024

Hello!

I haven't found any slim alarm notification example so I created one (using forum magic search button and all kind of code examples). I bet there is quite many good programmers who maybe want to add some additional features. Would be nice to see these in this thread...

About page. It gonna check alarms by tags and shows in two separate table. One is active alarm table and another is event table. It's possible to delete all past events as well. 
Integration should take less than few minutes.
Alarm page date and time is actual alarm variable update time. Event date and time is time when system checked event variable (not actual alarm time).

Common functions:
Code:
function eventlog(text)
  local max = 30                             -- MAX NUMBER OF ENTRIES
  text = os.date('%d/%m/%Y %T ') .. text
  storage.exec('lpush', 'eventlog', text)
  storage.exec('ltrim', 'eventlog', 0, max - 1)
end

Resident script 3s:

1. Define group address base
2. Add tag-s what to check periodically
3. On first run change first three lines to true. Later change back to false
4. Activate script


Code:
create_eventlog_file = false                 --Execute on first run to create lp file
create_all_log_file = false                --Execute on first run to create lp file
create_group_addresses = false                --Execute on first run to create group addresses

group_address_base = '51/1/'                    --System generates two group addresses. Make sure that addresses are free (x/x/1 and x/x/2).
alarm_tags = {'SV1','SV2','SV3','EMAIL','HEATING'}        --These are alarm tags what is gonna checked constantly

-------------------------------------------------------
data1 = {
   type = 'event',
   name = 'ALARM PAGE - Update frontend',
   active = 1,
   params = group_address_base .. '1',
   subparams = 0,
   script = [[val = event.getvalue()
      if val then 
          grp.checkupdate("]] .. group_address_base .. [[1", 0)
        end]],
   category = '',
   description = 'Automatically generated',
}
data2 = {
   type = 'event',
   name = 'ALARM PAGE - Delete eventlog',
   active = 1,
   params = group_address_base .. '2',
   subparams = 0,
   script = [[val = event.getvalue()
      if val then
  storage.delete('eventlog')
  grp.update(']]..group_address_base .. [[2',0)
  grp.update(']]..group_address_base .. [[1',1)
end]],
   category = '',
   description = 'Automatically generated',
}

function create_scripts(data)
  exists = script.get(data.name)
  if not exists then
     db:insert('scripting', data)
     data.id = db:getlastautoid()
     script.save(data, true)
     script.reloadsingle(data)
  end
end

function createga(groupaddress,datatype2,name2)
  exist = grp.alias(groupaddress)
  if exist == nil then
    address = grp.create({
    datatype = datatype2,
    address = groupaddress,
    name = name2,
    comment = 'Automatically created object',
    units = '',
    tags = { },
    })
  end
end

if create_group_addresses then
    createga(group_address_base .. 1,dt.bool,'ALARM PAGE - Update frontend')
  createga(group_address_base .. 2,dt.bool,'ALARM PAGE - Delete eventlog')
  os.sleep(0.5)
  create_scripts(data1)
  create_scripts(data2)
end

function file_exists(name)
  local f = io.open(name, "r")
  return f ~= nil and io.close(f)
end

if create_eventlog_file then
    fil_name = '/www/user/eventlog.lp'
    if file_exists(fil_name) == false then
    dst = fil_name
    io.writefile(dst, [[<?
    require('apps')
    items = storage.exec('lrange', 'eventlog', 0, 999)
    text = table.concat(items, '\r\n')
    print(text)
    ?>]])
  end
end

if create_all_log_file then
    fil_name = '/www/user/all_alarms.lp'
    if file_exists(fil_name) == false then
    dst = fil_name
    io.writefile(dst, [[<?

      index = index + 1
      if events[i].value == true then
        if old_val ~= nil then
          if old_val[i].sent == false then

            update_storage = true
            update_table = true
          end
        end

            eventlog('0 ' .. events[i].tagcache .. ' ' .. events[i].name ) -- 0 means ok
            update_storage = true
            update_table = true
          end
        end
      end
    end
    if update_storage then

    end 
  end
  if update_table then
      storage.set('ALL_ALARMS',all_alarms)
    os.sleep(0.5)
    grp.update(group_address_base .. '1', 1)
  end
end

check_events(alarm_tags)

Custom Javascript:

1. Define your plan ID where alarm and event table gonna be placed
2. Edit updateTableGA address. 
Do that on both scripts...

Email notification part is running on another script right now but maybe I'm gonna integrate into this script in future.
