You can try this way, log your object for a day and then use this script, change logaddress and pastTime as needed. 

Code:

logaddress = '32/1/3'
pastTime   = 60*60*1  --in seconds


addr = grp.find(logaddress)

time= os.time() - pastTime

objects = db:getall('SELECT dataraw, logtime, datahex FROM objectlog WHERE address =' .. addr.id .. ' AND logtime >'.. time )

local result, value = 0,0

    for _, objvalue in ipairs(objects) do
  value = busdatatype.decode(objvalue.datahex, addr.datatype)
 
        result = math.max(result, value)
   end
log(result) --max



    for _, objvalue in ipairs(objects) do
  value = busdatatype.decode(objvalue.datahex, addr.datatype)
      result = math.min(result, value)
   end
log(result) --min
