Ok, I was afraid of that. So i need to make logic that only reads topic once, and then sorts out the different values I'm looking for.

So I made a function to look up certain names in the table, is there any way to have the mqtt_to_object run without a GA attached? It will only run the first grp.write:

Code:

function conv_shellyTemp(payload)   local data = require('json').pdecode(payload)        if type(data) == 'table' then                function tableHasKey(table, prefix)                         for key, _ in pairs(table) do                       --log(key)                         if string.match(key, prefix) then                         return true                         end                         end                         return false                         end          if tableHasKey(data["params"],"temperature") then                    grp.write('33/1/8', data["params"]["temperature:100"]["tC"])                 grp.write('33/1/10', data["params"]["temperature:101"]["tC"])        elseif             tableHasKey(data["params"],"switch") then                    grp.write('33/1/9', data["params"]["switch:0"]["output"])           else         log("no data")         end     end   end
