Hi good day,

Denisse, to get all unit groups You have access to - just try to use:
wialon.core.Session.getInstance().getItems("avl_unit_group")
or
wialon.core.Session.getInstance().searchItems({itemsType:"avl_unit_group",propName:"",propValueMask:"",sortType:""}, 1, 0xFFFFFFFF, 0, 0xFFFFFFFF, function() {console.log(arguments);});
if You want to get unit groups of some specific account use such request:
wialon.core.Session.getInstance().searchItems({itemsType:"avl_unit_group",propName:"sys_billing_account_guid",propValueMask:"X",sortType:""}, 1, 0xFFFFFFFF, 0, 0xFFFFFFFF, function() {console.log(arguments);});
replace X with account id You are interested in
Thank you very much for de answer.
And one questions more, If I get theunit group also I get units that belong to the selected group?
Denisse, to get units of each group that belong to some account You can do the following:
wialon.core.Session.getInstance().searchItems({itemsType:"avl_unit_group",propName:"sys_billing_account_guid",propValueMask:"X",sortType:""}, 1, 0xFFFFFFFF, 0, 0xFFFFFFFF, function(code, data) {
if (code || !data || !data.items)
return;
var units = [];
for (var i = 0; i < data.items.length; i++) {
var group = data.items[i];
var groupUnits = group.getUnits();
for (var j = 0; j < groupUnits.length; j++) {
units.push(groupUnits[j]);
}
}
console.log(units);
if (units.length)
wialon.core.Session.getInstance().searchItems({itemsType:"avl_unit",propName:"sys_id",propValueMask:units.join(","),sortType:""}, 1, 0xFFFFFFFF, 0, 0xFFFFFFFF, function() {console.log(arguments);});
});
Thank you very much for the answer.

Hi!
A question, the reports, can I execute for unit group with same library avl_unit_group?
Suggest please?
Denisse, try to modify this example for unit groups instead of units:
https://sdk.wialon.com/playground/demo/execute_report
Thank you deal
Hi deal good day,
The detail of my query is that I am getting the units that belong to a group but wanting to get their position or names I can not. I put the code that modifies according to Playground. Some suggest or idea please, I will be very important, thanks

Denisse, you don't get units because only unit_groups were added to session.
Just add units to updateDataFlags:
[{type: "type", data: "avl_unit_group", flags: flags, mode: 0}, {type: "type", data: "avl_unit", flags: flags, mode: 0}]
Add lastPosition data flag: wialon.item.Unit.dataFlag.lastPosition
Also change code of getting units' positions:
msg(unidades.length);
for(var j=0;j<inidades.length;j++){
var u = wialon.core.Session.getInstance().getItem(inidades[j]);
msg(u.getPosition()); //THIS PROBLEM NO INFORMATION
}
Good day deal
Thank you for this information, I am grateful.
Hi,
If I have a list of groups, how do I get the list of selected group units?
mshamsan hello,
You can try to use search items by properties request. This request allows to get internal IDs of the items and other properties. You can use it to get all available unit groups names and IDs and array of units' IDs included in each group.
Example of the request: https://hst-api.wialon.com/wialon/ajax.html?svc=core/search_items¶ms={"spec":{"itemsType":"avl_unit_group","propName":"sys_name","propValueMask":"*","sortType":"sys_name"},"force":1,"flags":1,"from":0,"to":0}&sid=ACTIVE_SID
The units IDs will be available in the "u" parameter array.
Then you can use IDs of the units t search specific unit details with search item by ID request.
