Tell me your other requirements and the budget. If you want something in BMS level with industrial communications it will cost more. Ex products would be Honeywell, Johnson controls etc. If you want a project/prototype cost will be much lesser. Can use Arduino, raspberry etc.
PM if you need any help.
