If you coming to Indonesia for work and your company is picking up the tab for housing and other necessities while paying you some Western salary then by all means, pay your domestic help big rupiah.
Or, when you arrive and get housing, talk to your neighbors about what they are paying. Keep it in that ball park and keep in mind, there is an annual bonus based on 1/12 of monthly wage times months worked.
Nannies are normally paid more than housekeepers and drivers more than nannies. Drivers are normally used around the house for maintenance and security when they are not driving. A driver with a car is quite a bit higher. If they speak English, they get more. When talking to people, know that Indonesian families pay the least, Chinese Indonesians next, and then foreigners with Westerners the highest. Indonesian and Chinese employers have a reputation of being very demanding to the point where it's sometimes considered abuse but people just look the other way until it is very evident.
Remember also that with live in, they have access to you 24/7 and know all your business and habits. Indonesians are also chatty with friends and family.
I would also recommend you stay far away from any so called domestic worker agents. It's a racket that only benefits mainly the agent, then maybe a worker but never the employer who is paying them.
