Please note that we need to ensure new providers have the data required, allow commercial use, and meet our technical requirements. We will consider adding other sources in the future. iStat Menus does not use any kind of auto-renewal, and there is no commitment to buying in the future. No subscriptions #Īll of our data packs are one-off purchases. If you purchase a data pack with a different interval as you’re currently using, it will replace the amount of time. If you purchase a data pack with the same interval as you’re currently using, it will extend the amount of time. Data packs can be purchased from within iStat Menus, under the Weather tab. The data packs start from USD$2.49 (plus local taxes) for 12 months.
Istat menus sensors free#
We do provide some free weather data as part of purchase price though (typically many months).Īfter that period, you’ll need to purchase one of the data packs from within iStat Menus to continue viewing weather information. Doing so would have meant increasing the price of iStat Menus to cover the average usage. This makes it very difficult to include an infinite amount of weather data as part of the main app price. The services we use charge us ongoing fees to provide data, based on usage. We want to provide the best weather data we can. There are some subtle differences across the different sources, and which features they support. All the providers are premium weather services with high quality data. Please note that WillyWeather is a service that provides BoM data for Australia. We set a sensible default, based on your location. You can choose the provider you’d like from within iStat Menus. IStat Menus uses The Weather Channel, Dark Sky, AccuWeather, and WillyWeather for weather data.

Then you could correlate these with CPU usage monitoring that is trivial over time using top and be able to add things up.
Istat menus sensors mac#
You could rent or buy a unit that measures the power through the outlet and then run some test to see how much power the mac takes over an hour in certain conditions. Decent home energy counters are between $150 and $300 w In reality since that data isn't exposed or recorded, you might have to measure externally. It's possible to get a calculation and with some calibration, it might even be pretty accurate. I suppose some PHD thesis might be done on integrating the fan speed and various temperature sensors to calculate an expected power consumption. The logic board measures temperature in several places to control the blowers and the CPU monitors temp to reduce clock rate when it becomes warmer than the blowers can cool it.
No metered sensors are present in the power supply.
How can I get my hands on that data programmatically? It does state "sensors", but they might be calculated as commented. Just to inform: the aforementioned iStat Menus 3 lists the following power related sensors:
Istat menus sensors software#
So the meters are there, but how I could access them programmatically?īounty! Will be given for solid command-line sensor reading solution or for recommending exceptionally good 3 rd party software (like one with statistical and historical data tools at minimum). I know, it probably is just a wet dream, but a watt meter on board would be ideal for the computer to shout: "Look how eco-friendly I am using just these Kerri Shotts' suggested iStat Menus 3 do get the wattage readings from some sensor, along with volt and amp stats. The meta–question in here was that is there any sensors/readers already on the PSU, that would work kind of like the way "kill-a-watt" works. I'm most interested in command-line/applescript based solutions for more convenient logging & stats, but I'm open for alternatives.īoth bmike's & michaelmichael's) answers are undoubtedly correct.
Is there a way to retrieve the current watt usage info on OS X Snow Leopard? I'm using mid-2010 iMac, so I'm not looking for just battery-related apps.ĭoes OS X even monitor power usage? Do I need to use an external reader between the power cord and the outlet?
