12/13/2023 0 Comments Istat menus sensors![]() ![]() Installed the new version, which is 6.61, now the sensors are listed. In addition to providing you extra sensors and extensive stats, iStat Menus 6 also allows you to change the look of your menu bar icons, dropdowns, and graphs. total system power draw, just by replacing the queried key. The version I had installed was 6.6, sensors were not working and checking for updates told me I had the current version. IOConnectCallStructMethod(ioc, 2, &req, sizeof(req), &resp, &sz) īased on Luyer's amazing answer (reading charger voltage and current from SMC) and a list of SMC keys from here: we can read many other values, like the requested "current wattage" a.k.a. IOServiceOpen(svc, mach_task_self(), 0, &ioc) By default, iStat Menus embeds five displays in your Mac’s Menubar: CPU, Memory, Solid State Drive, Network, and Sensors. IOServiceGetMatchingServices(mp, d, &it) Build with: gcc -o psudata -framework IOKit It all depends on what you really want to do with the data other than learn how the hardware works and have some cool graphs. Then you could correlate these with CPU usage monitoring that is trivial over time using top and be able to add things up. 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. No thanks I don’t think I’m paying a subscription for iStat Menus there were some added premium features, like weather and such, but I didn’t opt in to those and it hasn’t been an issue. I suppose some PHD thesis might be done on integrating the fan speed and various temperature sensors to calculate an expected power consumption. TSE said: I would love iStat Menu vs TG Pro, except for it costs 10 every 6 months vs. 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. After re-installing all of my software I Realized that. ![]() I since returned that unit for the new 16' MBP. No metered sensors are present in the power supply. 1 Hello, I had the MBP 15' and the sensors all showed within the application properly. 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: 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. Daniel Galasko's excellent post on Medium about background timers in Swift was followed to include the class "RepeatingTimer".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?. ![]() The class, "Background_Timer", should conform to the ObservableObject protocol for interaction with the UI. Create a new Swift file within the macos-temperature-monitor group and call it "Background_Timer.swift".The steps followed for its implementation were: Ī background timer was used to request the CPU temperature at regular intervals. I am following Sébastien Lavoie's example and applying the GNU General Public License v2.0 to this project because it uses devnull's smc library. The fuzzer at is very interesting, and I may use it in the future to dynamically populate a list of available sensors, but for now I am content to use the average of two SMC keys (TC0E and TC0F) that report the CPU die temperature as reported by a superuser forum post. The SMC can be used to retrieve various sensor readings and set fan speeds. ![]()
