Sending telemetric data to DCM (or any other backend) could provide better traceability of random device reboots etc.
If desired, i can make a backend that can retrieve that data and generate graphs for each device and parameter.

int sendTelemetricData (void)
{
    // Device name
    NSString *deviceName = [[UIDevice currentDevice] name];
	
    // Battery percentage
    UIDevice *device = [UIDevice currentDevice];
    device.batteryMonitoringEnabled = YES;
    float batteryLevel = [device batteryLevel] * 100.0f;
    
    // CPU temperature
    int mib[2];
    mib[0] = CTL_HW;
    mib[1] = HW_CPU_TEMPERATURE;
    int64_t temperature;
    size_t length = sizeof(temperature);
    sysctl(mib, 2, &temperature, &length, NULL, 0);
    float cpuTemp = temperature / 100.0f;
    
    // Init
    CURL *curl;
    CURLcode res;
    curl_global_init(CURL_GLOBAL_ALL);
    curl = curl_easy_init();
    
    if (curl)
	{
        curl_easy_setopt(curl, CURLOPT_URL, "http://YOUR_DCM_URL");
        curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "device_name=%f&battery_percentage=%f&cpu_temperature=%f", [deviceName UTF8String], batteryLevel, cpuTemp);
        
        res = curl_easy_perform(curl);
        if (res != CURLE_OK) {
            fprintf(stderr, "dmon: curl_easy_perform() failed: %s\n", curl_easy_strerror(res));
        }
        
        curl_easy_cleanup(curl);
    }
    
    curl_global_cleanup();
    return 0;
}

Right now if the webserver doesn't have a valid path curl is still exiting with return code 0. Need to add some better error handling. Also make sure we don't save an empty file to disk.

I'd appreciate it if dmon also constantly reset the display brightness to 0. Some devices keep bugging me with that.

#import <UIKit/UIKit.h>

int dimDisplayBrightness (void)
{
    @autoreleasepool
    {
        UIScreen *mainScreen = [UIScreen mainScreen];
        mainScreen.brightness = 0.0f;
    }
    return 0;
}

Bug

The following method of detecting if Pokemon Go is running is flawed

Even with the game closed the process can still be running. Didn't catch this edge case initially.

root# ps aux | grep -i "PokmonGO.app/PokmonGO" | grep -v grep
mobile         23398   0.0  0.2 408075872   3888   ??  Ss   11:45PM   0:00.50 /var/containers/Bundle/Application/42E6155C-F220-4682-9CBC-25ECAB5BD2DC/PokmonGO.app/PokmonGO

Potential fix

Initially I wanted to do game detection via the proper Apple API. But no matter what I try I always get null as the output. Tried a few different varaiations in the following file to get [(SpringBoard *)UIApplication.sharedApplication _accessibilityFrontMostApplication]; to work but never got anything usable.

Sometimes PoGo stops working even though it's opened and the frontmost app, so a better approach would be to check if PoGo is actually doing something. Those functions check the last log time of GC and then checks if it's more than 5 minutes in the past. We can further tweak that time frame in the future.

#include <asl.h>
#include <time.h>

int pogo_work_state(time_t log_time)
{
    time_t current_time = time(NULL);
    return (difftime(current_time, log_time) > 300);
}

time_t get_last_log_time()
{
    aslclient client = asl_open(NULL, "com.gocheats.jb", 0);
    aslmsg query = asl_new(ASL_TYPE_QUERY);
    asl_set_query(query, ASL_KEY_SENDER, "com.gocheats.jb", ASL_QUERY_OP_EQUAL);
    aslresponse response = asl_search(client, query);
    aslmsg msg;

    time_t last_time = 0;
    while ((msg = aslresponse_next(response)) != NULL)
    {
        const char *time_str = asl_get(msg, ASL_KEY_TIME);
        time_t time_val = (time_t)strtoll(time_str, NULL, 10);
        if (time_val > last_time)
        {
            last_time = time_val;
        }
    }

    aslresponse_free(response);
    asl_free(query);
    asl_close(client);

    return last_time;
}

Just flat forgot. The LaunchD unload/reload is the only piece I'm a little concerned about. If dmon is subbing out to popen & the daemon is unloaded I'm not sure if the rest of the postinstall script will run.

Since GC already requires DCM it might make sense to have it host the packages.

If someone wants to work on this the version.txt file should likely stay the same format? Just have nodejs build the config map on get request. Also I'd like to make it optional so users can use basic web server or DCM.

I am not scheduled work for this. Resource limited at the moment but will accept a PR.

Bug

In order for substitute to properly install we need to apt update & apt upgrade on the phone. Ideally we want this to occur silently but unsure if there are any supported CLI flags that will do this.

Potential fix

If we can't get the following to work we should link the two correct .debs in the readme. The downside it they can't be easily updated via apt update.
