Probably bug in dynamic notifications

Mon, 05 Jan 2026 17:57:16 +0000

I use the iOS app „cache notifier“ which works quite nice. Now I am on holiday and I get notifications from home.

It seems like PGC inserts my home coordinates. cache notifier shows the correct coordinates. If I the. turn off cache notifier and turn it on again, PGC shows the correct coordinates.

New Cache notifier: County selecteion not showing counties if region selected

Fri, 05 Sep 2025 10:55:21 +0000

When creating a new cache notifier, the counties wont show if a region is selected. They do get loaded, but are not shown in the dropdown.

If no region is selected the counties are shown and selectable.

Better Documentation of Dynamic Location Update URL

Mon, 18 Aug 2025 07:31:03 +0000

The New Cache Notifiers page has documentation for setting up GPS Logger for Android, but it does not have a generic documentation of the parameters supported by the https://project-gc.com/api/UserLocation/Update/ API.

A documentation would be nice, especially for parameters that are non-obvious, e.g. like this:

# Help: Dynamic Notifiers

You can dynamically update some settings of a notifier by using the URL https://project-gc.com/api/UserLocation/Update/ with parameters. Supported parameters are:

protocol=1 - the update protocol to use, this must always be 1
uid=<USER-ID> - your user ID. Use the user id from your settings page.
token=<TOKEN> - the access token to Project GC. Use the token from your settings page. Keep in mind that the token should be kept as safe as a password.
nid=<NOTIFIER-ID> - the ID of the notifier. You can see a notifier's ID if you edit it
ts=<timestamp> - the timestamp of your update, in ISO-format, e.g. 2025-01-31T14:35:59+0100. Updates that have a timestamp that is older than the most recent update are ignored (?)
latitude=<latitude> - the latitude of the dynamic location, using decimal degrees, such as 12.34567
longitude=<longitude> - the latitude of the dynamic location, using decimal degrees, such as 56.78901
acc=<accuracy> - the accuracy of your latitude/longitude measurement in meters. (why would this be relevant?)
enable=1 - if you add this parameter and the notifier is currently disabled, the update will enable it

To update a notifier, add the parameters to the URL after a question mark, separate them via & signs, for example like this: https://project-gc.com/api/UserLocation/Update/?protocol=1&uid=<USER-ID>&latitude=<latitude>&longitude=<longitude>&ts=<timestamp>&token=<TOKEN>&nid=<NOTIFIER-ID>

New cache notifier dynamic location updater

Mon, 10 Jun 2024 20:31:04 +0000

This is not a question, but rather a solution created by me to ease the process of updating dynamic location for new cache notifiers.

I found the configuration of GPS logger overwhelming for what it's supposed to do regarding the new cache notifiers at Project-GC.

I have created a simple yet useful webapp that imitate the request that GPS logger makes to update the new cache notifier with dynamic location. It does not use any data on server side. It just composes a URL that GPS logger sends on location updates and performs it on behalf of the user. It remembers the values in user's browser.

One can choose location from the map or use the device's GPS to update the notifier location. It should work on all mobile devices.

If you want, you can check it out working here: https://fracz.github.io/pgc-location-updater/ and the source code is available here: https://github.com/fracz/pgc-location-updater/blob/main/index.html

Happy hunting!

"Lowst" Not Lost and Found New Cache Notifier

Mon, 02 Aug 2021 05:18:46 +0000

New Cache Notifier for Community Celebration Event titles the email with "Lowst" and Found. The correct spelling would be "Lost."

The cache type details in the email has the correct spelling

Potentially the title and cache type info could be changed to reflect the rename to "Community Celebration Event"

Feature request: Attributes as filter in New cache notifiers

Thu, 11 Feb 2021 12:36:48 +0000

I think an option to set up New cache notifiers with attributes as filters would be a nice addition. If it is possible to add of course.

Some examples of the uses I can see for this would be:

Setting up notifiers for your local area with caches with the "field puzzle" attribute as instant notifiers and having a "all mystery caches" as a daily digest.

Setting up a daily digest for challenge caches for a region or country even if you don't want notifications about every mystery cache for the same area.

Daily digest of all caches in a country/region with for example the attribute "abandoned structure" (or maybe "scuba gear required", "abandoned mine", "climbing gear required" or whatever your preferred type of adventure is) to see if anything interesting pops up for your next road trip.

And so on, I'm sure there are many ways to use this. :)

Maybe a "not allowed" option would also be useful? Here I'm mainly thinking about solving the problem where I know some people become frustrated with power trails maxing out the 30 day limit of their notifications, so I'm thinking a user in a powertrail rich area could add a "not allowed" to the power trail attribute for all their notifications and would get their normal notifications for all caches that does not have the power trail attribute and no notifications for caches with the power trail attribute. But it could of course also be used for things like "T5 caches without the attribute boat required" and other things.

Feature Request: Add New-Cache-Notifier results on a predetermined list in the virtual GPS

Tue, 01 Sep 2020 14:13:22 +0000

I have a long List in the New-Cache-Notifier and I am getting emails for every new Cache of some Owners. It would be nice if the results would not only be sent by email but could also be saved on a previously defined list in the virtual GPS.

New cache notifiers - First log URL incorrect

Sat, 12 Oct 2019 22:57:37 +0000

The New cache notifiers send out a log when a new cache gets its first found it log. I have noticed recently that the URL for the cache in that message is incorrect and listed as https://coord.info/GLZZZZZZ

The URL previously reflected the cache that corresponded with the actual cache.

I've provided some example screenshots:

Looking at past emails the URL was correct on Oct 6th but all notifications since Oct 8th have listed the URL as https://coord.info/GLZZZZZZ

Is it possible to create a notifier for new challenge caches?

Wed, 10 Oct 2018 10:25:58 +0000

I have some GC cache notifiers and some PGC event notifiers and I wanted to create a PGC cache notifier for new challenges.

But is it possible to create a notifier based on the partial name "challenge" or on the "has checker" attribute?

no daily notifiers on september 17 2018

Mon, 17 Sep 2018 10:41:32 +0000

None of my daily notifies arrived in my inbox on September 17th. A typical day has several hundred new caches as I watch about 10 countries and a similar number of US states. This seems more likely a glitch than a reality.

I cannot figure out if this means they did not run on the server or if there is a problem with the delivery of e-mail.

https://project-gc.com/User/NewCacheNotifiers does say 7/100 ran on my daily limit but if the same process updates this as send's the e-mails, it may be the same results held over from the 16th.

Did anyone else have this problem?

New Cache Notifier doesn't work

Thu, 06 Sep 2018 20:58:57 +0000

I followed your advice to create a list of new caches from a certain owner but it doesn't work. Of none of the caches that were published after 09/01/18 (that's the date when I created the notifier) I was informed by mail.

But: all the caches I talk about are hidden already in June or July 2018. Could that be the reason why the notifier skript can't identify them as "new"?

Feature Request: I like to receive notifications of new caches placed by selected owners.

Mon, 27 Aug 2018 14:03:58 +0000

I regularly find great caches of creative owners outside of my homezone. But then I often don't notice when they create new caches later. I'd like to be notified of new caches from these previously selected owners.

Inconsistent results between multiple new cache notifiers (digest)

Thu, 14 Jun 2018 10:11:47 +0000

So lets start off with the new cache notifiers are great. The digest mode is what I use.

So why this post? I have two notifiers set up one for Texas, and one for "Texas, Oklahoma, Arkansas, and Louisianna".. My expectation is that the Texas one would always have fewer than the bigger one. And than anything in the Texas one would show up in the bigger one. The bigger land area has one has Texas caches listed, but the two never seem to have the same same cache. It appears either in one or the other.

Is this the expected behavior? Are the few Texas ones I see coming through the results that the emails are generated at different times?

My plan is to disable the Texas one and see what happens. My concern is that I lose notifications.
