Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Webhooks suck, but here are alternatives
In fact, your platform (https://healthchecks.io/) is a prime example of where running customer wasm would be really excellent.
Instead of sending webhooks out to customer configured URLs, you could run a Wasm environment to execute customer code. Off hand, a good use case here is to do further inspection of the event before it gets sent off to some other system - maybe there are cases where you send false-positives and needlessly trigger external system alerts. The customer Wasm could do more introspection on the healthcheck event and make a more informed decision about how to proceed.

What do you use for external monitoring?
i use healthchecks.io and have been very happy
with Uptime Kuma and healthchecks.io, you can do everything. Uptime Kuma to monitor "services" (web server, database), and healthchecks to monitor punctual jobs (backup jobs, etc)

Ask HN: How do you monitor your systemd services?
If you are ok with a Saas and if it's just scheduled jobs that you are monitoring, there are a number of monitoring tools where you tell when job completes (with a http request) and a missing ping (after a grace period) means that it failed.
I think https://deadmanssnitch.com/ may have been the original service for this.
https://healthchecks.io/ has a fairly generous free tier that I use now.
There are others that do the same thing Sentry, Uptime Robot, ...

Show HN: Peeng – like Pingdom, but the other way around and simpler
A service in a very similar vein is https://healthchecks.io/ - which also provides a nice perspective on how low-effort the setup for a service with a substantial amount of users can be. https://news.ycombinator.com/item?id=31488910
The blog also contains a bunch of useful information and guides around the topic, including various unusual configurations (arduino/esp8266) as well as information on self-hosting.

Detecting and alerting for power failures
i use https://healthchecks.io/ and highly recommend it.
You can use a service like https://healthchecks.io/ for example. There is an article describing the idea here: https://www.signl4.com/blog/monitoring-still-alive-heartbeat-check/.

Which tiny ESP with battery management to measure voltages up to 5V?
Have you seen b-parasite? There is a sample that uses zigbee, and somewhere in the issues someone had used an NRF528x chip that had an attachable antennae, which may help your BLE connection issues.

A Bluetooth Low Energy (BLE) soil moisture sensor
I can see how your prototype defends against corrosion, not so much this b-parasite toy.
What I don't see anyone talking about is the impact of dielectric moisture absorption[1], which is typically around 0.3-0.5% for cheaper FR-4 on the market, on corrosion, let alone how this product intends to maintain sensor calibration over time.
I'd expect to see external corrosion impact at the solder joints first, especially around the battery terminals, but corrosion creep may happen alot sooner than that: vias in the b-parasite prototype are clearly tented[2], but that masking is superficial and won't protect against hygroscopic exposure from the inside; being open source certainly doesn't preclude hobbyists from making even worse material decisions.

It works with Home Assustant, as discussed in the repo:

b-parasite sensors ready to final assemble
b-parasite is an open source Bluetooth Low Energy (BLE) soil moisture and ambient temperature/humidity/light sensor.
Never mind, I found more info on this: https://github.com/rbaron/b-parasite/issues/33
