Restarting a docker container on a remote machine from Home Assistant

I have a Raspberry Pi Zero W that runs a docker image of rtl_433, a popular data receiver for decoding data from popular sensors broadcasting on frequencies such as 433.92 Mhz or 915 MHz. For reasons unknown to me, thing stop working. I haven't been able to find out what causes the issue, but I did find that restarting the docker container seems to get things back on track. Setting up an automation that automatically reboots the container is not very elegant, but it works and ended seemingly endless troubleshooting.

The automation runs when Home Assistant does not see data from sensors that normally send an update every minute or so. It runs after 15 minutes of non-activity, and after 30 minutes of inactivity for good measure.

The automation informs my uptime tracking service and status page Uptime Kuma and then uses SSH to restart the docker container on the Pi.
