snooze VS OpenMQTTGateway

/u/Niki_Roo is right - better to dispense with the sleep and loop by making it a cron job. (or, for a self-contained alternative tailored to Void, snooze)

There are different things you can do, yes either cron jobs or there is something like snooze written and maintained by a void maintainer which fits into the runit/supervision design. I guess you could say its a similiar user expieriece as timer units if you don't want to run cron jobs. You basically create a service with the timing specifications and snooze will wait and then execute into the command when its time to run, then it will just exit and runit will start the service again and it will continue to sleep until the next scheduled run. There are other similar programs like at(1) and all the common cron implementations are available in the repository, void does not come with a default cron daemon, so its completely up to you.

I'll rather use something like snooze to create runit services for each timed job, which integrates well into supervision/runit and I can use runits logging mechanism. I can use sv to send signals to a running job or to the snooze process to immediately start the job with SIGALRM. I will have features like time files, which allow me to do things like "run the job every 5 minutes, after the job finished" or "once a day" while remembering state between reboots.

Which one you choose will depend on what you need. dcron is the simplest implementation, while cronie and fcron both have more advanced features. You may also be interested in checking out snooze.

Basically it boils down to using a process supervisor called runit and a fancy big brother to the unix sleep command called snooze.

Loaded with OpenMQTTGateway and relying on an ESP32, it brings exceptional range with its external antenna, ensuring your BLE devices stay connected through ethernet or WiFi.

If your device is on the list of devices supported by Theengs Decoder, you can fetch its readings with OpenMQTTGateway (on ESP32) or Theengs Gateway (on a Raspberry Pi or other computer).

If you can find a 433Mhz version of this, you could use OpenMQTTGateway with a Lora board and use it to connect to multiple 433 style items. In fact, it may be able to handle this exact one with the 868Mhz Lora module directly. I'd check with the project forums first though.

And the package https://github.com/1technophile/OpenMQTTGateway should have everything setup as a straight forward package to get started
