On dss devices battery is very much a function of radio time and # of messages. Well and battery size of course.
My mailbox one only sends 3 messages a day (heartbeat plus mailbox being opened 2x).
My fridge updates hourly.
Most of the off the shelf LoRa sensors have pretty big batteries, so life is always pretty long.
My fridge one will die sooner due to temp, but should be good for 2-3 years right now.
My mailbox one - if it stays at the same speed/radio time - should make 5+ years.
2400 mAh battery in both, though. If they were 320 mAh coin sized, well obviously life would be much less!
I am curious how long my pool pump pressure sensor will last. it updates every 5 minutes. The battery life calc spreadsheet and my measured battery data aren't agreeing. The battery data looks better than the calc spreadsheet would have led me to believe.
Right now LoRaWAN --> MQTT --> Node-RED. Would be very somewhat easy to write an integration to go LoRaWAN --> Hubitat though through Maler API. At least with Chirpstack, which is what I use for the lora side. Or could do lora --> mqtt --> hubitat today with Kevin's MQTT app.
Will obviously be MUCH easier to do zwave lr once available as we can just do that straight in the Hubitat C-7 hub with no man-in-the-middle. If zwave.me comes out with a Z-Uno MODULE on the 700 series chip I may even covert my stuff from LoRa back to zwave lr so I can get rid of the lora hub, but we'll see. If they only do the Z-Uno 2 (not the 'module' version) it would probably be too expensive (and big) to convert the devices from lora to zwave lr.
Although I have 30 lorawan sensors on their way from china, too... The more pre-made lora sensors I get, the less likely I am to abandon it. lol. The ones I make myself could go either way though.
Oh, and I actually calced my battery wrong now that I looked (wrong radio wake time). I should get many years out of either. Mailbox actually calcs out at 9 years, but I doubt that.
