I used to use the TPL5010 and posted a fair bit on this topic a while back.

Boron / Xenon / Argon Carrier for Outdoor Applications

@shanevanj, Let me take a look at that one. I have already slapped the DS1339 with a supercap on the board. Take a look at this part (I have a library that works as well). I will do the same with the PCF8523 [44%20PM] [56%20PM] Thanks, Chip

However, I moved away from the TPL5010 to and ATTINY based approach for one main reason: while you can configure the TPL5010 for a 1 hour cycle, you cannot "reset" or "restart" that period. So, if you wanted to align the 60 minutes to the clock, it will not work.

Project Share - Build a better external watchdog to improve device reliability

I have been using the Texas Instruments TPL5010 in my remote outdoor projects and it has served me well by saving me trips reset errant devices. However, as my projects have matured and with the capabilities of the new Generation 3 devices, I found the TPL5010 lacking. There are three things the TPL5010 cannot do: Allow my to dynamically set the interrupt interval Reset the interval when the watchdog is “petted”. - @TI, this one is a serious miss! Support more robust “petting” to preclude t…

Then, I moved to the AB1805 which is the current path.

As for the cellular connection, there is no issue with disconnecting and reconnecting every hour. However, you want to make sure you disconnect from Particle and turn off the cellular radio before turning off power to the Boron.

Hope this helps,
