Thanks for the reply.  I was quoting figures reported on my VZ wireless mifi device account for three sensors, which seems a fair amount lower than what was reported there.

Another point of difference – the response said cumulative results should be maintained even if the internet connection goes down, while what I saw on my initial reading after the system was set up was that the cumulative data did not seem to be reported.   I’ll have another opportunity to check that shortly, with the batteries on the MIFI device and backup battery now dead after 5 days running, next time I can get in to power that back up.

THanks for the reply.

I’m looking at IOT cellular data plans.

I’ve got 3 phase power, duplex so six sensors, and I think that will wind up with about 50 MB/monthly, probably about 10mb  more, based on roughly 1mb/day with three sensors installed.

Digi-Circle has plans that on CAT-M service run $6/month for 50mb, or $9 for 100mb.  https://www.digikey.com/en/resources/iot-resource-center/iot-cellular-data-plans.  This on Verizon network, required as the only provider that reaches our septic tank without a tower antenna.

There are also 1GB plans from MVNOS that seem to start around $12/month.

Anyone have any experience with IOT cellular and what vendors to consider?  I’m favorable to the idea of digi-key as a tinkerer …

Thanks.

Charlie
