I am suggesting that (1) each facility could have multiple Ohms - depending on the needs of the facility.
Otherwise, (2) - whether they do or don't have >1 Ohm, the Nestle factories are likely to contribute to >15% of the revenue requirement (to justify a A$B valuation) simply by virtue of the fact each facility will require multiple sensors - making the price per facility much more than the anticipated US$750/month.
I note Digicel has been been selling bundles up to ~US$2,300 per month. It would seem reasonable to expect a factory, likely also requiring a vast amount of sensors, to come out at some similar price point per month.
