The church I attend receives USDA food to distribute to the poor. The reporting requirements have gotten more burdensome after the local supply contract changed hands and the last federal money allocated expired in May. We are now being required to daily transmit temperatures by email for the dry food storage closet, a box freezer and a common upright fridge/freezer, all in different rooms, but all within range of wifi. This wifi requires a login password for internet access.
Is there an affordable device that would transmit local temp by email once a day? It should be battery powered, but could be plugin as there are outlets within easy reach at each location.
We are present most 5 day weeks, but never on Saturday or most holidays and to read manually and transmit now requires someone with keys to the building and storeroom and refrigerators/freezers. Those must be locked down to control inventory. The inventory is supposed to be transmitted daily, but it doesn't change except on days when a responsible person is on site, so we should be able to just tell them that.
I would need one device that reads common office room temps, one that reads fridge temp (32F/0C up) and two that read freezer temps from 32F/0C down to -20F/-10C.
The ability to automatically send a simple text email to a specified address is a requirement, otherwise it will still require manual intervention.
