Questions before you switch
Can I buy a Temp Stick in Canada?
Yes, but it ships from Salt Lake City, Utah. Temp Stick's free shipping is for US addresses only: Canadian orders pay a shipping fee (its FAQ says it averages US$25), and Canadian customers pay all duties and taxes. Prices are in US dollars: US$149 for the Temp Stick (regular price US$159) and US$169 for the Temp Stick +Power. A Canadian EDGE order ships from within Canada, so it never goes through customs; it is charged in Canadian dollars, with free shipping over $100. Temp Stick facts from tempstick.com, checked on October 14, 2026.
How is EDGE different from Temp Stick?
Both send text alerts, and neither needs a subscription on WiFi. EDGE also phones everyone on your list, sounds a buzzer on the device and shows the reading on its screen. EDGE Thermo watches a fridge and a freezer from one unit with its two probes, and every model comes in a Cellular version that needs no WiFi (Temp Stick lists WiFi models only).
How does Temp Stick work?
Temp Stick, made by Ideal Sciences in Utah, is a WiFi temperature and humidity sensor. It runs on two AA batteries (the +Power and PRO can also run on AC power) and joins your WiFi with no hub; the PRO adds one temperature probe. When a reading crosses your limit, it alerts the people you choose by text, email or app notification, with no monthly fee. It needs an active WiFi connection, and for its power-outage alerts to reach you during an outage, Temp Stick says the sensor must be plugged in and your internet equipment must be on a backup power supply (UPS). Temp Stick facts from tempstick.com, checked on October 14, 2026.
Can it call my phone and text the whole team?
Yes. When a reading crosses your limit, everyone on your list gets a phone call, a text, an email and an app notification, and the buzzer on the device can sound too (switch it on in the app). The alarm repeats until the reading is back in range, and a team member can snooze it for up to 24 hours by acknowledging it and entering a reason. On WiFi the list is unlimited in year 1; after that, adding new people needs Premium, and people already on the list keep their alerts. Every device comes with about $3.70 of call and text credit (250 texts or 100 calls): about 1.5¢ per text and about 3.7¢ per call, so an alert that calls 3 people and texts 5 more costs about 19¢. Email and push alerts are always free.
What happens in a power outage?
Every EDGE runs on 4 AA batteries (about 2 years), so it keeps logging through a power cut. A Cellular model on USB-C power reports the power cut at its next recording (every 10 minutes by default) by app notification, email and text, over its built-in cellular link, so the alert does not depend on your router. A WiFi model can only send it while your router and internet still have power, so if outages worry you, choose Cellular.
Is there a subscription?
No subscription required on WiFi. Alarms, live data, 45 days of history and Excel export stay free; texts and calls use the included credit. Optional Premium adds advanced and PDF reports, full history and adding new people for about $17.78/year (about $1.48/month) per device, billed annually, and your first year of it is included. On Cellular, the 1st year of service is included, then about $26.67/yr (about $2.22/month) per device, billed annually; it covers the cellular network and Premium. Nothing is charged before year two.
Which EDGE should I buy?
Rooms, basements, cottages and server rooms: EDGE Essential (it measures room air). Inside a fridge or freezer: EDGE Thermo, whose two probes cover a fridge and a freezer from one device. Every EDGE logs each reading and alarm, with Excel export for inspections. Vaccine or pharmacy fridges: EDGE Pharma, with a NIST-traceable calibration certificate included. No WiFi where it goes, or worried about outages? Take the Cellular version.
