>I know these are used in restaurants to monitor refrigeration temperatures.

Do you know what the minimum allowable temperature is for refrigeration monitoring? As in, do you know if these tags can be used in a dedicated home freezer?

Also - how is integration with Home Assistant? I'm currently slowly migrating all my zigbee & zwave components off Samsung's Smartthings to HASS. Lot of my sensors are several years old now. So first thing I'm doing is slowing replacing them with current gen zigbee and zwave sensors and switches. I'm carefully evaluating each type of sensor and buying them from manufactures that are widely supported by the HASS community.

Edit: Looking at their product description for their smart tags with temperature sensors - they indicate that they're "Not optimized for usage in freezer.". So that answers my first question.

Their cheaper tags are not for freezers, at least for commercial low temp applications. But the more expensive ones work in freezers

I have really only used these for refrigeration and monitoring access to liquor cabinets in a commercial environment. I user their apps and have some notifications via Pushover.

I have a back burner project to integrate their open/close switches with our Hue Lighting. But have only researched the possibilities. But their website describes how to setup lots of automations and integrations

yeah, I just noticed that they have couple of heavy duty sensors that are listed under the probe section that seem have temp range as low as -50. So those would be ideal for standing freezer.

They don't seem that expensive either. https://store.wirelesstag.net/products/outdoor-probe-basic

Good to know about pushover. That's been my preferred notification service for many years.

They also have an API. Although not sure if it runs locally or on cloud. I'll have to do some reading. - https://www.wirelesstag.net/apidoc.html

Thanks for the recommendation.
