Review on 🌡️ Inkbird ITH-20R Wireless Receiver Digital Hygrometer Thermometer - Accurate Temperature Display for House, Kitchen, Baby Room, Courtyard, Brewhouse, Public Places - Rainproof Function, Indoor/Outdoor Use by Ameen Bethea

As a home brewer and user of several Inkbird thermostats, I was excited to try this new product. This is a meter only, not a controller. After about a week of use with a temperature sensor, my impressions are: Pros: • AAA battery power for base station and temperature sensor(s) makes the system very portable. After a week of use the battery indicator is still showing a full charge • The base station is small and light but still has great visible readings • The temperature sensor is small and light and can be placed almost anywhere • Didn't try to push the limit of the transmission range, but with the probe inside the fridge, it will easily go through the fridge wall and at least two interior walls. The range is good. • Because the temperature sensor is wireless, there is no need to run cables through refrigerator doors, etc. • The supplied external sensor, which can optionally be used with the temperature sensor, is a nice addition. You will get two different reported temperatures when using an external sensor; one from the internal temperature sensor and one from the external sensor. Since each temperature sensor is a "channel" I was wondering how this would be represented as I didn't see it in the manual. If "Channel" is displayed for this temperature sensor; The reading quickly alternates between the internal and external sensors on the temperature sensor, and the "external" flashes to match the external sensor. Thus, when an external sensor is connected, the display shows THREE values of the total temperature: 1) Local temperature at the base station. 2) The temperature of the internal sensor of the temperature sensor. 3) The temperature of the external sensor attached to the temperature sensor. The accuracy of all three seems good and once installed it is within a degree compared to my other thermometers. Might be a good battery candidate if you plan on using it all the time like I did. • Delay Time – To conserve battery power, the sensor and base station synchronize via RF transmission every 10 seconds. Also, especially when the external probe is NOT used on the temperature sensor, the internal sensor is located inside the waterproof plastic case of the sensor unit and therefore it takes considerable time to register the temperature correctly when a large variation is required. Remember, if you put room temperature food in the fridge... how long does it take for it to "cool"? The same concept applies here. After I placed a room temperature sensor in my kegerator, it took almost an hour for it to adjust to the actual temperature inside. However, once it gets there it seems accurate, +/- one degree from every other thermometer I have. And it reacts much faster to small changes. • The external sensor is slightly faster, but both appear to be much slower at registering correctly than you would initially expect if you are a user of 120VAC temperature controllers or a thermal pen. This isn't your device if you need to capture large temperature changes quickly. So where could I use this? Anywhere where mobility is critical and in environments where temperature is not subject to rapid sharp fluctuations. I've tried this in my kegerator, fermenter, living room and outdoors. I think it will eventually live in my kegerator and give it a nice digital temp gauge which the factory didn't have. Where would I NOT use it? Anywhere fast and accurate measurement is required in a rapidly changing environment: mash water heating or mash temperature or anything that requires active temperature control as this feature is not supported at all. Thumbs up from me if used as intended. One more note; The humidity reading is within 5% of my Nest thermostat, but I don't know if that's accurate.
