I bought 6 of the new Room sensors that connect up to the Thermostat. These things look REALLY good!
The magnets in these things are REALLY strong! The batteries were really strongly attracted to them (both in the sensor and the sensor stand).
You can easily decide which sensors are included in Comfort Control or not by selected the plus or minus in the different sections to move them to the other section (as shown below).
You can also select which ones are used for Comfort control during the day time vs night time by selecting or deselecting the House icon or the Moon icon:
You can set a “Threshold Temperature” (Ex: 6 degrees) for each sensor to where if one of the sensors varies from the Thermostat temperature by more than that amount, it will show a red warning for that sensor, indicating it has a huge difference there, as you can see on 2 of the sensors below:
Each sensor also lets you select how you would like the Thermostat to manage hot/cold spots. You can set it to:
- Prioritize Saving (which I believe means it will give less concern to temperature differences with that sensor and more priority to the average of the other sensors)
- Balanced (which I believe means it will count toward the average of all of the other sensors selected as balanced)
- Prioritize Comfort (which I believe means means the thermostat will continue to go until all sensors labeled this way reach their set temperatures (though other areas may still vary in temperature)
The battery level is just an icon in the settings - Device Info page
By comparison, the HMS climate sensors battery level just says a word like Normal or Low.
Climate sensors have Push Notifications for Temperature/Humidity highs or lows, and Rule triggers for Automations, TStat Room Sensors currently do not.
- Unlike the HMS “Climate sensors” that connect to the Hub, these “Room Sensors” which connect to the Thermostat do not currently have notifications to tell you when a temperature goes above or below a certain temperature, nor do they have rule triggers to do automations (for example, I have a space heater connected to a Wyze plug which is turned on or off automatically solely based on what the Climate sensor determines the room temperature to be. If it gets too cold, the Climate sensor automatically turns on the space heater for that room, once it warms up the room to a certain temperature, it shuts off the heater automatically, keeping the room at a pleasant temperature. If I leave the room for more than 10 minutes, the heater is also turned off (and as a fail safe, if the heater is ever on for longer than X minutes, it also auto-shuts-off). I am also able to put these right above my stove and then I get notifications when the stove turns on (goes above set temperature) and when it cools back to normal temps (drops back to below the “too hot” temperature). These more recent Tstat Room Sensors cannot do any of those automations or notifications that are possible with the climate sensors.
- The Climate Sensors Have cool stats!
NONE of the above stats are possible with the Tstat Room Sensors
- The Tstat Room sensors LOOK AWESOME with their display, and you can view their temp and humidity at a glance without looking at the app; though the Climate sensors are less conspicuous and easy to place almost anywhere. Both are easy to mount to a wall or set on a shelf or whatever you want:
As you can see, I am currently leaving several placed near each other so I can see how consistent they are with their measurements to each other (to be discussed more in a minute).
- Room sensors have a motion detection sensor so the Tstat can determine if the room is occupied, but you can not view this detection anywhere in the app (the sensor display itself will show a little dot on it for somewhere around 16-20 seconds when it detects motion though) or use it as a motion sensor for automations or notifications or anything, it is solely for the temperature calculating ability currently.
- The Room sensors currently can be used for determining what your HVAC system is doing. The Climate sensors may or may not have this ability in the future. Wyze previously indicated they were researching how to make it possible for the Climate sensors to work for temperature averaging use with the Thermostat, but that capability is not possible at the time of this writing.
- The Room Sensors take 2 AAA batteries (YAY! I can use Rechargeables when the batteries need replacing 3 years from now) while the Climate Sensors use a Button Cell Battery (which lasts 18 months, so that’s great too).
- The Climate sensors are more affordable, presumably because they don’t have a display, are smaller, etc.
They are pretty close to each other, and often the same. It seems the climate sensors are just a tad more sensitive to humidity, and temperatures are almost identical. The few differences reported could be explained by things such as the Climate Sensor sitting flat on a surface, while the Room Sensor is on a stand. In the Family room the difference could be that they are slightly farther apart, see the above picture with the Room Sensor under the TV and the Climate Sensor above a doorway. That would perfectly explain the differences there for example. Most of them were next to each other though. All in all I would say they are pretty consistent with each other and certainly within reasonable tolerances. That is reassuring.
Things I wish would be changed:
- Add stats, Push Notifications, and Rules similar to what the Climate sensors have.
- Allow us to have more than 6 of these used toward the “Comfort Controls”
- Add Google and Alexa Access
- Enable the Thermostat to be able take the readings from these into account when averaging the household temperature
- Add Google and Alexa Access
- Be able to pick which sensors are used or not used for the HMS Environment Stats
Overall, Even if nothing changes for either of them I like both of these sensors, but they currently are definitely better at different things than the other. I will be keeping and using both sets of sensors, though I will likely redistribute them into different areas of the house now (Room Sensors get priority for places I want considered for HVAC controls, and Climate sensors for other areas I still want monitored, though a few critical rooms will still have overlap with both sensors in the same room.
