Has anyone used 2 of these units (4 sensors) with refrigerator/freezer combos that are less than 30 ft apart? Do they operate on different freq?

Yes I have been trying to use 2 of these, one for the Ref/Freezer in the kitchen and an another unit's single sensor in a freezer in the garage. Unfortunately they try to talk to each other and get messed up with which sensor to read and display. For example, I get the same reading for the freezer outside in the garage as I do inside the house, but I know they should be different readings. I also tried using one sensor in the garage freezer and another to read the ambient temperature outside, but still had the same kind of problems. Both would show the fridge temperature instead of separate readings for in the house and outside. I've been looking for alternatives (wireless) but have had no luck yet. The manufacture needs to add a switch to change the transmit frequency used for unit one and unit two.

Maybe. Official answer here: https://support.acurite.com/acurite/topics/multiple_00986_units_working_together

You have to add the amps each appliance draws (starting amps, not running amps) and make sure it'sbelow the capacity of the unit. I ran 2 chest freezers at once, but never tried to run more at once.If the power fails I'll just run each fridge & freezer for an hour at a time every few hours.

I have four; one has the sensor facing the house and is a few inches from the wall. It does not affect its ability to detect light and it turns on and off at the same time as the others.

With the two I own, no. I suspected not, as there is no obvious way to adjust the send or receive frequencies. In most cases where multiple units are in use it would probably be necessary for each to act independently. Theoretically it could be possible to pair two or more sensors to a receiver during manufactured rather like multiple remote keys for a car, but I doubt if this would be done.

I placed sensors on the ground near washing machine, sump pump and behind my fridge where there is a water line. My logic was that if a leak does occur water will run down and trigger the alarm, The base unit is my basement mounted on the wall.

I have a Frigidaire 15,000 btu unit, about 3-4 years old. The remote that came with it was terrible. I bought the one you are asking about, programmed it in about 1 minute and it works perfectly. Never a problem, which is important as the unit is about 10 feet high. That has been my experience.

I don't see why not. I would put them on different time delays for a power failure so they both wouldn't try to call you at the same time. I assume you want two units for temperature monitoring.

In my house there are a few walls between the sensor and the receiver and it works fine. I don't know about your situation but I would give it a go.

We only have ours hooked up to the freezer, I assume you would need to buy another unit!

I have one installed in my upper level. I did have a freeze issue in the basement which stopped my heat. The alarm did go off and call but I wish I would have had one in the lower level to prevent some damage. If you find an answer please let me know as I too am considering having two on the same phone line. Will that work?

I use the sensor simultaneously for both the RMR391PA and the smaller EMR201 units. It sends signals to both very well. I use only channel #1 for both. I do not know about any other units; but there are several channels that can be programed with this unit. There might be several frequencies that it is capable of sending???

I am using mine at a range of about 40' and goin through at least two walls. Don't be tricked by the temp not changing right away. I was at first. It only updates like once a minute so give it some time and make sure the temp is changing in the test area. I like this. It works perfect for me to keep an eye on my deep freezers out in my utility room.

I have Model LRA087AT7. I programmed it and it's working fine. However, you need to aim directly at it and be at most 8 ft. away. It's a bit more bothersome and not as accurate as the manufacturer's but it works. There are 2 codes for Frigidaire and you can reference them in the code/manual that comes with it. If it doesn't respond after the initial programming, enter the code again. Eventually, it worked with the criteria I stated before.

Yes. that is what I bought it for and I have tested it with appliances. I had a problem with the first unit in that the humidity sensor was 8% off compared to two other humidity sensors I had. They shipped a new one to replace at no expense or even having to ship the defective unit back.

I have used these - and others from Radio Shack - with about equal runtime results in freezer circulating fans. None are very long-lived at cold/subzero temperatures.

Yes! I have two of these. One set monitors my fridge and freezer in the kitchen. The second set monitors my two freezers in the garage. I have both receivers magnetized to my fridge. All four sensors work perfectly. I attached labels to the receivers to remind me which display is monitoring which appliance. Which sensor is monitored by which receiver is controlled by battery insertion order. When you put batteries in a receiver and sensor, they synch up and lock onto each other. Just put the batteries into each sensor one at a time, pausing until you see readings on the receiver for each one. If you put them all in quickly, you won't easily know which sensor is being displayed where.

I, too, tested the low temperature alert on mine by putting the unit in the freezer. It worked just fine and the WiFi signal was strong enough to get out of the freezer and find its way to my router. I didn't leave the unit in there very long. I think the only way to find out how it will work for long term usage in a freezer is to give it a try. Batteries don't work well at low temps but you can monitor the battery status remotely. Good luck - I hope it works for you.
