Why am I getting indoor and date info correctly but not outdoor. I hav

I'd test a couple things:

1.) Use brand new batteries (just to isolate the issue) if the old ones are ok, you can always put them back in.

2.) Put the unit in the same room as the receiver

• If the bars increase, then you might have an interference issue. I would move the sensor further and further away from the receiver until the bars drop. And that'll be your culprit: maybe there’s a wall with a lot of metal (ducts, wiring, etc.), or there’s a big electric motor running nearby (HVAC, old refrigerator, large CRT TV, etc.), or there’s a faulty appliance creating interference (microwave oven, etc.).
• If it is interference, you may have to move one or both of the units.
• If the bars do not increase, then you know there's something wrong with either the sensor or receiver.

Acurite sells both the sensor and receivers separately:

To be honest, if this is your only unit, it’s probably more economical to just replace the whole system. From Acurite, the replacement 5-in-1 sensor is ~$100 and the receiver is also ~$100.

Where it becomes a no-brainer is that on Amazon, you can buy a brand-new Acurite (5-in-1) system (receiver + sensor) for ~$125:

Or COSCO for a La Crosse 5-in-1 Professional Wireless Weather Station for ~$99:

I hope one of these tests proves fruitful, if not reach out to Acurite’s customer service…they were VERY helpful and responsive:

Complimenting the previous post's suggestion of simply replacing the entire 5-in-1 weather sensor - which is probably the easiest method and quickest.

BONUS: if the new Acurite replacement system is compatible with your old receiver, then you'll have one new sensor and two receivers (like one upstairs and one downstairs).

Alternatively, if you like to tinker, Acurite makes their units REALLY serviceable.

If this is something you'd like to try, please read on:

Once you've resolved the connectivity, and are sure you are receiving data from the unit, is the temperature from the unit reporting unusually high?

If so, another item to check is the temperature sensor - it is a plug-in board that goes bad over time INSIDE the 5-in-1 sensor.
It's only $16.49, and is pretty easy to swap out (once you've opened the unit you can give the inside a REALLY good cleaning - bugs, debris, etc.).
