Yes, you have to reduce the IR output of Tx.
You can check with your phone camera for the IR signal to be sure which one is Tx.

Battery lifetime notice
Reading the meter via the IR interface has a direct impact on the battery lifetime.
According to the manufacturer, the expected lifetime is around 16 years – however, regular polling will reduce this.
The exact impact is currently hard to quantify and needs to be observed over time.
For this reason, I have:
- increased the polling interval to 120 seconds
- disabled additional values such as flow (L/h) and temperature
- and explicitly included battery-related data to monitor long-term effects
I just tested and putting a piece electrical tape over the TX did the trick. Thanks for the help!

I can read data for about 12-14 hours until it stops. I have to trigger the magnet again by removing the sensor and put it back into position. Do you have the same issue?
How did you mount your sensor?
Mine has been continuously reading data for a few days now without issues. At the moment I have just carefully placed the ESP on the meter and hope to god that it does not get bumped 
I’ll have to look into printing that bracket.
Good and bad news for me 
Can you share a picture of your position - without - touching it!
Seem, that I have to improve my braket.
