IZAR meter under cast-iron cover

[crivchri]

Hi,

I successfully followed your installation instructions and managed to use your recommended solution (ESPHome + AZDelivery ESP32 Dev Kit C V4 + CC1101), to read the consumption of my Diehl IZAR RC I R4 meter.

However I have an issue with reading my IZAR meter, which is located under a cast-iron cover on the road just in front of the house (5 meters). When the cast-iron cover is open, I can read the meter, but when the cover is closed, no signal is detected by the meter.

What can I do to improve the signal and able to read my water consumption (with the cast-iron cover closed)

Thank you for your help and kind regards.
