Building on the post [Gas meter from Xiaomi/Aqara door sensor (ZigBee)
(Gas meter from Xiaomi/Aqara door sensor (ZigBee))
My utility company is converting over to smart meters. For electricity and water they have replaced the meters. But, for the gas, they retrofit the meter. The retrofit added a device that attaches to it with reed switches and a magnet. The magnet attaches to the two feet dial, which for one complete rotation it used 2 cubic feet.
The biggest problem I had was attaching the sensor and external reed switch. So I designed and printed a bracket.
This is the reed Switch:
