ADC board with Wifi/Zigbee/Zwave

I’ll appreciate,
if someone can give me a pointer to a ready made board with several analog inputs to measure input voltages, so I can read some voltages going to a furnance.
Ideally the board shall have wifi connectivity. Zigbee or ZWave are also ok.

If such a thing does not exist, but can hint me towards a nice diy path, that will also be appreciated.
