It worked as advertised
I had recently bought a Rinnai tankless water heater. Before we had a strong Winter freeze here in Texas it was recommended that we set up the "recirculating" function that came with the heater. My wife wanted to have more control over turning the function on and off. The most convenient way of doing this was to get a Rinnai RWM200 which communicates to the water heater via WiFi. It works great and was easy to install. I'm very happy we have this device. Now I can control the heater functions from anywhere!

Disconnects too often
The device is reliably built; the software appears to let it down. The device will drop out often and can make schedules incredibly unreliable. The tankless water heater can easily learn a crude use pattern and apply recirculation based on the observed usages but the WiFi module replaces that are otherwise a programmed schedule for activation of the recirculating pump. It's day to setup schedules it the unreliability of the module means that the schedules might not actually happen. I would recommend it but with caution. Hopefully Rinnai will release a software update that addresses reliability.

Good price, shipping super fast!
The module is easy to install. The app's design seems focused more on manage and scheduling of recirculating pump. I didn't have recirculating pump, so it worked only on temperature control only.
I suggested Rinnai add a power on/off function on Apps so it will work more like a physical remote controller. So we can turn off the heater when not using it, and save some power.
