## Questions & Answers

**Q: Is this only accessible through an app? i want to get to the interface by entering an ip address into a web browser. thanks.**
A: Not quite sure ! Yes works well through the app which I use. Have read that you can access certain items via ifttt and a raspberry pi.Ewelink do do a Web interface on PC but you have to pay for it! .

**Q: No earth terminal? i want to use the sonoff switch for my immersion but it looks like there is no earth terminals. any solutions? uk type wiring**
A: Mount an adaptable box (4x4”)  below the sonOff take all cables through this box to the sonOff and leave the earths in the box joined in a connector.

**Q: Is this suitable to connect directly to an immersion water heater from a switched spur?**
A: I've been using the 20A model for the last month and a bit with my immersion heater.

Keep in mind:
1) I'm not an expert on the IET wiring regulation.
2) These new models do not have any built in cable clamping on the cables insulation. This is going to leave some risk of live cables accidentally getting pulled out. I've added external cable clamps to mitigate this risk. 
3) The flex to the immersion heater should be the heat resistant type. 
4) Normal practice is to have an immersion heater on its own dedicated circuit back to the fuse box. This ensures there is no chance of overloading the cables. I think you are allowed to run off a spur but the 13A current for the heater is going to be using nearly all the spurs capacity of 16A. So no sharing with anything else.
5) The 20A model is only a few pounds extra, can't hurt to have a more robust relay switching the current and in life the less you push things to their limit the longer they tend to last.

**Q: does it work without a smart meter?**
A: Yes. It’s simply a mains voltage power monitor. I have mine between the grid tie inverter and the socket I have back fed into. Works very well. I had some trouble pairing it but eventually it worked. Very handy seeing the solar power being fed into the house in real time.
