If you have more than one hotspot, make sure you place them 300 – 600m apart for optimum earnings. Do not place two hotspots in the same house, as it will only reduce your potential earnings by splitting them between hotspots. The higher up you place your hotspot, the better! Try to ensure there are no obstacles close by. Check out Helium.place to identity the optimum location to place your hotspot –  https://helium.place/
