There are several experimental indications of sterile neutrinos with a mass in the 1 eV ballpark and many experiments are trying to clarify the situation.
During 6 years the DANSS experiment collected more than 6 million inverse beta decay events and measured the background level during 4 reactor-off periods. Data were collected at 3 distances (10.9 m, 11.9 m, and 12.9 m) from the center of the core of a $3.1$ GW$_{th}$ reactor with event rate up to 5 thousand per day. The detector position was changed frequently usually 2-3 times a week. Therefore many systematic uncertainties were canceled out in the analysis. After collection of additional 0.7 million anti-neutrino events
the significance of the best-fit point in the 4$\nu$ case increased from 1.3$\sigma$ to 2.35$\sigma$. This is still not statistically significant and we present
the exclusion area that covers a very interesting range of the sterile neutrino parameters up to $\sin^22\theta_{ee} < 0.004$ in the most sensitive point. In particular the DANSS experiment excludes a large fraction of sterile neutrino parameters preferred by the recent BEST experiment results including its best-fit point.
The inverse beta decay event rate dependence on the fuel composition was measured. It agrees with predictions of the Huber-Mueller model. During almost 6 years the reactor power was measured with $\approx1.8\%$ accuracy in 2 days using the anti-neutrino event rate normalized to the reactor power at the initial period.
