Do you have RSSI.dat file for this MMDVM_HS?
edit content of the file RSSI.dat located within
Expert mode - http://192.168.1.xxx/admin/expert/edit_mmdvmhost.php
Find field : RSSIMappingFile
Edit the RSSI.dat file ::
SSH - http://192.168.1.xxx/admin/expert/ssh_access.php
Location :: /usr/local/etc/RSSI.dat
I used Putty to logon/access the file on the pi-star device and edit the file at that location
Location :: /usr/local/etc/RSSI.dat

#The data to RSSI.dat
#Values in the RSSI.dat file are obtained using the MMDVMCal calibration program (S mode),
#the high-frequency generator and the Motorola GM340UHF radio station.
#For different radio stations, the values are slightly different.
#For example, for those GM340 that I had, the discrepancy is about 10 dB.
#Therefore, it is desirable to carry out calibration for each radio station.
#More about RSSI and a homebrew MMDVM node you can read here #https://drive.google.com/file/d/0B_UNZTdPtyZUUjN2d2llV0RtNTQ/view
#but unfortunately in Russian only

| # This file maps the raw RSSI values to dBm values to send to the DMR network. A number of data |
| # points should be entered and the software will use those to work out the in-between values. |
| # |
| # The format of the file is: |
| # Raw RSSI Value dBm Value #output voltage |
| # |
| # The following values were measured with a Marconi 2024 signal generator. |
| # Setup is MMDVM (PCB by Toufik, F0DEI v1.1) on a STM32F446RE Nucleo board. |
| # The values in the comments are the voltage measured at the GM340 RSSI output pin. |
