Hi Jim, I am afraid that the main problem is in '%.1f' in the "lookup table" when UPS returns "--.-" (string) instead of "12.3" (float):
root@OpenWrt:~# printf '%.1f \n' "12.3" 12.3 root@OpenWrt:~# printf '%.1f \n' "--.-" ash: invalid number '--.-' 0.0 I checked source codes at https://github.com/networkupstools/nut/tree/master/drivers and all these protocols have similar "lookup table": - nutdrv_qx_zinto.c - nutdrv_qx_voltronic-qs.c - nutdrv_qx_q1.c - nutdrv_qx_mustek.c - nutdrv_qx_megatec.c - nutdrv_qx_megatec-old.c - nutdrv_qx_mecer.c - nutdrv_qx_hunnox.c - nutdrv_qx_bestups.c BTW - I already wrote some "basic" code in Python using PyUSB to read desired data from the UPS, but the communication with it is very very bad. Probably due to the bad the quality of the electronics in it. Sometimes it returns data with missing initial characters (missing first 8 bytes) so I have to re-read the status, sometimes the communication freezes completely so I have to power-cycle the USB port.

Ahoj, Just in case, did you check other subdrivers there? They all are for variants of Megatec Qx family, UPS vendors were creative with it...Jim On Tue, Aug 16, 2022, 03:46 Tomáš Thiemel via Nut-upsuser <[email protected] <[email protected]>> wrote:Hi.
