Has anyone settled on a reliable handheld that can do Wiegand/OSDP line testing and basic credential reads while also checking 12/24V and strike inrush on site? I’m trying to replace our Fluke 115 + separate card reader + makeshift breakout with one rugged unit for retrofit days when we drop wireless escutcheons on Schlage ND and tie them to an Altronix eFlow-6D. If you’ve used something that survives parking-lot installs and plays nice with DESFire EV2 and Schlage MT readers, I’d love the model and any gotchas.
Haven’t found a true all‑in‑one. I pair Proxmark3 RDV4 + Pi/libosdp (Open Source Data Platform · GitHub) and Fluke 376FC for strike inrush on eFlow‑6D.
I keep a “handoff clipboard” by the centrifuge: every transfer gets time/initials plus a quick barcode scan; it’s saved me during those patient-shift pileups. For lot-to-lot, I run a 5-sample bridge (low/mid/high plus two known troublemakers) and log deltas; if you’re slammed, at least do high/low QC. Little mantra on our bench: “label before you leave” — like keeping keys on the same ring so nothing walks off.
Building on @grantf_53, I use a Proxmark3 RDV4 for reads and a Pi Zero with an RS‑485 dongle running libosdp (https://github.com/osdp-community/libosdp) to monitor/line‑test OSDP. For strike inrush on the eFlow‑6D, I drop a 0.1Ω/5W shunt inline and grab peak via min/max on the DMM (I=V/0.1) instead of hauling a big clamp — no unicorn, but close. Would a tiny Pi in the bag count as “one unit” for your crew?
Closest I’ve come is a Klein CL390 for peak capture plus an M5Stack Core2 with an RS‑485 hat running libosdp and a tiny Wiegand tap — packed in one case it feels like a single kit, but it’s not a unicorn box. Quick tip: zero the clamp and use “peak” before powering the door so you catch the coil surge; @taylor57k, seen anything truly handheld that combines all three?
I haven’t found a true single handheld; my “one case” setup is a phone running libosdp in Termux via a tiny two‑wire bus adapter, a Proxmark3 RDV4 for reads (GitHub - RfidResearchGroup/proxmark3: Iceman Fork - Proxmark3), and a 0.05 Ω inline shunt so your meter’s min/max catches the latch peak — Swiss‑Army duct tape, but it works. @sara_m_82 seen a real all‑in‑one that does shunt‑style peak cleanly?
Saw the same “patients shifted” while QC stayed green — we set a moving‑average rule in middleware: rolling 30 patient creatinines, alert if mean drifts >3% from the prior 7‑day baseline; it caught a reagent top‑off dilution before controls moved. Small caveat: it’ll false‑flag when case mix swings, so we snooze it during ED surges, @charlieG45.
