Refoss EM16	Works Local	Local HA integration, updates about every 20 seconds Saved copy SEM-Meter direct integration with MQTT with current firmware updates every 2 seconds. Refoss EM16 Refoss has its own direct local HA integration updates about every 20 seconds. Emporia Vue Has a cloud based integration updates every minute. But is flashable to ESPHome. Priced low to high. Im using the SEM-Meter currently and tracks as well as the Emporia Vue 2 I had installed that is now in use at my parents house so mom can track her usage. I ordered the Refoss before I had the SEM and is well outside the return date so Im gonna see, hoping, if the WiFi reaches the remote meter base to … Excerpt saved from the Arctic Shift Reddit archive on 2026-10-23.

Refoss Smart Energy Monitor EM16	Partly works Local	Stopped reporting after firmware update; power cycle restored Saved copy It stopped working for me too. The Refoss LAN HACS integration worked fine as a substitute for my em16 though. Excerpt saved from GitHub on 2026-10-23.	Issue #161280 · 2026-01
Refoss Smart Wi-Fi Switch R10	Partly works Local	Needs same LAN for discovery; no manual IP entry Saved copy The problem I have been careful (or so I thought) and purchased a number of Refoss R10 switches, power meters and as it seems they cannot be integrated due to the way the Refoss integration works. I have a home assistant server a few states over that is connected vis a VPN to my local LAN. the connection is routed, the connection is very stable, and thus far every device I was able to inetrage by typing in the IP address of the device after it had been set up in my local LAN and given a static IP.

Refoss EM06P / EM16P	Requested	P variants not supported; PR closed Saved copy Proposed change Add in support for Refoss 'p' variants of the em06 and em16. Some background: When I purchased my Refoss devices I got the em06p and em16p (not sure if there is really any difference in the spec) and not the em06/em16. Since the device identified itself with the id 'emXXp' to the Refoss plugin, it did not work out of the box with these devices and with no errors thrown in the logs. After digging through the code, I added the devices as seen in this PR and added some logging which may be helpful to others in the future sin Excerpt saved from GitHub on 2026-10-23.
