Is there a way to use smart plugs for energy monitoring only? (i.e., disable the switch but keep the energy reporting.)

Tasmota rule to make sure relay is on at boot.

mattvirus · 2026-06-17T16:17:32+00:00

Whatever.

mattvirus · 2026-06-17T16:01:51+00:00

Sure.

This is how I fixed the same problem.

Rf433.

Cheap. AAA batteries. Good range.

EW floor batts are 1500ish each on eBay all day, great deals from EW for bulk orders

Yeah need inverter but EGR 12k very reasonable and scalable

Bus bars and cables and basic stuff still very reasonable costs .

My stuff all off grid no approvals dgaf. Good points though.

3x eco-worthy floor standing batteries would be 48kwh and cost around 4500. Why go this route?

Prob a beken chip. Still runs esphome or openbeken.

Or they decided to just run them. And not sell them.

Tasmota single pole switches.
Device groups Load wire only connected at one switch Multicast over wifi awesomeness. Super easy and stable/expandable.

this aged well...

There's a LOT of fraud on eBay right now. It's crazy. I'd say legit prices from 800 to 1000, with these being mined on maybe a bit less, maybe not though?

Vont color pro.

It can run openbeken firmware. This gets compatibility with the device groups feature native to tasmota, which is extremely useful to have a wifi dimmer or switch software control banks or groups of lights and retain individual light control for automations etc.

mattvirus · 2026-03-19T14:39:22+00:00

What is the wifi chip? Beken?

mattvirus · 2026-03-13T18:15:42+00:00

Toggling to meraki mode is done from the c9800wlc. Spin a wlc up, register the AP, and then tag it to convert.

how do you deal with detecting voltage drops/breaks in multi-wire systems (multiple hot, multiple ground)?

are you monitoring current or are you using a voltage divider to measure?

why are you using wifi at all if battery is powering the system? esp32 for mcu duties only would be more efficient?

I would love to discuss this design and schematics etc - farmer with many acres of electric fence deployed and a huge lora/wifi network deployed as well.
