Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

i have used these devices for years and found some interesting things.... Juntek vac4300 ...

PRO:
very handy for state of charge, bi-directional current sensing..
seem pretty accurate...

CON:
the wireless signal is quite dismal, 10-15 meters advertised.. .bout that in real life..

so lets fix that, it uses the standard NRF24L01 modules... sweet order some palna+ versions , like this NRF24L01 palna+

matter of squeezing them in... sorry only took finished pics, but you get the idea..



first pic, installed in the "sender " unit, i have 2, one does wired in shed, other is inside house.













Happily transmits inside about 30-40 metres away, with 2 walls.. happy camper







I think it works !!

That's certainly good to know that will work.
I bought a few of those Wifi NRF24L01+PA+LNA modules and a bunch of the regulator modules as well, for another project.
You receive the data to your phone or something else?
