I would like the ability to put a script/macro in for relay control that is triggered from VRM.
Here's the use case, might make it more clear.
I have an off-grid site up in the frozen north that is built to handle the temps, has 4 days of battery and 600W of power. The only problem is that the solar panels ice or get sticky snow on them which takes my normal overcast skies output from 100W down to 10W and that's not enough to charge batteries and run things.
I have added resistive heat strips taped on the back of the panels and triggered via relay. This works great, pulling power directly off the panels (via Y on the cables) and just a little heat is enough to get the snow and ice to slide off the panels.
I'm having to use a separate controller to handle this, which is of course using up a bit more power but also adds a layer of complication to the system.
I would much rather have a 'run for 10 minutes' button on the VRM dashboard for the site that would close the relay for 10 minutes and then open it back up. Simple as that.
Thanks.
