Clever. Larry - which one-wire temp sensor you are using  with the esp32? Or maybe diy?

The "Classic" charge controller / Re: Local App/ Classic monitor...

Last post by ClassicCrazy - January 30, 2026, 12:02:34 PM

I have internet to my unattached non heated power room. I have built an insulated box around my batteries and have a small space heater in it . It is controlled by an Inkbird temperature sensor that is the wifi model. I can see the temps and also change the setpoints remotely either using their app , or there are ways to do it without using their app . I also use esp32 flashed with Tasmota firmware and one wire sensors on them to see temps in various places. The esp32 have built in webpage and they can be accessed from your home network via wifi.
I also have mini split in the power room I can remotely control. In fact the sun is out and batteries full so I am going to turn it on . I use Home Assistant to monitor and control everything around here - batteries, inverters, controllers, switches on stuff, etc. There is a bit of a learning curve with Home Assistant but it is a powerful open source software tool for control and monitoring worth the time investment in geek work involved to figure it out.

The "Classic" charge controller / Local App/ Classic monitor tem...

Last post by Corndog - January 30, 2026, 10:51:54 AM

I noticed in one of Ryan's tutorial videos his AUX on the local app was reading the temperature of his freezer, I believe thats what he said. If this is what I thought I witnessed how is this done. I really need to monitor the power house temperature to make certain the furnace is keeping up, -30C lately and reversely the summer temp as well.
Thank you

Just paint the end of the barn white and you will get plenty of reflection.

I'll second what Larry said.  Also run a Classic 200 & HB to charge the same battery bank, works great.

Dave

Thanks, I kinda figured they might work together but wasn't sure.

Right now, looking for new solar panels. I'm not going to drive down the same road and get used panels again.

If you are putting the panels on a ground mount , look for bifacial. They really do pretty good in the winter with snow reflecting light on the back of them. I got some this past summer for around 23 cents a watt and $200 flat rate shipping for a pallet. Sometimes signature solar has some good deals - or at least they did last summer.
Larry

I've been thinking that might be the way to go. However, that being said, here is a large barn right up against the solar panels, and even with a good Ohio snow storm, very little snow gets under the panels. There isn't much of a price difference between the two, and my thinking is why not use the bifical panels.

The attached photo is the battery/off grid solar array. About 7.5kWp
