January 10, 20233 yr Will these run on the Beaglebone black? It has eMMC storage built in - so shouldn't suffer from the SD card failure like the raspberry pi's
January 11, 20233 yr Author 16 hours ago, Sc00bs said: Not sure that you will still need Solar Assistant if you set up Home Assistant with the Sunsynk integration. They get pretty much the same data from the inverter, you just have a lot more freedom withg how it is displayed and in integrating with other devices in Home Assistant. IMO Solar Assistant is for people who don't have the time/technical expertise to be able to set it up the connections for themselves. Maybe someone who uses Solar Assistant can comment on the advantages, if any, over Home Assistant. I dont have programming knowledge, but it seems that there are guides available for people wanting to setup different things in HA. I am borrowing the pi 3 for the next few months from a friend. So I will see if I can get HA integrated to view and change inverter things. If I can get it to work, then I will use the SA pi for HA.

Microwave is easily readable from most places due to open plan. added bonus is it goes peep when power is back.. None the less. The OP should just use a NO relay for this. easy as pie... And not dependent on www access etc.. He can even run those loads he does not want on during load shedding using the same relay setup
January 12, 20233 yr SolarAssistant + Home Assistant is awesome. My dashboard on a small tablet: Bedroom and Study A/C is on a Tuya smart plug which automatically switches those plugs off during loadshedding, high inverter load etc and back on based on certain values being met. The grid status is a custom button that goes red when we have loadshedding and I also have a couple of Google nest speakers in the house that play an alarm when loadshedding starts and a notice when it ends. Pool pump is also automated in this way with certain parameters. You could easily install a single Tuya compatible led downlight that is RGB and let that go red when loadshedding kicks in using HA. Just that your light switch would have to be on though. Its just an idea. I managed to do all of this just by following instructions and googling - I have no coding experience - just IT literate. PS. Bob is my Robot vacuum - a previous poster said HA is a rabbit hole LOL. Cheers Douw Edited January 12, 20233 yr by Douw G. Gerber

I currently have a lot of tuya smart devices in my house Remember SA is more for Solar / Inverter monitoring only. HA then takes this to the next level by allowing you to change device state based on Solar / inverter status. e.g. If there is loadshedding in the next 30mins but the battery is below 50% then use the grid to charge the batteries. Then when LS hits turn off any appliance using more than 500w

January 12, 20233 yr 5 minutes ago, Terminal3k said: so HA talks to SA to get data? its advisable to keep both SA and HA? or can HA replace SA? They serve similar but distinct functions. You can have SA alone but that won't allow you to do automations. You can monitor your inverter and change settings from a web / mobile app. You could also have HA alone and that would allow you to control lights, speakers etc but you wouldn't know what your solar / inverter system is doing. Having them both allows you to then do automations based on what your solar is doing

Home Assistant is open source and free - you only pay if you want remote access from anywhere You need this cable to connect to your battery: https://solar-assistant.io/shop/products/shoto You need this cable to connect to your inverter: https://solar-assistant.io/shop/products/voltronic_rs232 if you have the RS232 port Cheers

January 12, 20233 yr Author Thanks, I will look at that for an option. Hoping to pick up a second hand pi for cheaper. I'll see what I can find.

What parameter do you use to identify load shedding? at the moment i am using if voltages goes below 100v. I was wondering what is best?

You could also create a threshold sensor that will then give you a binary sensor with ON / Off based on the grid frequency / voltage
