I bought two of these to try and manage TOU discharge scheduling for two Sunsynk devices.

I did some research beforehand and understood that I could enable MQTT on each SolarAssistant device and point them to a broker in the cloud and then configure the rules table on each device from there.

However, it appears the only MQTT option is for the SA device itself to be a broker.

Am I able to achieve scheduled charge and discharge on a SunSynk by controlling Solar Assistant remotely over MQTT or REST-API or otherwise?

This is what i use through Home Assistant but can also use MQTT Explorer to send / change settings - works flawlesly

Which settings do you change via HA to achieve this?

Sorry for the delayed reply - didn't see the notification

In HA i get a number of entities using this MQTT integration - an example >

or

These are simple because they come in already setup as switches so i can use a card to toggle them on or off quite easily.

Other entities come through as number values so a slider card might work best, e.g. setting the rate of charge
