I think I’ll be able to scrape together an hour here and there to start tinkering with home automation. I already own two Raspberry Pi’s, a 3B and a 4. I’ve gotten to the point of installing Home Assistant on the 4 about two months ago, and haven’t done anything since. The 3 is running Pi-Hole, which used to be useful, now not so much (maybe I should update its lists).
Yesterday I took some time off and bought three Sonoff switches, two basics and one POW. Tested the POW last night using a janky setup with an old multiplug I had lying around and it seems to work great.
The idea is obviously not to be reliant on eWeLink’s servers. Therefore, now I need to get to the point of flashing Tasmota on these switches. @JacoDeJongh pointed me to a nice tool for the job, and I think I got the right one: https://www.robotics.org.za/W17939?search=usb%20ttl
When this arrives, my journey will start. So far I’ve decided upon the following order of operations:
- Install a remotely manageable switch on my pool pump
- Figure out how to make Home Assistant work and integrate the two (Jaco mentioned I’ll need an MQTT broker, which is also a new term for me)
- Figure out how to integrate HA with my Venus GX using ModBus
- “Smartly” manage the pool pump using the information from the GX
All of the above steps will be executed on my desk before actually hooking anything up to the pool.
A few questions to the community from my side are then:
- Please share any good tutorials on the whole Home Assistant, MQTT Broker, Sonoff with Tasmota with me, if you have available?
- Is this document from Victron, https://www.victronenergy.com/live/ccgx:modbustcp_faq, all I really need to know how to get it to work with HA, or do I need to read up some other stuff also?
- Any other useful things I can take on after getting the pool pump to stop being dumb?
- Please share any other useful information/potential pitfalls to avoid/good tools to get (I own a multimeter)?
