Home automation, part 1 of some?
First some background; Rob and I bought a house late last year and since then we have been working on setting up the smart-house systems we want. We have been doing this while waiting for tradespeople to do the various upgrades we want before we move in.
Late last week we reached the point that it was possible to do a test-run of most of what we'd set up, such as NSPanel EUs in the main spaces downstairs. We've also had Candeo dimmers or switches installed to control most of the lighting and so on.
As such, our house "network" of Zigbee and WiFi devices is quite complex. We powered it all on over the course of one evening and everything, despite being off or out of contact for a few weeks pretty much came back fine. Except for one thing - the Hive controller for the boiler. Long term this won't matter too much because we've had an air-to-air heat pump installed so the majority of the heating will come from that. The boiler will, pretty much, only be used for hot water which doesn't need the Hive to work.
Re-pairing the Hive was a thorough pig because the receiver has a single button and a single multi-colour LED and that's the entirety of its interaction surface. Unfortunately I have a bad back today, and poor Rob is colour-blind which really made it hard.
Anyway, after all that background/whinging, here goes the main purpose of this post. We intend to replace the Hive with an esp-32 talking to the eBus interface on our boiler (a Vaillant thing) and I was wondering if any of you out there in the wider world had ever used such a thing? How hard are they to power off the boiler, etc.?
We ended up plumping for an eBus adapter stick and we're waiting for it to get here. I'm slightly afraid about when it comes to fitting it because the Hive we currently have is on the mains-voltage controls, which will have to be safely disconnected. Is this something someone I know has done? Will it be easy for me or should I get an electrician in? Boiler YouTube doesn't seem to want to help me out ðŸ˜.
