Spa automation

[smoothe]

Hey all I have a me mechanical timer on my spa that activates the actuators so the pool heat via a flow sensor just heats the spa. I want to keep this as it’s perfect for guests however I want a wifi control. Can I just pop in a 24v relay where this connects to the power? Like this?

What model mechanical timer?

Where will you get the voltage from to power the WiFi relay?

Show us a pic of the timer.

Hi this is the timer, I had a quick look at the current wiring I’ll open it up again but it looks to be connected to this 24v switch

Re the voltage question not sure was hoping I could tap into something

Which contacts do the mechanical timer wires connect to?

You need to find a place to power the wifi switch from.
